 OPINION 

¶ 1 After a stipulated bench trial, the defendant, Brandon Mumaugh, was convicted of 

aggravated driving under the influence of a drug (aggravated DUI) in violation of sections 

11-501(a)(6) and 11-501(d)(1)(C) of the Illinois Vehicle Code (Code) (625 ILCS 

5/11-501(a)(6), (d)(1)(C) (West 2012)) and sentenced to two years’ imprisonment. The 

defendant appeals his conviction. 

¶ 2 FACTS 

¶ 3 The trial court conducted a bench trial on October 17, 2014. The parties presented all 

evidence by stipulation. The following facts are taken from the parties’ stipulated evidence.

¶ 4 Mumaugh was 43 years old at the time of trial. He lived in Marseilles and had been a 

professional truck driver for 27 years. On June 21, 2012, at approximately 10:30 p.m., 

Mumaugh left work in Ottawa and began driving his GMC Blazer east on I-80 toward 

Marseilles. He exited the interstate at the Marseilles exit and proceeded south on Highway 15 

toward the Marseilles city limits. It was a very dark night with no moonlight. 

¶ 5 At the same time Mumaugh was driving home that night, 12-year-old Jennifer Dennis and 

her friend, 13-year-old Courtney Brown, were walking on the east side of Highway 15, at the 

edge of the northbound lane. Jennifer and Courtney had sneaked out of Courtney’s house to go 

the dollar store for soda. Finding the store closed, they continued north on Highway 15 in 

Marseilles toward a gas station, which was also closed. The girls then walked south along 

Highway 15 on their way back to Courtney’s house.

¶ 6 At 10:34 p.m., Maggie Thomas, a 911 dispatcher, received a call from Milan Najdanovich. 

Najdanovich told Thomas, “I’m on my way into town, and you got two little girls, they’ve got 

to be 12 or 14 years old, walking on Marseilles blacktop walking in between Hicks Gas and the 

Shell station.” Najdanovich said that “they’ve got no reflectors on, no nuttin’ Honey, they’re 

goin’ to get hit.” He added, “[t]hey’re wearing dark clothes. I’m really afraid somebody’s 

gonna hit ’em or something.” Within 58 seconds of Najdanovich’s 911 call, a squad car was 

dispatched to the scene. 

¶ 7 As Courtney and Jennifer walked, Courtney’s flip-flop broke, and she bent down to fix it. 

Mumaugh was driving south on Highway 15 at 50 miles per hour when he saw the white legs 

of a young girl (Courtney) in the northbound lane. Courtney was about 75 feet away.1

 Within a 

split second, another young girl, Jennifer, appeared out of nowhere in the southbound lane, 

immediately in front of Mumaugh’s vehicle. Jennifer was wearing black clothes and had her 

back to Mumaugh. Mumaugh immediately swerved his vehicle to the right to avoid striking 

Jennifer, but Jennifer was right in front of his vehicle. The left side of his vehicle struck 

Jennifer. Courtney heard a crash as she was bending over. Mumaugh’s vehicle veered off into 

a ditch on the west side of the highway. Mumaugh immediately exited his vehicle to give aid to 

Jennifer.2 He encountered Courtney, who said to him, “I kept telling her to get out of the road. 

 

1The parties stipulated that a vehicle traveling 50 miles per hour will travel 73.34 feet in one 

second. 

2Mumaugh had been an emergency medical technician (EMT) for approximately 10 years in the 

1990s. 
- 3 - 

I kept telling her she shouldn’t walk on the road.” Mumaugh and Courtney found Jennifer 

lying facedown on the east side of the highway. Her breathing was very labored. Courtney 

called 911. The 911 dispatcher received the call about eight minutes after the Marseilles squad 

car was dispatched. 

¶ 8 Highway 15 is a paved, two-lane road. At the time of the accident, the posted speed limit 

was 55 miles per hour. At the location of the accident, there were no lights illuminating the 

highway. The area is rural, and the highway is surrounded by open fields and bordered by 

gravel shoulders. 

¶ 9 At the time of the accident, Mark Judd was driving north on Highway 15 north of 

Marseilles when a Marseilles police squad car passed him with its emergency lights activated. 

The squad car stopped approximately one mile ahead. The officer exited his vehicle and 

directed Judd to stop. Judd pulled over and exited his vehicle. The officer, Brian Faber, saw 

Mumaugh standing over Jennifer, with Courtney standing nearby. Mumaugh told Officer 

Faber that Jennifer was walking down the middle of the road, that Mumaugh did not see her, 

and that he hit her with his car. Judd, a former EMT, walked to where Jennifer was lying to see 

if there was anything he could do to help her. Judd asked Officer Faber to help him assist 

Jennifer. Officer Faber did not respond. Judd asked Mumaugh to help him turn Jennifer over to 

make sure she was breathing. Mumaugh assisted Judd. 

¶ 10 Detective Todd Gordon and Officers Ronald Baudino and Thomas Rogel of the Marseilles 

Police Department subsequently arrived on the scene. A Marseilles ambulance also arrived, 

rendered aid, and took Jennifer to an area where she could be airlifted to a hospital. Judd then 

spoke to Courtney, who was sitting in Judd’s vehicle. Judd asked her what happened. Courtney 

told Judd that Jennifer was walking in the middle of the road, kicking a rock. Courtney also 

told others at the scene that Jennifer was walking in the middle of the road and provided a 

written statement to that effect. 

¶ 11 Officer Baudino asked Mumaugh if he had been drinking. Mumaugh responded that he had 

not and offered to take field sobriety tests. After administering field sobriety tests, Officer 

Baudino told Mumaugh that he was “good” and that he saw no signs of impairment. Mumaugh 

agreed to be taken by ambulance to OSF Hospital to give blood and urine samples. 

¶ 12 Detective Gordon and Officers Faber and Baudino did not detect any odor of cannabis on 

Mumaugh’s breath or clothing. At no time did they observe anything that would lead them to 

believe that Mumaugh was under the influence of drugs. Mumaugh did not show any signs of 

impairment in his actions or senses. Mumaugh told the officers that he had “smoked weed” 

five days earlier (on June 16, 2012) but had not smoked any marijuana on the day of the 

accident. 

¶ 13 While at the accident scene, Mumaugh realized that he had a “hitter” pipe in his vehicle, 

and he knew that the police would probably search the vehicle. To avoid being arrested for 

possession of the pipe, Mumaugh removed the pipe from the vehicle and discarded it on the 

side of the road. Mumaugh claimed he did not use the pipe to smoke cannabis at any time that 

day. He did not have any cannabis on his person or in his vehicle. Officer Rogel saw the hitter 

pipe (a type of pipe commonly used to smoke cannabis) on the ground next to the ambulance 

that took Mumaugh to the hospital. The pipe was not warm to the touch, and there was nothing 

Officer Rogel observed that would lead him to believe that the pipe had been used recently. 

Officer Rogel secured the pipe as evidence. Marseilles police officers thoroughly searched 

Mumaugh’s vehicle. They found no items of contraband or illegal substances. 
- 4 - 

¶ 14 Mumaugh told Officer Baudino and Detective Gordon that he was driving south on 

Highway 15 at about 50 miles per hour when he saw white legs walking on the side of the road. 

He then noticed a person in his lane. He swerved to the right and went into the ditch to avoid 

hitting the person, but he struck her with his car. 

¶ 15 Adam Diss, a certified accident reconstructionist for the La Salle County State’s 

Attorney’s Office, was dispatched to the accident scene. Based on his observations, Diss 

concluded that the crash occurred around the centerline of Highway 15. Mumaugh’s vehicle 

was traveling south on Highway 15 at approximately 50 miles per hour. Jennifer was walking 

south on the same road near the centerline when she was struck from behind by Mumaugh’s 

vehicle. There was damage to the left front fender and the left upper edge of the windshield of 

Mumaugh’s vehicle. The headlights were working properly. There was a large amount of 

change (which Jennifer had on her person at the time of impact) scattered across the 

northbound lane and some into the southbound lane of Highway 15. 

¶ 16 On October 10, 2012, Detective Gordon interviewed Mumaugh and asked him about the 

hitter pipe that was found on the side of the road at the accident scene. Mumaugh denied that it 

was his pipe. Detective Gordon collected a buccal swab from Mumaugh that day. A swab of 

the mouth area of the hitter pipe contained a mixture of DNA profiles from at least two people. 

A major DNA profile that was identified matched Mumaugh’s DNA profile. Additional 

forensic testing detected 0.2 grams of cannabis collected from the hitter pipe. A chemical 

analysis performed at the Illinois State Police Joliet Forensic Science Laboratory detected an 

undetermined quantity of tetrahydrocannabinol (THC) metabolite in Mumaugh’s urine.

¶ 17 Jennifer sustained serious injuries as a result of the accident, including an injury to her 

brain. She was in a coma for several months and suffered permanent disabilities. 

¶ 18 During the trial, the prosecutor argued that all he needed to prove was that Mumaugh was 

driving with cannabis in his system and that an accident occurred during which someone 

suffered great bodily harm. The prosecutor maintained that the time of day, the speed of 

Mumaugh’s vehicle, and the fact that Jennifer was walking in the middle of the road were 

irrelevant. Defense counsel argued, inter alia, that Mumaugh’s driving with THC in his system 

was not the proximate cause of Jennifer’s injury. The prosecutor responded that Mumaugh’s 

driving was a proximate cause of the accident because, (1) had Mumaugh not been driving, 

there would have been no accident and (2) it was “somewhat foreseeable” that the defendant 

could be involved in a motor vehicle accident while driving because accidents “occur all the 

time.” 

¶ 19 The trial court found Mumaugh guilty of aggravated DUI. The court noted that the 

evidence was to a large degree undisputed. The court found that Mumaugh was operating a 

motor vehicle on the highway at a time when cannabis was in his system and that an accident 

occurred between Mumaugh’s vehicle and a pedestrian that caused great bodily harm. 

Addressing the issue of proximate causation, the court stated that, in People v. Martin, 2011 IL 

109102, the Illinois Supreme Court “seem[ed] to say it doesn’t matter” and “seemed to not 

concern itself too much with that.” The trial court opined that “impairment doesn’t seem to be 

part of the offense here and intent doesn’t seem to be part. [sic]” 

¶ 20 Mumaugh filed a motion to reconsider and for judgment notwithstanding the verdict. He 

argued, inter alia, that the court’s reliance on Martin was misplaced and that the State had 

failed to prove proximate causation. 
- 5 - 

¶ 21 The trial court denied Mumaugh’s posttrial motions and sentenced him to two years’ 

imprisonment and one year of mandatory supervised release. The court stayed the sentence 

until the conclusion of appellate proceedings. Mumaugh filed his notice of appeal that same 

day. The next day, the trial court amended the judgment order to provide that Mumaugh’s 

sentence would be served at 85%. 

¶ 22 This appeal followed. 

¶ 23 ANALYSIS 

¶ 24 On appeal, Mumaugh argues that his conviction should be reversed for two reasons. First, 

Mumaugh contends that the 2012 version of the aggravated DUI statute under which he was 

convicted, a strict liability statute which allows for conviction upon proof of any amount of 

marijuana in the defendant’s blood without proof of impairment, violates substantive due 

process and is unconstitutional because it needlessly criminalizes innocent conduct and is 

therefore not rationally related to the statute’s purpose of keeping drug-impaired drivers off the 

road. Second, the State failed to present evidence sufficient to prove that the defendant’s 

driving was the proximate cause of the victim’s injuries, a required element of the offense of 

aggravated DUI (see 625 ILCS 5/11-501(d)(1)(C) (West 2012)). An appellate court “must 

avoid the adjudication of constitutional questions when a case can be decided on other 

grounds.” Marconi v. City of Joliet, 2013 IL App (3d) 110865, ¶ 16; see also People v. White, 

2011 IL 109689, ¶¶ 144-48; Innovative Modular Solutions v. Hazel Crest School District 

152.5, 2012 IL 112052, ¶ 38; People v. Jackson, 2013 IL 113986, ¶ 14 (“courts will address 

constitutional issues only as a last resort, relying whenever possible on nonconstitutional 

grounds to decide cases”). Accordingly, we will address Mumaugh’s proximate causation 

argument first. 

¶ 25 At the time of the accident at issue in this case, section 11-501(a)(6) of the Code provided, 

in pertinent part, that “[a] person shall not drive *** any vehicle within this State while *** 

there is any amount of a drug, substance, or compound in the person’s breath, blood, or urine 

resulting from the unlawful use or consumption of cannabis listed in the Cannabis Control 

Act.” (Emphasis added.) 625 ILCS 5/11-501(a)(6) (West 2012).3Section 11-501(a)(6) is a 

strict liability provision. A person may be convicted of violating this provision (which is a 

misdemeanor offense) if he is found to have any concentration of THC in his blood or urine, 

regardless of whether the level of THC was sufficient to impair the defendant’s driving. 

Martin, 2011 IL 109102; see also People v. Fate, 159 Ill. 2d 267, 270-71 (1994) (ruling that the 

statute “creates an absolute bar against driving a motor vehicle following the illegal ingestion 

of any cannabis or controlled substance” “without regard to physical impairment”). In fact, our 

supreme court has held that the statute presumes impairment. Martin, 2011 IL 109102, ¶ 23 

(“[T]he legal fiction of presumed impairment that we adopted in the context of driving with a 

 

3

Public Act 99-697, effective July 29, 2016, amended section 11-501(a)(6). The amended statute no 

longer criminalizes driving with any amount of a drug, substance, or compound in the person’s breath, 

blood, or urine resulting from the unlawful use or consumption of cannabis. It now criminalizes having 

a concentration of THC of 5 nanograms or more of delta-9-THC per milliliter of whole blood or 10 

nanograms or more of delta-9-THC per milliliter of other bodily substance within two hours of driving. 

See 625 ILCS 5/11-501(a)(6), 11-501.2(a) (West 2016). However, in this case, we shall apply and 

construe the prior version of the statute, which was in effect at the time of the accident. 
- 6 - 

blood-alcohol content over 0.10 applies with equal force in the context of drug driving.”); see 

also Fate, 159 Ill. 2d at 270; People v. Ziltz, 98 Ill. 2d 38 (1983). 

¶ 26 A person convicted of violating section 11-501(a)(6) is guilty of aggravated DUI if “the 

person in committing a violation of subsection (a) was involved in a motor vehicle accident 

that resulted in great bodily harm or permanent disability or disfigurement to another, when the 

violation was a proximate cause of the injuries.” 625 ILCS 5/11-501(d)(1)(C) (West 2012); see 

also Martin, 2011 IL 109102, ¶ 14 (“Section 11-501 sets forth the elements of a misdemeanor 

offense, then provides sentencing enhancements based upon the presence of other factors.”); 

People v. Quigley, 183 Ill. 2d 1, 10 (1998) (“[A]ggravated DUI occurs when an individual 

commits some form of misdemeanor DUI, in violation of paragraph (a), and other 

circumstances are present. The legislature added aggravating factors that change the 

misdemeanor DUI to a Class 4 felony.”); see also People v. Way, 2017 IL 120023, ¶ 21.4

¶ 27 To obtain a conviction for aggravated DUI, the State is not required to prove that the 

marijuana or other drug in the defendant’s system (or any impairment caused by such drug) 

was the proximate cause of the victim’s injuries; rather, it must merely prove beyond a 

reasonable doubt that the defendant’s driving was a proximate cause of his or her injuries. 

Martin, 2011 IL 109102, ¶¶ 20-28; see also Way, 2017 IL 120023, ¶ 25 (ruling that, when an 

aggravated DUI charge is based on a violation of a strict liability DUI provision that does not 

require proof of impairment, the aggravated DUI provision “requires a causal link only 

between the physical act of driving and” another person’s injury or death (internal quotation 

marks omitted)). However, proximate cause must be proven by the State in such cases; it is not 

simply presumed along with the presumption of impairment under section 5/11-501(a)(6). See 

Martin, 2011 IL 109102, ¶¶ 25, 28. 

¶ 28 Proximate causation consists of two elements: cause in fact and legal cause. People v. 

Hudson, 222 Ill. 2d 392, 401 (2006); First Springfield Bank & Trust v. Galman, 188 Ill. 2d 252, 

257-58 (1999). Cause in fact exists when a defendant’s conduct is a material element and a 

substantial factor in bringing about the injury. Galman, 188 Ill. 2d at 258; Lee v. Chicago 

Transit Authority, 152 Ill. 2d 432, 455 (1992). A defendant’s conduct is a material element and 

a substantial factor in bringing about an injury if, absent that conduct, the injury would not 

have occurred. Galman, 188 Ill. 2d at 258; Lee, 152 Ill. 2d at 455. “ ‘Legal cause,’ ” by 

contrast, is essentially a question of foreseeability. Galman, 188 Ill. 2d at 258; Lee, 152 Ill. 2d 

at 456. The relevant inquiry is whether the injury is of a type that a reasonable person would 

see as a likely result of his or her conduct. Galman, 188 Ill. 2d at 258; Lee, 152 Ill. 2d at 456. 

¶ 29 In proximate cause disputes, Illinois courts draw a distinction between a condition and a 

cause. Galman, 188 Ill. 2d at 257. “[I]f the negligence charged does nothing more than furnish 

a condition by which the injury is made possible, and that condition causes an injury by the 

subsequent, independent act of a third person, the creation of the condition is not the proximate 

cause of the injury.” Id. “The test that should be applied in all proximate cause cases is whether 

 

4Our supreme court has clarified that (1) “aggravated DUI is simply misdemeanor DUI with an 

aggravating factor, which turns the offense into a felony” (Martin, 2011 IL 109102, ¶ 24) and (2) 

“ ‘[t]he essential and underlying criminal act, however, remains the same: driving while under the 

influence. The physical injury caused to others by driving while under the influence produces the 

felony.’ ” Id. (quoting Quigley, 183 Ill. 2d at 10); see also Way, 2017 IL 120023, ¶ 21. 
- 7 - 

the first wrongdoer reasonably might have anticipated the intervening efficient cause as a 

natural and probable result of the first party’s own negligence.” Id. 

¶ 30 Applying these principles in Galman, our supreme court held that the defendant’s illegal 

parking of a tanker truck near an intersection was not the proximate cause of a pedestrian’s 

fatal injuries where, instead of crossing the street at the crosswalk (where the view of 

oncoming traffic was unobstructed), the pedestrian attempted to jaywalk across the street in the 

middle of the block, immediately in front of the parked tanker truck, where she could not have 

seen the oncoming traffic. Id. at 254-55, 259-62. The court found that the parked tanker truck 

was a cause in fact of the pedestrian’s injuries because, had the truck not been parked illegally 

at that location, the pedestrian’s injuries almost certainly would not have occurred, as her view 

of the roadway would have been unobstructed. However, the court found that the truck was not 

the legal cause of the pedestrian’s injuries because the injury was not the type that a reasonable 

person would foresee as a likely result of his or her conduct. The court explained that the 

dispositive question was “whether it was reasonably foreseeable that violating a ‘no parking’ 

sign at mid-block would likely result in a pedestrian’s ignoring a marked crosswalk at the 

corner, walking to mid-block, and attempting to cross a designated truck route blindly and in 

clear violation of the law.” Id. at 261. The court concluded, “[c]learly, it would not.” The court 

found that the pedestrian’s decision to jaywalk, “while undeniably tragic and regrettable, was 

entirely of her own making.” Id. The court emphasized that the driver of the tanker truck 

“neither caused [the pedestrian] to make that decision, nor reasonably could have anticipated 

that decision as a likely consequence of [his] conduct.” Id. 

¶ 31 In Reuter v. Korb, 248 Ill. App. 3d 142 (1993), our appellate court reached a similar 

conclusion on facts markedly similar to those presented in this case. In Reuter, the defendant 

was driving south in a dark, rural area at approximately 11:25 p.m. when a pedestrian wearing 

dark clothing suddenly appeared in the center of the defendant’s lane. Less than one second 

later, the defendant’s vehicle struck the pedestrian. The defendant was traveling at the posted 

speed limit (45 miles per hour) at the time. Approximately five minutes before the accident, a 

motorist had reported to a police officer that he had to swerve to avoid hitting a pedestrian 

walking in the roadway in the same street. Id. at 146-47. Toxicology reports administered after 

the accident indicated that the pedestrian had a blood alcohol level of 0.298. Id. at 149. Our 

appellate court held that the evidence established that the proximate cause of the accident was 

the pedestrian’s own conduct because the pedestrian had violated the law and “was not in an 

area where defendant should have known or expected a pedestrian to be.” Id. at 153. 

¶ 32 Likewise, in this case, the State failed to prove beyond a reasonable doubt that Mumaugh’s 

driving was a proximate cause of Jennifer’s injuries. There was no evidence that Mumaugh 

committed any traffic violation or any negligent act at the time of the accident. He passed all 

field sobriety tests administered at the scene, and the officers who interacted with him did not 

smell cannabis on his breath or clothes and found no evidence of impairment.5 He was driving 

five miles per hour below the posted speed limit at the time of the accident, and there is no 

 

5The State notes that Mumaugh was carrying a “hitter” pipe in his car at the time of the accident. 

However, the pipe was not warm at the time the police found it on the accident scene, the police found 

nothing to suggest that it had been used recently, and nothing in the defendant’s car or on his person 

suggesting that he had been smoking marijuana shortly before the accident. Plus, as noted above, there 

was no evidence that the defendant was impaired at the time. 
- 8 - 

evidence that he was distracted or that he veered outside of the southbound lane of traffic at 

any point (other than during his attempt to avoid striking Jennifer, who was walking near the 

middle of the road and, according to Mumaugh, suddenly appeared directly in front of him in 

the southbound lane). Mumaugh’s headlights were working properly, and there was no 

evidence that he could have avoided hitting Jennifer, who appeared immediately in front of his 

car a split-second before he hit her. The parties stipulated that a car moving at 50 miles per 

hour travels more than 73 feet in one second. The State did not present evidence establishing 

that a nonimpaired driver traveling at that speed could have avoided hitting a pedestrian 

suddenly appearing directly in front of his vehicle. In sum, there is no evidence that Mumaugh 

did anything as far as his driving was concerned that could have foreseeably caused the 

accident. 

¶ 33 Moreover, like the pedestrians in Galman and Reuter, Jennifer performed an unforeseeable 

act that subjected her to extreme danger. Minutes before the accident, Milan Najdanovich 

drove past Courtney and Jennifer on the highway and called 911 to report that two little girls 

were walking on the blacktop road “wearing dark clothes” with no reflectors on. Najdanovich 

said “Honey, they’re goin’ to get hit *** I’m really afraid somebody’s gonna hit ’em or 

something.” Immediately after the accident, Courtney told Mumaugh that Jennifer was 

walking “on the road,” and that she kept telling her to get off the road. When Judd asked 

Courtney what had happened, Courtney told him that Jennifer was “walking in the middle of 

the road, kicking a rock.” She also told others at the accident scene that Jennifer was walking in 

the middle of the road. Immediately after the accident, Mumaugh told Officer Faber that 

Jennifer was walking in the middle of the road when he struck her. Moreover, after 

investigating the accident scene, Diss, the prosecution’s certified accident reconstructionist, 

concluded that (1) the crash occurred around the centerline of Highway 15, (2) Mumaugh’s 

vehicle was traveling south on Highway 15 at approximately 50 miles per hour, and 

(3) Jennifer was walking south on the same road near the centerline when she was struck from 

behind by Mumaugh’s vehicle.

¶ 34 In a stipulated pretrial statement, Courtney stated that, if she were called to testify, she 

would testify that Jennifer was “near the fog line” at the time of the accident, “not in the road.” 

This statement cannot establish proximate cause, however, for several reasons. First, it flatly 

contradicts multiple statements that Courtney made to several witnesses immediately after the 

accident, when her memory of the events in question was presumably clearer and she had no 

motivation to lie. It also contradicts Courtney’s own prior written statement and all the other 

evidence, including the conclusion of the State’s accident reconstructionist and Mumaugh’s 

statements to police immediately after the accident. Indeed, Courtney’s stipulated pretrial 

statement represents the only evidence suggesting that Jennifer might not have been walking 

near the center of the road (or in the southbound traffic lane) at the time of the accident. 

However, Courtney’s stipulated pretrial statement is not definitive because she did not clearly 

state that Jennifer was not within the traffic lane at the time of the accident. Instead, she stated 

that Jennifer was “near the fog line” and not “in the road.” She did not state that Jennifer was 

not “on the road.” Thus, Courtney’s pretrial statement could merely mean that, at the time of 

the accident, Jennifer was walking near the fog line within the roadway, which would still put 

her in danger of being hit by southbound traffic. 

¶ 35 The State does not attempt to distinguish Galman or Reuter in its brief on appeal. Instead, 

the State relies upon several cases wherein our supreme court or our appellate court upheld 
- 9 - 

convictions for aggravated DUI and found that the defendant’s driving was a proximate cause 

of the victim’s injuries or death. However, in each of these cases, there was evidence 

suggesting that the defendant driver did something illegal or improper that could have 

foreseeably caused the accident.6 The State correctly notes that, in order to be guilty of 

aggravated DUI, the defendant need only be a proximate cause of the accident, not the sole 

proximate cause, and that unexpected hazards appearing in the roadway do not negate the 

defendant’s responsibility as a matter of law. However, in this case, there was no evidence 

suggesting that the defendant’s driving was even a contributing proximate cause of Jennifer’s 

injuries (other than, perhaps, Courtney’s pretrial statement, which is problematic and 

inconclusive for the reasons stated above). All the other evidence suggests that Jennifer’s 

conduct was the sole proximate cause of her injuries. 

¶ 36 In sum, it is simply not foreseeable that a pedestrian would be walking in the middle of a 

dark, unlit, rural road at 10:30 p.m. on a moonless night wearing dark clothing and no 

reflectors. Nor would a reasonable person foresee that the accident in the case was the “likely 

result” of his conduct when he was driving normally (nonnegligently), below the posted speed 

limit with functioning headlights, and within his proper lane of traffic. Contrary to the State’s 

argument, the fact that “accidents occur all the time” does not render this particular accident 

foreseeable. The dispositive question is whether the defendant reasonably might have 

anticipated the accident as a “natural and probable result of [his] own negligence,” i.e., 

whether Jennifer’s injury was “of a type that a reasonable person would see as a likely result of 

his or her conduct.” Galman, 188 Ill. 2d at 257-58. That is clearly not the case here because 

there is no evidence that Mumaugh’s driving was improper in any way, and at the time of the 

accident, Jennifer was not in an area where the defendant should have known or expected a 

pedestrian to be. See Reuter, 248 Ill. App. 3d 142. 

¶ 37 We will reverse a conviction on the basis of insufficient evidence only where, viewing the 

evidence and all reasonable inferences therefrom in the light most favorable to the State, the 

evidence is so insubstantial that no rational trier of fact could find each element of the charged 

offense beyond a reasonable doubt. People v. Smith, 185 Ill. 2d 532, 541 (1999); People v. 

Collins, 106 Ill. 2d 237, 261 (1985); People v. Ford, 2015 IL App (3d) 130810, ¶ 17. This is 

such a case. Proximate cause is an element of the offense of aggravated DUI. 625 ILCS 

5/11-501(d)(1)(C) (West 2012); Martin, 2011 IL 109102, ¶¶ 25, 28; People v. Swift, 2016 IL 

App (3d) 140604, ¶ 30. Based on the stipulated evidence in this case, no rational trier of fact 

could find that element proven beyond a reasonable doubt. Thus, even applying the deferential 

Collins standard, the defendant’s conviction must be reversed.

¶ 38 After oral arguments in this case, we granted Mumaugh leave to submit our supreme 

court’s recent decision in Way as additional authority in support of his argument on appeal.

See Martin, 2011 IL 109102 (the defendant drove his vehicle across the centerline); People v. 

Merrick, 2012 IL App (3d) 100551 (the defendant’s blood alcohol content was 0.212 and the defendant 

conceded the element of causation); People v. Swift, 2016 IL App (3d) 140604 (the defendant had taken 

his eyes off the road at the time of the accident); People v. Cook, 2011 IL App (4th) 090875 (the 

defendant’s blood alcohol content was 0.109 to 0.119 at the time of the accident, which could have 

allowed the jury to infer that the defendant could have been more alert); People v. Ikerman, 2012 IL 

App (5th) 110299 (the defendant was drunk and speeding); People v. Merritt, 343 Ill. App. 3d 442 

(2003) (the defendant was intoxicated and speeding); People v. Johnson, 392 Ill. App. 3d 127 (2009) 

(the defendant was impaired and was street racing).

The State contends that Way undermines the defendant’s argument because it establishes that 

the defendant bears the burden of proving that the victim’s conduct was the sole proximate 

cause of her injuries. In Way, our supreme court held (inter alia) that the trial court erred in 

finding that a defendant charged with aggravated DUI was barred, as a matter of law, from 

“raising as an affirmative defense” that the traffic accident at issue was caused “solely and 

exclusively by a sudden unforeseeable medical condition that rendered her incapable of 

controlling her vehicle.” Way, 2017 IL 120023, ¶ 31. However, Way is distinguishable from 

this case in one important respect. In Way, it was undisputed that the State had “sufficient 

evidence to show that [the defendant] was at fault” in the accident. (Internal quotation marks 

omitted.) Id. ¶ 29 (defendant’s car had “crossed the centerline” and “collided head-on” with 

the victim’s vehicle (internal quotation marks omitted)). Thus, in Way, the State discharged its 

burden of proving that the defendant’s driving was a proximate cause of the victim’s injuries. 

In this case, by contrast, the State has not met its initial burden of proving that the defendant’s 

driving was a proximate cause of the accident. In any event, even assuming arguendo that 

Mumaugh bore the burden of proving that Jennifer’s conduct was the sole proximate cause of 

her injuries, Mumaugh has discharged that burden. 

¶ 39 Because we reverse the defendant’s conviction on the issue of proximate causation, we do 

not address the defendant’s alternative constitutional argument. See, e.g., Marconi, 2013 IL 

App (3d) 110865, ¶ 16 (ruling that an appellate court “must avoid the adjudication of 

constitutional questions when a case can be decided on other grounds”). 

¶ 40 CONCLUSION 

¶ 41 For the foregoing reasons, the judgment of the circuit court of La Salle County is reversed.
