PER CURIAM 

[¶1.] A “concerned citizen” eyewitness told a police officer that he had seen 

two men drinking beer in a van parked next to the eyewitness in a parking lot. The 

police officer executed a traffic stop on the van after it was driven out of the parking 

lot. As a result of this stop, Shane Allen Satter was convicted of violating SDCL 32-

23-1, driving a vehicle while having 0.08 percent or more BAC. Satter appeals his 

conviction, claiming that the eyewitness’s tip did not create reasonable suspicion to 

conduct the traffic stop and, therefore, violated the Fourth Amendment of the 

United States Constitution. He argues that all of the evidence seized from this stop 

should have been excluded from trial. 

FACTS 

[¶2.] Officer Brian Warwick, of the Sioux Falls Police Department, was 

parked at the fire station at Madison and Kiwanis Avenues when a white pickup, 

bearing the logos of a Rapid City business, drove up to his patrol car. Officer 

Warwick rolled down his window, expecting that the out-of-town driver needed 

directions. 

[¶3.] The pickup driver told Officer Warwick that, while he was parked at 

the gas station across the street, a van had parked next to him in front of the 

convenience store. The citizen stated that the two occupants of the van were 

drinking beer from open containers, had the beer between their legs, and one of 

them had gone into the convenience store to purchase more beer. Officer Warwick 

asked the citizen to identify which vehicle he was referring to, and the citizen 

pointed to a van, which was clearly visible from Officer Warwick’s position. 
#24992

[¶4.] Within seconds of this identification, the van backed away from the 

convenience store, then left the parking lot. Officer Warwick was unable to obtain 

identifying information from the citizen before he left to follow the van. He followed 

the van for two blocks, saw no unsafe or erratic driving, but still executed a traffic 

stop on the van. The events that followed the traffic stop are irrelevant to this 

appeal. 

[¶5.] Satter was charged with Driving Under the Influence. Before trial, 

Satter sought to suppress evidence seized after the traffic stop, alleging a violation 

of the Fourth Amendment. The circuit court admitted the evidence, finding that 

reasonable suspicion had been established from the citizen’s statements. 

ISSUE 

Whether the information from the tipster alone provided reasonable 

suspicion to conduct a traffic stop in this situation. 

[¶6.] Satter argues that the unidentified citizen’s statements did not have 

sufficient “indicia of reliability” to justify the stop because the police officer “did not 

corroborate any of the tipster’s information and conducted the traffic stop based 

solely on the informant’s tip.” Further, because no identifying information was 

collected from the citizen, Satter contends that “there is no way to assess the 

reputation of the tipster or hold this person accountable should the allegations turn 

out to be untrue,” and thus, the tip should be considered unreliable. Finally, Satter 

argues that the tip regarded an open container violation, not that the driver of the 

vehicle was impaired; therefore, public policy concerns about the dangers of drivers 

under the influence are not applicable when the police officer, in following up on the 

tip, did not observe impaired driving.

The Fourth Amendment to the United States Constitution 

protects citizens from unreasonable searches and seizures. 

Although this protection generally requires probable cause to 

search, the requisite level of suspicion necessary to effectuate 

the stop of a vehicle is not equivalent to probable cause 

necessary for an arrest or a search warrant. All that is required 

is that the police officer has a reasonable suspicion to stop an 

automobile. Therefore, the factual basis needed to support a 

traffic stop is minimal. 

While the stop may not be the product of mere whim, caprice or 

idol [sic] curiosity, it is enough that the stop is based upon 

specific and articulable facts which taken together with rational 

inferences from those facts, reasonably warrant [the] intrusion. 

State v. Scholl, 2004 SD 85, ¶6, 684 NW2d 83, 85 (quoting State v. Chavez, 2003 SD 

93, ¶¶15-16, 668 NW2d 89, 95) (emphasis added). 

An informant’s tip may carry sufficient ‘indicia of reliability’ to 

justify a [vehicle] stop even though it fails to rise to the level of 

the probable cause needed for an arrest or search warrant. All 

that is required is that the stop be not the product of mere 

whim, caprice, or idle curiosity. 

Id. (quoting State v. Olhausen, 1998 SD 120, ¶7, 587 NW2d 715, 717-718). “The 

ultimate determination of the existence of a reasonable suspicion to stop a vehicle is 

a question of law reviewed de novo.” Id. (citing State v. Faulks, 2001 SD 115, ¶8, 

633 NW2d 613, 617). 

Reasonable Suspicion – Indicia of Reliability 

[¶7.] “Whether an anonymous tip suffices to give rise to reasonable 

suspicion depends on both the quantity of information it conveys as well as the 

quality, or degree of reliability, of that information, viewed under the totality of the 

circumstances.” Scholl, 2004 SD 85, ¶9, 684 NW2d at 86 (quoting United States v. 

Wheat, 278 F3d 722, 726 (8thCir 2001)) (emphasis original and added).

Anonymity 

[¶8.] This case presents a somewhat different factual scenario than previous 

tipster cases considered by this Court and the United States Supreme Court. These 

previous decisions have dealt with tipsters who make an anonymous telephone call 

to the police. The tips are then dispatched to a patrol officer. In this case, the 

tipster made direct, face-to-face contact with the patrol officer. 

[¶9.] The United States Supreme Court has not ruled on the distinction 

between face-to-face and telephonic tips or the effect this difference may have on the 

reliability of the tip. However, the distinction has been anticipated. 

If an informant places his anonymity at risk, a court can 

consider this factor in weighing the reliability of the tip. An 

instance where a tip might be considered anonymous but 

nevertheless sufficiently reliable to justify a proportionate police 

response may be when an unnamed person driving a car the 

police officer later describes stops for a moment and, face to face, 

informs the police that criminal activity is occurring. 

Florida v. J.L., 529 US 266, 276, 120 SCt 1375, 1381, 146 LEd2d 254, (2000) 

(Kennedy, J., concurring). 

Many cases have recognized the difference between in-person 

informants and anonymous calls. See, e.g., Florida v. J.L., 529 

US 266, 276, 120 SCt 1375, 146 LEd2d 254 (2000) (Kennedy, J., 

concurring); Davis v. United States, 759 A2d 665 (DCApp 2000) 

(police officer had probable cause for a search after citizen 

informant who declined to give his name flagged down the 

officer and told him a man nearby in a wheelchair was selling 

crack out of his right shoe); United States v. Salazar, 945 F2d 

47, 50-51 (2dCir 1991) (“[A] face-to-face informant must, as a 

general matter, be thought more reliable than an anonymous 

telephone tipster.”); United States v. Sierra-Hernandez, 581 F2d 

760, 763 (9thCir 1978) (“[A]lthough the informant did not 

identify himself by name, he would have been available for 

further questioning if the agent had judged the procedure 

appropriate. Unlike a person who makes an anonymous 
#24992 

- 5 -

 

telephone call, this informant confronted the agent directly.”); 

United States v. Gorin, 564 F2d 159, 161 (4thCir 1977) 

(“[S]tandards of reliability should not prevent appropriate action 

when a victim of a crime immediately has contacted the police. 

That same analysis applies [when a witness informs the police 

in person about a crime].”). . . 

United States v. Sanchez, 519 F3d 1208, 1214 (NM 2008) (emphasis added). 

[¶10.] The tipster in this case was not completely or “truly” anonymous. See 

Scholl, 2004 SD 85, ¶12 n4, 684 NW2d at 87 n4; Sanchez, 519 F3d at 1214 (“That 

the police understandably did not take the time to obtain [the tipster’s] personal 

information does not mean she was anonymous.”); United States v. Jenkins, 313 

F3d 549, 554 (10thCir 2002) (“A reasonable person . . . would realize that in all 

likelihood the police could, if they so chose, determine the person’s identity, and 

could hold him responsible if his allegations turned out to be fabricated.”). 

[¶11.] The unidentified tipster approached Officer Warwick in person. The 

white pickup truck he drove bore the identifying logos of a Rapid City business. 

While the police officer did not obtain the tipster’s identifying information and could 

not recall the name of the Rapid City business, the tipster made no effort to hide or 

conceal his identity.1

1. Satter’s arguments regarding the inability to hold an anonymous tipster 

accountable for potentially fabricated knowledge is inapplicable in the faceto-face context. Unlike the anonymous caller in United States v. Reaves, 512 

F3d 123, 127 (4thCir 2008), upon which Satter relies for this proposition, the 

unidentified tipster in this case did not “studiously avoid[ ] providing 

information that would have allowed her identity to be traced. . . .” Here the 

tipster was not anonymous, but simply unidentified. 
#24992

[¶12.] While the face-to-face tip situation has not been considered in this 

Court’s earlier tipster analyses, this is a relevant factor in the “totality of the 

circumstances” when assessing the reasonable suspicion necessary to conduct a 

vehicle stop. Because of the increased reliability of face-to-face tips, this factor 

weighs in favor of the officer’s reasonable suspicion. 

Quantity of Information 

[¶13.] In reviewing the quantity of information provided by a tip, both Scholl 

and Wheat considered a number of identifying facts provided by the tipster “such as 

the make and model of the vehicle, its license plate numbers . . . so that the officer, 

and the court, may be certain that the vehicle stopped is the same as the one 

identified by the [tipster].” Scholl, 2004 SD 85, ¶9, 684 NW2d at 86-87 (quoting 

Wheat, 278 F3d at 731) (emphasis added). In this case there was almost no danger 

of misidentification. The tipster identified the particular van by pointing directly at 

it, in the officer’s presence. In this situation, the tipster provided a sufficient 

quantity of information. 

Quality of Information or Degree of Reliability 

[¶14.] This Court has stated: 

With regard to assessing the quality or degree of reliability of an 

anonymous tip, the court observed that the “primary 

determinant of a tipster’s reliability is the basis of his 

knowledge” and further observed that “in erratic driving cases 

the basis of the tipster’s knowledge . . . [a]lmost always . . . 

comes from his eyewitness observations[.]” Wheat, 278 F3d at 

734. From this, the court concluded that, “an anonymous tip 

conveying a contemporaneous observation of criminal activity 

whose innocent details are corroborated is . . . credible[.]” Id. at 

735. 
#24992 

- 7 -

 

Scholl, 2004 SD 85, ¶10, 684 NW2d at 87. Furthermore, “[t]he time interval 

between receipt of the tip and location of the suspect vehicle [goes] principally to the 

question of reliability. . . .” Id. 2004 SD 85, ¶9, 684 NW2d at 87 (citing Wheat, 278 

F3d at 731). 

[¶15.] In the instant case, the tipster’s basis of knowledge came from his 

direct observation of the occupants of the van, while they were parked in the lot and 

in plain sight of any observer.2 The tipster immediately conveyed this information 

to the police officer. Because of the factual scenario, there were no innocent details 

left for the officer to corroborate. The only unknown facts were the elements of the 

violations, the possession of open containers and consumption of alcohol inside of 

the van. 

[¶16.] The exigency of the circumstances did not permit the officer to obtain 

further information from the tipster. The conversation lasted approximately twenty 

seconds, because the identified van started to leave the convenience store parking 

lot after that point. Once the van began moving, the potential danger resulting 

from the occupants’ consumption became more immediate. The tipster had relayed 

to the officer that he had witnessed the occupants drinking beer, not simply that 

they were in possession of open containers. Therefore, the officer faced a dilemma 

of either: 1) obtaining the tipster’s identifying information, then attempting to 

2. The tipster’s knowledge did not come from some special, insider knowledge of 

the violations; nor were his observations made while the vehicles were 

moving in traffic, potentially increasing the risk of misidentification of the 

containers or the beverages consumed. The observations were made in a 

public location, during daylight hours.

track down the van, driven by a potentially intoxicated driver, in city traffic; or 2) 

he could follow the van immediately. 

As to the risk that an anonymous tip might be a fiction intended 

to cause trouble for another motorist, the court determined that 

the risk of false tips is slight compared to the risk of not 

allowing the police to immediately conduct investigatory stops of 

potentially impaired drivers. In that regard, the court noted 

that erratic and possibly drunk drivers pose an imminent threat 

to public safety, that failure to stop them immediately risks 

sudden and potentially devastating accidents and, therefore, 

there is a substantial government interest in effecting such 

stops as quickly as possible. 

Scholl, 2004 SD 85, ¶10, 684 NW2d at 87. 

Signs of Intoxication 

[¶17.] Satter notes that neither the tipster nor the police officer observed the 

van driving in an erratic manner. Satter argues that there was no suggestion that 

the van or its occupants posed a risk to others. Therefore, he suggests “[t]his tip 

about open containers, standing alone, does not yield a reasonable suspicion that 

the driver was operating the vehicle under the influence, which takes away the 

public policy concerns about the dangers of drunk driving.” 

[¶18.] In Scholl, this Court observed: 

Courts have come to different conclusions as to the sufficiency of 

the cause for a vehicle stop based solely upon an informant’s 

observations of the non-driving behavior of a suspect. In State v. 

Miller, 510 NW2d 638 (ND 1994), the North Dakota Supreme 

Court invalidated a traffic stop based upon an informant’s report 

of a possible drunk driver who could “barely hold his head up” in 

the drive-up lane of a fast food restaurant. In Stewart v. State, 

22 SW3d 646 (TexApp 2000), the Texas Court of Appeals 

invalidated a stop based upon an informant’s report of an 

intoxicated driver at a convenience store who fell down twice 

while getting into his vehicle. However, in State v. Roberts, 293 

Mont 476, 977 P2d 974 (1999), the Montana Supreme Court 

upheld the validity of a stop based upon an informant’s report 
#24992 

- 9 -

 

that two men who had been fighting got into a pickup and that 

the driver was drunk because he could “barely walk.” 

2004 SD 85, ¶13, 684 NW2d at 88 (emphasis added). This Court went on to state, 

“We perceive a distinction between observations at a fast food restaurant such as in 

Miller . . . or at a convenience store as in Stewart . . . and observations at a bar 

where the likelihood of alcohol consumption is obviously enhanced.” Id. ¶14. 

However, the distinctions made among these locations are not necessarily relevant 

to the instant case. Focusing on the type of establishment is not necessarily 

conclusive. 

[¶19.] Satter’s argument neglects the particular behavior observed by the 

tipster. The tipster saw not only open containers, but also the consumption of beer 

from those containers. The tipster also stated that one of the occupants was 

purchasing more beer from this convenience store. The observed “non-driving 

behavior” was not simply sleepiness, stumbling, or a similar behavior that might be 

explained by any number of physical ailments. Here the tipster observed the act of 

drinking itself and the possibility of further consumption. 

[¶20.] To understate the point, like the bar in Scholl and unlike the 

convenience store in Stewart, in these circumstances “the likelihood of alcohol 

consumption is obviously enhanced.” In the totality of the circumstances, it was a 

simple, rational inference for the police officer to suspect that the van driver was 

intoxicated.3

 (continued . . .) 

3. It is irrational to suggest that an adult, licensed driver in this society is 

unaware that it is illegal to drink alcohol while driving, have open containers 
#24992 

- 10 -

CONCLUSION 

[¶21.] In the totality of these circumstances, given the increased reliability of 

face-to-face tips, the precise identification of the van, the strong basis of the tipster’s 

knowledge, the immediacy with which he reported his observations, the lack of facts 

left to corroborate, and the minimal intrusion of a vehicle stop on the occupants’ 

liberty compared to the potential, imminent threat of the observed behavior, this tip 

was sufficiently reliable to create reasonable suspicion.
