 denial of his motion to suppress evidence seized during a warrantless search

of his home. Poe appeals the district court’s decision, and we affirm. 

I. BACKGROUND

On November 12, 2004, Officers Daniel Graham, Kane Northcutt and Bruce

Stafford of the Ozark Police Department, Ozark, Missouri, arrived at a residence to

investigate a report of a stolen vehicle. Upon their arrival, the officers observed a

vehicle parked in the grass behind the duplex and confirmed that the vehicle had been

reported stolen. Neighbors informed the officers that the resident was probably home

and that they had seen him transferring items from the back of the truck into the

duplex. Graham knocked at the front door of the residence and announced his

presence. There was no response. 

While Graham was knocking on the front door, Northcutt positioned himself

at the back door of the residence. With nothing impeding his ability to see through

the sliding glass door, Northcutt saw Poe looking out a front window at Graham.

Upon observing Poe, Northcutt knocked on the sliding door and ordered Poe to open

the door. Poe turned, looked at Northcutt and picked up a 12-gauge shotgun.

Northcutt yelled to Stafford that Poe had a firearm and attempted to radio that

information to Graham. 

At that point, after ten to fifteen minutes of knocking Graham heard yelling and

a commotion from behind the residence and static on his radio. Although aware that
-3-

Northcutt and Stafford were attempting to contact him, Graham could not discern

what they were saying. Graham told the spectators who were present to return to their

homes. Stafford ran towards the front of the duplex to tell Graham that Poe had a gun.

Although Graham saw Stafford come around the side of the duplex he did not hear

what Stafford was saying because, at that moment, Poe opened the door. According

to Graham, Poe did not say anything but rather stood back and looked at him. Graham

believed that Poe was giving himself up. Graham entered the home, handcuffed Poe

inside the front door and read him his Miranda rights. Poe did not verbally consent

or object to Graham’s entry. Rather, Graham testified that based upon Poe’s facial

expressions and actions he believed Poe to be indicating “this is over, come on in.”

(Jt. App. at 5.) After acknowledging that he understood his Miranda rights, Poe

waived those rights and told Graham that he was willing to talk and that someone had

brought the stolen truck to him. 

Upon entering the residence, Graham immediately observed a shotgun on an

end table approximately ten feet from the door. Prior to entering the residence,

Graham did not know that Poe possessed a firearm because Northcutt and Stafford had

not successfully conveyed that information. Graham asked Poe where the gun came

from, and Poe responded that the gun was from the stolen truck. Graham then asked

Poe if he was a felon, and Poe said yes. Upon searching Poe’s person, Graham found

keys to the stolen truck in a pocket. Poe was subsequently charged in a one-count

indictment with being a felon in possession of a firearm, in violation of 18 U.S.C. §

922(g)(1). 

In a motion to suppress, Poe argued that his Fourth Amendment rights were

violated when Graham entered and searched his residence without a warrant.

Following an evidentiary hearing, the magistrate judge determined that Graham had

probable cause to believe that illegal activity was occurring within the duplex and that

exigent circumstances existed to justify entering the home based upon Graham’s
-4-

concern for officer and public safety. The magistrate judge rejected as unpersuasive

Poe’s argument that Northcutt violated his Fourth Amendment rights when he looked

into the duplex through the sliding glass door. The district court adopted the report

and recommendation of the magistrate judge, and denied Poe’s motion to suppress.

On appeal, Poe argues that probable cause and exigent circumstances did not

exist to support Northcutt’s visual search of the duplex through the back door or

Graham’s entry into the residence. Poe further argues that because Northcutt’s

observation of the firearm was a result of a violation of his Fourth Amendment rights,

the exclusionary rule bars the use of Northcutt’s observation that Poe possessed a

firearm to support Graham’s subsequent warrantless entry. 

II. DISCUSSION

We review the district court’s factual determinations in support of its denial of

a motion to suppress for clear error and its legal conclusions de novo. United States

v. Solomon, 432 F.3d 824, 827 (8th Cir. 2005). The Fourth Amendment guarantees

the right of individuals “to be secure in their persons, houses, papers, and effects,

against unreasonable searches and seizures . . ..” U.S. Const. amend. IV. In

accordance with that guarantee, a warrantless search of a home must be supported by

consent or probable cause and exigent circumstances. Anderson v. Creighton, 483

U.S. 635, 641 (1987); Radloff v. City of Oelwein, 380 F.3d 344, 348 (8th Cir. 2004).

The Fourth Amendment draws a firm line at the threshold of a residence because “at

the very core of the Fourth Amendment stands the right of a man to retreat into his

own home and there be free from unreasonable governmental intrusion.” Payton v.

New York, 445 U.S. 573, 589-90 (1980) (internal quotations omitted). 
-5-

Probable cause exists when, “given the totality of the circumstances, a

reasonable person could believe there is a fair probability that contraband or evidence

of a crime would be found in a particular place.” Kleinholz v. United States, 339 F.3d

674, 676 (8th Cir. 2003) (internal quotations omitted). Exigent circumstances exist

if an objectively reasonable officer on the scene would have sufficient grounds to

believe an exigency existed. United States v. Schmidt, 403 F.3d 1009, 1013 (8th Cir.

2005). Although exigent circumstances typically involve a threatened life, imminent

escape of a suspect or the destruction of evidence, an exigency may also exist if there

is a “compelling need for official action and there is no time to secure a warrant.”

Radloff, 380 F.3d at 348 (citing Michigan v. Tyler, 436 U.S. 499, 509 (1978)). A

legitimate concern for officer safety or the safety of others may constitute an exigent

circumstance, and a warrantless entry into a residence may be justified if an officer

has a reasonable fear of harm. United States v. Hill, 430 F.3d 939, 941 (8th Cir.

2005). “Unexpected and dangerous events that arise during an arrest can create

exigent circumstances that justify law enforcement officers entering a residence in

order to protect themselves from any additional and unknown threats.” Id.

To the extent the government argues that Poe’s actions constituted implied

consent to Graham’s entry, we disagree. We examine the totality of the circumstances

to determine whether consent was voluntary or coerced. United States v. Smith, 973

F.2d 1374, 1376 (8th Cir. 1992). Although a person who opens a door in response to

a simple knock by officers knowingly exposes to the public that which can be seen

through the door, United States v. Deanda, 73 F.3d 825, 825-26 (8th Cir. 1996), we

have held that one who does so in response to a demand under color of authority does

not open the door voluntarily. United States v. Conner, 127 F.3d 663, 666 (8th Cir.

1997). Poe opened the door following over ten minutes of persistent knocks and

requests by Graham, officers were stationed at both doors of the duplex and Northcutt

had commanded Poe to open the door. A reasonable person in Poe’s situation would

have concluded that he had no choice but to acquiesce and open the door. See United

States v. Jerez, 108 F.3d 684, 692-93 (7th Cir. 1997) (no voluntary consent where
-6-

reasonable person would believe compliance with officers’ commands required).

Therefore, Poe’s actions did not constitute implied consent.

Poe contends that probable cause did not exist to support Graham’s search of

the residence because the officers had already located the object of their investigation,

the stolen vehicle. We disagree. The officers arrived at Poe’s residence in response

to a report of a stolen vehicle. Upon their arrival, Poe’s neighbors informed the

officers that he was home and that they had observed him transferring items from the

truck into the house. The officers could have reasonably believed that there was a fair

probability that Poe had removed contraband from the vehicle and taken it into the

residence. Therefore, probable cause existed to support a search of the duplex. 

Poe further argues that any belief that exigent circumstances existed is reliant

upon what Northcutt observed, an observation that he alleges was obtained through

unconstitutional means. However, Graham never became aware of what Northcutt

observed, and Northcutt’s observation is inapposite to the relevant inquiry, which is:

whether the facts and circumstances known by Graham at the time he entered the

duplex to arrest Poe were sufficient to cause a reasonable officer to believe an exigent

circumstance existed. See United States v. Cooper, 168 F.3d 336, 339 (8th Cir. 1999)

(proper inquiry considers facts and circumstances known to officer). 

The government argues that under the collective knowledge doctrine the

knowledge of Stafford and Northcutt that Poe possessed a firearm should be imputed

to Graham. We routinely look to the collective knowledge of all officers involved in

an investigation to determine whether probable cause exists provided there is some

degree of communication among the relevant officers. United States v. Horne, 4 F.3d

579, 585 (8th Cir. 1993). We have extended the collective knowledge doctrine to

impute knowledge in contexts other than probable cause when officers on a scene are

functioning as a team, rather than independent actors. See, e.g., United States v.
3

 Because Northcutt’s observation is not necessary to find an exigent

circumstance existed, we need not resolve Poe’s argument that Northcutt violated the

Fourth Amendment by looking into the duplex through the rear sliding glass door.

-7-

Terry, 400 F.3d 575, 581 (8th Cir. 2005) (knowledge of protective order); United

States v. Gillette, 245 F.3d 1032, 1034 (8th Cir. 2001) (knowledge of consent to

search); United States v. Wright, 641 F.2d 602, 606 (8th Cir. 1981) (knowledge of

prior felony conviction). The three officers undeniably acted as a team on March 23

and Stafford and Northcutt were in fact attempting to convey their knowledge to

Graham at the time he entered the duplex. For the reasons that follow, however, we

find that Graham could have legitimately been concerned for his safety and the safety

of others without knowing what Northcutt saw.3

 Therefore, we need not determine

whether an exigent circumstance justifying a warrantless entry can exist on the basis

of imputed knowledge. 

Graham testified that he was concerned for the safety of the neighbors who

were standing by as well as the officers present at the scene based upon the felonious

nature of the underlying offense and the subsequent commotion he heard. Following

Poe’s failure to open the door, Graham advised the neighbors who were present to

return to their homes. When Poe ultimately opened the door and stepped back,

Graham had been knocking and announcing his presence for over ten minutes.

Immediately prior to the door opening, Graham heard commotion coming from behind

the residence, yelling and static on his radio. Graham knew that the static was coming

from Northcutt. He contemporaneously became aware that Stafford was running to

the front of the house but did not hear what Stafford was saying because he was

focused on the opening door. Graham did not know who was in the home, whether

Poe or anybody else was armed, what had transpired behind the duplex to give rise to

the sudden commotion or what his colleagues were urgently attempting to tell him.

Under these circumstances, we find that Graham could have reasonably and

legitimately been concerned for his safety as well as the safety of others present at the
-8-

scene. Therefore, exigent circumstances existed to justify Graham’s limited entry into

the duplex to handcuff and arrest Poe.

 Under the plain view doctrine, an officer may seize an object without a

warrant if the officer did not violate the Fourth Amendment to arrive at the place from

which the object was in plain view, the object’s incriminating character was

immediately apparent and the officer had a lawful right of access to the object. United

States v. Collins, 321 F.3d 691, 694 (8th Cir. 2003). Because Graham did not violate

the Fourth Amendment by entering the duplex, he could lawfully seize the firearm,

as well as any other incriminating object, that was in plain view from the threshold of

the doorway. 

III. CONCLUSION

For the reasons stated, we affirm the district court’s denial of Poe’s motion to

suppress.
