Defendant-Appellant Victor Manuel Torres-Castro appeals from his convictions for possession of an unregistered firearm (sawed-off shotgun) (count 1), 26 U.S.C. §§ 5481, 5681(d) & 5871, and possession of a firearm by an illegal alien (count 2), 18 U.S.C. §§ 922(g)(5) & 924(a)(2). He was tried before a jury, found guilty, and sentenced to concurrent 46 month terms of imprisonment and concurrent two-year terms of unsupervised release. On appeal, Mr. Torres-Castro contests the district court’s denial of his motion to suppress certain evidence and statements obtained by Albuquerque police officers at his home on December 4, 2004.
See United States v. Torres-Castro,
Background 1
On December 2, 2005, Albuquerque police encountered a fourteen-year-old girl running down Central Avenue in Albuquerque, New Mexico. The girl told police *995 that her boyfriend was twenty years old, that he had been chasing her, and that he had threatened to beat her. The police transported the girl to a police substation where she identified her boyfriend as Mr. Torres-Castro. She informed the police that Mr. Torres-Castro was an illegal alien who had been once deported, that she and Mr. Torres-Castro had engaged in sex, that he possessed a gun, that he had beaten her in the past and restrained her from leaving, and that he had threatened to shoot anyone who tried to take her away. While at the station, the girl identified a photograph of Mr. Torres-Castro, which allowed police to verify his age and familiarize themselves with his appearance. Later that night, the girl’s mother informed police that she was in the process of obtaining a restraining order against Mr. Torres-Castro.
Based on this information, police officers Dan Phel, Elder Guevara, and Mark Elriek decided to visit Mr. Torres-Castro’s home. They arrived at around 7:00 p.m. on December 4, 2004, intending to question him but not to arrest him. The officers had neither an arrest warrant nor a search warrant. Before arriving at the home, Officer Phel told Officers Guevara and El-rick that Mr. Torres-Castro had a gun and had engaged in domestic violence. As the officers approached the house, they identified Mr. Torres-Castro through a front window and noticed that several other individuals were seated in the front room. While the officers were looking through the window, one of the individuals in the home saw the officers and said something to the other individuals, whereupon some left the front room and moved elsewhere in the house.
Officer Phel then knocked on the front door, which Mr. Torres-Castro opened. The officers were uniformed but did not draw their weapons. Officer Phel asked permission for all officers to enter and talk to Mr. Torres-Castro. Mr. Torres-Castro agreed, and all three officers entered the house. Officer Phel began to question Mr. Torres-Castro about his relationship with his juvenile girlfriend. During this time, Officers Elriek and Guevara noticed that several individuals were in plain view in one or more back rooms. Officers Elriek and Guevara then conducted a brief protective sweep of the other rooms in the house and directed all individuals in the other rooms to return to the front room and be seated. None of the individuals or Mr. Torres-Castro objected and all individuals located in the home were assembled in the front room.
While conducting the protective sweep, Officer Elriek saw a box of shotgun shells in a clear plastic bag on a shelf in an open closet in a bedroom. Officer Elriek told the other officers about the shells but did not remove them. Officer Elriek remained near the bedroom door while the other officers spoke with the individuals in the front room.
Officer Guevara then asked each of the individuals if they had any weapons and if they would consent to a search of the residence. During this questioning, Officer Guevara specifically advised Mr. Torres-Castro in Spanish that he did not have to answer. Officer Guevara testified that officer safety issues prompted his questioning and that such safety issues arose after discovery of the shells and with the officers’ prior knowledge that Mr. Torres-Castro had a gun. R. Vol. III, at 44-45 (Tr. Feb. 5, 2005). Officer Phel testified that he did not intend to arrest Mr. Torres-Castro based on the discovery of the shells because he did not know it was illegal for him to possess them.
Officer Guevara eventually asked Mr. Torres-Castro, “Is there a shotgun in the house? Where is the shotgun at?” Mr. *996 Torres-Castro responded in Spanish that there was a shotgun located under a mattress in the bedroom where the shells were located, and he gave consent for the officers to search the house for weapons. The district court determined that such consent was voluntary under the totality of the circumstances. At some point, while the individuals were assembled in the front room, the officers conducted a pat-down search of each male for weapons.
Officer Guevara located the shotgun in the bedroom and noticed that it appeared to be an illegal sawed-off shotgun. About five minutes elapsed from the officers’ entry into the home until their discovery of the shotgun. Because the officers knew it was illegal for Mr. Torres-Castro to possess a sawed-off shotgun, they notified Agent Francisco Ortega of the Bureau of Alcohol, Tobacco, and Firearms (ATF), who arrived at the house shortly thereafter. Before Agent Ortega arrived, Officer Phel moved Mr. Torres-Castro to the bedroom where the gun was located and attempted to question him. Mr. Torres-Castro was uncooperative and Officer Phel handcuffed him. At that time, Officer Phel arrested Mr. Torres-Castro for possessing an illegal weapon and for charges relating to the mistreatment of his girlfriend. When Agent Ortega arrived at the house, he gave Mr. Torres-Castro Miranda warnings. Thereafter, Mr. Torres-Castro made incriminating statements.
Mr. Torres-Castro moved to suppress the evidence found in his house and any statements he made to the officers. The district court denied the motion after an evidentiary hearing. It first held that the protective sweep performed by the officers violated the Fourth Amendment because the sweep was not performed incident to an arrest. Notwithstanding, it found that the protective sweep did not taint any subsequently obtained evidence or statements. The district court reasoned that the officers had probable cause to arrest Mr. Torres-Castro and question him about weapons based upon independent sources prior to the protective sweep. It further held that Mr. Torres-Castro voluntarily admitted the officers to his home, consented to a search of the residence, and voluntarily made incriminating statements.
Discussion
A. Protective Sweep
In
Maryland v. Buie,
Following
Buie,
we held that such “protective sweeps” are only permitted incident to an arrest.
See United States v. Davis,
Mr. Torres-Castro argues that any expansion of the protective sweep doctrine is unjustified because the doctrine is premised on the assumption that an arrest is confrontational by its very nature. Mr. Torres-Castro argues that expanding the doctrine will encourage law enforcement to gain legal entry through “knock and talk” requests and then gather evidence without any requirement of suspicion or compliance with the Fourth Amendment. We recognize that a majority of circuits have extended the protective sweep doctrine to cases where officers possess a reasonable suspicion that their safety is at risk, even in the absence of an. arrest.
See, e.g., United States v. Martins,
We appear to be joined by only the Eighth Circuit and perhaps one panel of the Ninth Circuit, although there also appears to be an intra-circuit conflict, in our belief that a protective sweep must be performed incident to an arrest.
See United States v. Waldner,
Even under our precedent, however, a search may precede an arrest and still be incident to that arrest.
See Rawlings v. Kentucky,
The time at which an officer forms the intent to arrest is not determinative.
Anchondo,
The primary factor for determining whether a search is incident to an arrest is the time between the search and the actual arrest.
See Anchondo,
In this case, the officers had sufficient probable cause to arrest Mr. Torres-Castro prior to their entry into his home based on his alleged abusive conduct toward his juvenile girlfriend. Furthermore, the officers possessed the reasonable suspicion needed to support their protective sweep as required by
Buie.
Reasonable suspicion may arise when officers know an occupant has a weapon, has threatened to use it in an unlawful manner, and may be present in the residence.
United States v. King,
Furthermore, the officers did not know the identities of the other individuals in the house, let alone their relationship to Mr. Torres-Castro. The officers observed several individuals retreat into the back rooms of the house as they approached.
*999
Given the nature of Mr. Torres-Castro’s threats to use a weapon, and the behavior of the other individuals in the home, we think a “reasonable officer would take precautions to make sure that no hidden threat was lurking in the house.”
See United States v. Hauk,
The government does not argue that the district court's analysis was incorrect; rather, it argues that the court should reconsider its position that a protective sweep may only be performed incident to arrest and that this protective sweep would be justified under the expanded view of Buie. Aplee. Br. at 12-15, 18. Given the government’s position on appeal, and because we hold below that the protective sweep was not the “but for” cause for the seizure of certain evidence, and that other evidence would have been inevitably discovered, we need not resolve the question of whether the protective sweep was incident to Mr. Torres-Castro’s arrest.
B. Shotgun Shells, Shotgun and Admission of the Shotgun’s Location
For evidence to be suppressed, Mr. Torres-Castro must first demonstrate that his Fourth Amendment rights were violated.
United States v. Nava-Ramirez,
“But for” causality is a necessary, but not a sufficient, requirement for suppression.
Hudson v. Michigan,
— U.S. -,
With respect to the shotgun and his various statements made to the police, we conclude that Mr. Torres-Castro has not established a factual nexus between the protective sweep and that evidence. While there may be a factual nexus between the protective sweep and discovery of the shotgun shells, it is apparent from the district court’s factual findings that the shells would have been inevitably discover *1000 ed and, accordingly, should not be subject to suppression.
Those factual findings plainly support the conclusion that Mr. Torres-Castro voluntarily admitted the officers to his home. The statements from the girlfriend (involving domestic abuse and a gun) furnished a strong objective basis for the officers to ask Mr. Torres-Castro about the presence of a gun and to request permission to search his home for it. Likewise, having seen several individuals move from the front room deeper into the home, we think a reasonable officer would have asked the same questions and made the same request regardless of a protective sweep. Even if the officers were actually motivated to question Mr. Torres-Castro about the gun because they discovered shells during the protective sweep, their subjective motivations are irrelevant because the Fourth Amendment turns on the objective reasonableness of the circumstances.
See United States v. Carson,
Mr. Torres-Castro argues that because he knew the officers discovered shotgun shells during the protective sweep, this knowledge was “instrumental in his consenting to the search for the shotgun,” because he knew “the police had discovered potentially incriminating evidence.” Aplt. Br. at 38. He relies on
United States v. Ward,
There does appear to be a factual nexus between the protective sweep and discovery of the shotgun shells. After all, the shells were located by Officer Elrick while he conducted the sweep. Regardless of this causal connection, however, the shells should not be suppressed because they would have been inevitably discovered. They were located in a clear plastic bag in an open closet in the bedroom where the shotgun was located. Because they were in plain view, the officers would have discovered the shells during their search for the shotgun, which we have already concluded would have occurred regardless of the protective sweep. Thus, the doctrine of inevitable discovery excepts the tainted shells from suppression.
See Nava-Ra
*1001
mirez,
C. Post-Arrest Statements
Mr. Torres-Castro also argues that incriminating statements made after his formal arrest and
Miranda
warnings should be suppressed as fruit of the protective sweep. These statements are subject to the same analysis as the earlier discovered evidence and Mr. Torres-Castro’s statement and consent to search for the shotgun.
See United States v. Maez,
We conclude that the statements made by Mr. Torres-Castro have no “but for” relationship to the protective sweep, for the same reasons his earlier statements relating to the shotgun lack such a relationship. In addition, Mr. Torres-Castro’s post-arrest statements were further distanced from the protective sweep by the additional five to ten minutes it took Agent Ortega to arrive at the house and begin interviewing Mr. Torres-Castro. Furthermore, by the time Agent Ortega began his questioning, Mr. Torres-Castro had twice been warned that he could refuse to answer questions, once by Officer Guevara, and once by Agent Ortega via a
Miranda
warning. A
Miranda
warning itself may be a significant intervening circumstance that can break any factual nexus between an illegal search and subsequent incriminating statement.
See Oregon v. Elstad,
AFFIRMED.
. Some facts were controverted and dependent on the district court's credibility determinations. When reviewing the denial of a motion to suppress, we view the facts in the light most favorable to the government and for clear error.
