OPINION
Defendant, Harold McRae, was convicted of possession with intent to distribute cocaine base, 21 U.S.C. § 841(a)(1); felon in possession of a firearm, 18 U.S.C. § 922(g); and using and carrying a firearm during a drug trafficking offense, 18 U.S.C. § 924(c). Defendant’s appeal challenges (1) the district court’s denial of his motion to suppress evidence on the grounds that he did not have “standing” to challenge a warrantless search because he did not have a legitimate expectation of privacy in the premises; 1 (2) the sufficiency of the evidence with respect to the offense of using and carrying a firearm during a drug trafficking offense; and (3) the imposition of a two-point enhancement to defendant’s offense level for obstruction of justice. For the reasons that follow, we vacate defendant’s sentence with respect to the enhancement and remand for resentencing. In all other respects, we affirm.
I.
On November 25,1995, Detroit Police Officers Chris Cole and James Fraser drove past a house at 1245 Eastlawn in Detroit, while on routine patrol, and saw a black female coming out of the front door. Officer Cole was familiar with the house, drove by it on patrol a couple of times per week, and knew that it had been vacant for the previous ten months. Before that, crack cocaine had been sold from the house for more than a year. Being so alerted, the officers returned an hour later and conducted surveillance of the house from down the street. Over the next 45 minutes, they observed six to eight people go into the house, stay only one or two minutes, and then leave.
The officers went up to the house. Officer Cole peered into the window and saw the defendant sitting on a couch. They announced themselves as the police, kicked open the front door, and saw defendant jump up and grab a rifle and a plastic bag. He ran to the kitchen, but was unable to get out the kitchen door. He ran down the basement stairs, threw the rifle behind the stairs, and dropped the plastic bag when Officer Cole caught up to him. The officers searched the house for other possible occupants but found none. Defendant was arrested and the officers seized the plastic bag, which contained 178 rocks of cocaine base, a loaded semi-automatic Russian SKS with a pistol grip, and $241 in cash.
Defendant was interviewed at the police station by ATF Special Agent Michael Yott at about 2:00 p.m. and, after signing a waiver of his Miranda rights, gave a written statement. That statement indicated in part that he had no address, the house on Eastlawn was vacant, and he had been living there about one week. McRae denied that the rifle was his and said it was in the house when he got there. Yet, he further stated that the rifle was “just there for protection.” McRae also denied knowing anything about the drugs.
Following an evidentiary hearing, the district court denied defendant’s motion to suppress evidence and statements, finding that (1) defendant did not have standing to contest the manner of entry into 1245 Eastlawn because he did not have a reasonable expectation of privacy in the premises and (2) the United States had met its burden of showing that no coercion was involved and that defendant’s statement was voluntary. Defendant testified at trial and the jury convicted him on all three counts. Defendant was sentenced to a term of 97 months imprisonment *711 on Counts I and II, to be followed by a term of 60 months imprisonment on Count III.
II.
A. Denial of Motion to Suppress
In reviewing the denial of a motion to suppress, we review the district court’s factual findings for clear error and its conclusions of law de novo.
United States v. Williams,
McRae never claimed that he owned or rented the house. Defendant’s written statement on the day he was arrested indicated in pertinent part:
When the police arrested me I was at 1245 Eastlawn, Detroit, MI. This house is vacant. I have been living at this house since I got back from California about 1 week ago. The house is vacant. I am the only person living in it.
The district court’s finding that the house was vacant was not clearly erroneous. Further, the district court properly concluded that McRae did not have a legitimate expectation of privacy by virtue of having stayed a week in the vacant premises that he did not own or rent. On appeal, defendant also relies on testimony presented during trial to support his claim. Such evidence, however, cannot be considered by this court because it was not offered at the suppression hearing and defendant did not renew the motion to suppress at trial.
United States v. Thomas,
While defendant cites two other cases to support his claim of a legitimate expectation of privacy, his reliance upon them is misplaced. In
United States v. Gooch,
*712 B. Sufficiency of the Evidence
Defendant contends that the evidence was not sufficient to support a conviction on the charge of using and carrying a firearm during a drug trafficking offense. On appeal, “the relevant question is whether, after reviewing the evidence in the light most favorable to the prosecution,
any
rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt.”
Jackson v. Virginia,
The Supreme Court recently addressed the scope of the “carrying” prong of § 924(c)(1) in
Muscarello v. United States,
— U.S. -,
To establish the remaining element of the offense, that the firearm was carried “during and in relation to” a drug trafficking crime, the evidence must support a finding that the firearm furthered the purpose or effect of the crime and that its presence or involvement was not the result of coincidence.
United States v. Riascos-Suarez,
C. Obstruction of Justice Enhancement
Defendant’s third claim on appeal is that the district court failed to make the necessary independent findings with respect to the perjury that was the basis of a two-point enhancement to his offense level for obstruction of justice. See United States Sentencing Commission, Guidelines Manual, § 3C1.1 (Nov.1997). We agree.
In
United States v. Dunnigan,
At sentencing, defense counsel objected to the probation department’s recommendation that the court find McRae had perjured himself with respect to several areas of his testimony. The district court overruled the objection, without specifying the areas of conflicting testimony or making independent findings with respect to either the elements or the factual predicates necessary for a finding of perjury. Nor is there any explanation of why the perjury was material. Although the government’s argument focused on defendant’s testimony concerning the firearm, the district court simply overruled defendant’s objection and enhanced the offense level by two points for obstruction of justice. The enhancement may not be affirmed on an inference that the ruling was based upon the government’s arguments.
Spears,
Accordingly, defendant’s sentence is VACATED with respect to the two-point enhancement under § 3C1.1 and the case is REMANDED for resentencing consistent with this opinion. Specifically, the district court is instructed to identify with particularity the intentionally false statements by McRae and articulate how those statements were material. In all other respects, the judgment of the district court is AFFIRMED.
Notes
. Although raised as an issue of "standing,” the question of whether a defendant may contest an allegedly illegal search collapses into the substantive issue of whether the defendant had a legitimate expectation of privacy.
United States
V.
Maddox,
. Even if we could consider the evidence presented at trial, we would still affirm the district court's ruling. Defendant emphasizes that there were blankets or curtains on some of the windows; furniture and a jacket in the house; and telephone service to the house. A minimal amount (.63 cents) of water was supplied to the house in the month of November and, although service had been disconnected in October, electricity was illegally supplied to the house after that date. The evidence at trial included testimony that the toilet was uprooted, that the water faucets did not work, and that the house was cold (a kerosene heater was sitting next to the television).
. While defendant alluded to the issue of volun-tariness in his statement of facts, he has not raised it as an issue on appeal. Thus, it is considered abandoned and is not reviewable.
See Boyd v. Ford Motor Co.,
. We note that the government bears some responsibility for the failure of the district court to make adequate findings on the record to support the enhancement it sought in this case. The United States Attorney either knew or should have known what findings were required to support the enhancement and had an obligation to ask that the district court make such findings at the time of sentencing.
