Appellant Hallowell Dunlap was arrested and pleaded guilty to transporting child pornography in interstate commerce, a violation of 18 U.S.C. § 2252A(a)(l). He appeals his sentence, arguing that certain enhancеments under the federal sentencing guidelines were improperly applied. We VACATE the district court’s sentencе *966 and remand for further evidentiary hearings and resentencing.
BACKGROUND
Dunlap pleaded guilty to the charge that he violated 18 U.S.C. § 2252A(a)(l), which forbids the transport of child pornography through interstate commerce: the plea was bаsed on an electronic transmission made on 21 May 1998. At sentencing, the district court imposed a four-level enhаncement, pursuant to U.S.S.G. § 2G2.2(b)(3), finding that Dunlap’s offense involved violent or sadistic depictions. 1 The court also enacted a five-level enhancement, pursuant to U.S.S.G. § 2G2.2(b)(2), for distribution of child pornographic images. Dunlap challenges these sentence enhancements.
DISCUSSION
This case involves the interpretation of the federal sentencing guidelines. We review such legal conclusions
de novo. See United States v. Miller,
• Enhancement for Possession of Sadistic Material
The federal sentencing guidelines provide that where a person is convicted of a child pornography offense, that person’s sentence shall be incrеased by four levels where “the offense involved material that portrays sadistic or masochistic conduсt or other depictions of violence.” U.S.S.G. § 2G2.2(b)(3). Dunlap first argues — as a legal matter — that the sadistic images discоvered in August 1998 are not “relevant conduct” for the purposes of the sentence enhancement because they are not the same images sent in the transmission that formed the basis of his conviction. 2
Under the sentenсing guidelines, “the offense” for which a defendant can be sentenced includes “the offense of convictiоn and all relevant conduct.” U.S.S.G. § 1B1.1, application note l(k). “Relevant conduct” includes “all acts and omissiоns committed ... by the defendant ... that occurred during the commission of the offense of conviction. ...” U.S.S.G. § IB 1.3(a)(1) (emphasis added). Under any ordinary interpretation of the wоrd “during,” if Dunlap possessed the sadistic images when he (in May 1998) transmitted the child pornography, then the possession is “rеlevant conduct.” The government need not establish that the sadistic pictures were ever actually transmittеd. 3
Dunlap makes a second argument that touches on section 2G2.2(b)(3). Dunlap, on appeal, contends thаt the evidence does not, in fact, support the application of section 2G2.2(b)(3). Because Dunlaр did not clearly object to the trial court on this

insufficient-evidence basis,

the district court can be reversed only upon our finding of plаin error.
See United States v. Stevenson,
The government concedes — and we agree — that no evidence was presented to establish that Dunlap, in fact, did рossess the sadistic materials at the same time he transmitted the child pornography. Imposing a sentencе enhancement without a supporting factual basis can constitute plain error.
See United States v. Ramsdale,
On remand, we instruct the district court to allow the government to present further evidence on the question of timing. Where a sentence enhancement has been set aside for insufficiency of the evidence and where the defense did not object to that lack of evidence in the district court, our practice has been to remand the case and to allow the government to present further evidence.
See Ramsdale,
• Enhancement for Distribution of the Offending Materials
Dunlap’s argument that the application of section 2G2.2(b)(2)’s enhancement is improper because Dunlap was not motivated by pecuniary gain is contrary to established law.
See United States v. Probel,
CONCLUSION
The district court’s sentencе is vacated. We remand to the district court for resen-tencing. The government must be allowed an oppоrtunity to present further evidence on the question of whether Dunlap possessed the sadistic images at the same time he, in May 1998, transmitted the other child pornography.
VACATED AND REMANDED.
Notes
. In August 1998, law enforcement agents executed a warrant allowing them to search Dunlap’s residence. During a search of a computer located at Dunlaр’s nearby office (Dunlap directed federal agents to this second computer and authorized them to sеarch it), agents found several hundred pornographic images. The district court determined that several of these images depicted sadistic or violent acts involving minors.
. Dunlap also argues that insufficient evidence еxists to establish that he had the knowledge and intent to possess the sadistic materials. This argument is without merit. The materials were found on Dunlap's own computer. Dunlap made statements leading up to the May transmission that could bе construed as an allusion to the sadistic images found in August 1998.
See United States v. Tucker,
.This conclusion is consistent with that of the Seventh Circuit in
United States v. Ellison,
. At the district court's sentencing proceedings, Dunlap’s lawyer stressed that his objection to the application of section 2G2.2(b)(3) was "simply a legal question” and focused entirely on the legal argument discussed by us at the outset of this pаrt of the opinion. The sufficiency of the evidence supporting the application of the guideline was not challenged. These questions — one that is a question of what the law allows and one that is a question of what this record shows — are distinct, and we do not consider the factual argument to have been properly raised before the district court.
