Authorities in Peru say van der Sloot later confessed to the crime.
Sources close to the investigation say the morning Flores was killed, van der Sloot left his room so he would be seen by hotel staff, reports CBS News Correspondent Elaine Quijano.
He was seen on hotel security video returning to the room, then exiting at 8:35, coffee cups in hand,
At 8:36, he's seen on the video looking around, and knocking meekly on the hotel room's door. He walks away, comes back a minute later and quickly looks up at the surveillance camera before walking out of view.
At 8:39, he's seen on the video returning again, this time with a porter, who opens the room's door for him.
"The fact of the matter is," says CBS News legal analyst Trent Copeland, "that he's clearly attempting to create some kind of ruse, some kind of subterfuge to suggest that he was not in the room at the time Miss Flores was killed."
CBS News has also obtained an Interpol document showing what van der Sloot told authorities in Chile when he was apprehended there.
It says van der Sloot turned himself in voluntarily, believing he would avoid Peruvian justice and be sent directly back to Aruba, where he remains the prime suspect in Alabama teen Natalee Holloway's 2005 disappearance.
On Monday, a Peruvian judge is slated to interrogate van der Sloot.
