Even if you had a car without a cell connection, license plate readers and cameras make it easy for anyone with access to replay and reverse any traveling you do with any car.
This is basically how the prosecutor in the Idaho case is putting Kohberger at the scene. They've also used where his cell phone was pinging during the night of the murders as additional evidence he was there.
Meanwhile, detectives scoured video footage from cameras in the area and picked out a white Hyundai Elantra driving past the house three times before stopping on the fourth pass shortly after 4am. The car left 16 minutes later “at a high rate of speed”, according to Payne
Meanwhile, FBI investigators trawled through Kohberger’s cellphone records and discovered that he turned it off shortly before the attack, perhaps thinking it would help him to avoid detection. The phone springs to life again at 4.48am on a road out of Moscow.
The records also showed that Kohberger was in the area near the house at least a dozen times in the months before the attack, usually in the early morning or late evenings. Investigators said they were examining whether he “conducted surveillance on the King Road residents and was in contact with any of the victim’s associates before or after the alleged offense”.
