During the investigation, police found that Mott hadn't shown up to Sandalwood High School that Monday or Tuesday.

According to the medical examiner's report, the last time French was known to be alive was on Nov. 21 at 2 p.m. when she spoke with her doctor’s office on the phone to confirm an appointment.
Co-workers told police they had spoken with French earlier that day and she had sounded groggy.
On Nov 24, police said they found French buried in a shallow grave in the backyard.
The police report said her body had been wrapped in thick clear plastic and secured with duct tape and masking tape.

The Border Patrol officer said he noticed a Pennsylvania tag attached to the car driven by Mott, but did not observe an inspection sticker attached to the front windshield, as required.
The officer said Mott first told him he had left his wallet in a hotel room, but eventually provided his name and birth date, which showed he had an active auto theft warrant.
The report said three firearms were located in the cab of the vehicle and all were loaded with live ammunition.
Once French’s autopsy results came back, an arrest warrant for murder was obtained Nov. 28.
