Ayoola Adisa Ajayi was later charged with her murder after investigators found human bone and charred muscular tissue in his backyard, according to newly released search warrant affidavits.
A woman claims Ayoola Ajayi, the man accused of killing University of Utah student Mackenzie Lueck, sexually assaulted her last year during a dinner date.
As officials were investigating Ayoola Ajayi for the murder of the 23-year-old University of Utah student, they allegedly found images of girls aged 4 to 7 performing a sex act on a male on his computer.
Police said they recovered Mackenzie Lueck's body in a canyon miles away from where some of her charred remains were found in the backyard of her suspected killer, Ayoola A. Ajayi.
