William Thomas was found guilty of killing 28-year-old Aryanna Doyle in a burning trailer on Easter Sunday.

According to court records, Doyle met Thomas at a park on March 31, 2018. He had been seen lighting garbage on fire at the park. The pair left the park together and went to the abandoned trailer home.

The next morning, firefighters responded to a fire at an abandoned trailer in North Highlands. Firefighters found Doyle’s burned body inside the trailer. Surveillance footage showed Thomas leaving the burned trailer minutes after the fire department was called.

According to the District Attorney’s crime lab, Doyle was still alive when the fire started. Additionally, Thomas’ semen was found during Doyle’s autopsy.

Thomas had a prior strike conviction in 2003 for battery causing serious bodily injury.

He is due back in court on March 17 for sentencing.
