STOCKTON (CBS13) — Days after a woman who was found dead in what police call a “severe attack,” investigators are one step closer to finding her killer.

Mary Sellars, 57, was found inside her home last weekend, but one thing was missing from the crime scene, her black truck, which was found torched just five miles away on Tuesday.

Now, police are hoping evidence they’ll take from the scene will lead them to a murder suspect.

The glow from flames and smoke was caught on a surveillance camera outside of one neighbor’s house shows the side of the Black Sierra truck on fire.

Rosie Hernandez said, “I just saw the flames, super sky high.” She lives down the street and heard the explosion as she was coming home from work.

Another neighbor said, “I just heard a bunch of like, booming that blew up, like gunshots.”

Police had been searching Stockton for this truck, for days. It was stolen from Sellars’ house on Friday.

Stockton Police Joe Silva said, “We need to find this suspect and get him off the streets before he can hurt anyone else.”

Though the truck was torched, police say there is still evidence they can use to move this investigation forward. Investigators combed the neighborhood for witnesses and more surveillance video on Tuesday.

“We don’t have a motive for this homicide which is very concerning about this case, because she was severely attacked inside that home,” said Silva.

The suspect is still considered armed and dangerous.
