Diana Pesserl, 31, was found dead inside her burning car behind the old Pine Lake Elementary School in West Bloomfield, Michigan, on December 9, 2016. An autopsy determined she died from a single gunshot wound to the abdomen. Reports say she had been sitting in her car listening to music that night.

Investigators focused on two young men who lived nearby. Eighteen-year-old DeSean Maurice Smith was identified as the primary suspect; he had been visiting 19-year-old Jaylen Steven Stringer the evening of the killing. Authorities say Smith left Stringer’s house, encountered Pesserl, and shot her. Police allege Smith then placed Pesserl in the trunk of her car, drove it to the school, and set the vehicle on fire. Detectives later recovered a .38 caliber pistol hidden in a heating vent at Stringer’s home.

Smith and Stringer were arrested. Smith was charged with open murder, arson, and felony firearm; a jury convicted him of first-degree felony murder, fourth-degree arson, and possession of a firearm in the commission of a felony, and he was sentenced to life without parole. Stringer pleaded guilty to tampering with evidence, received five years probation and 500 hours of community service after cooperating with investigators.
