Mark Le Roy Tyree Jr. was 15 when he was shot and killed on June 26, 2016, in the Westmont neighborhood of South Los Angeles. At about 8:26 p.m. Tyree was in the driveway of a friend’s home with a 14-year-old companion when a dark-colored sedan drove by and someone inside opened fire, striking Tyree multiple times. He was taken to a local hospital and pronounced dead at 9:07 p.m. with gunshot wounds to his arm and chest; his friend was not injured.

The vehicle was described as a dark, primer-gray sedan, possibly a Chevy, last seen heading east on West 92nd Street. Investigators have said the shooting may have been gang-related, though Tyree and his friend were not gang members. Witnesses were unable to identify the shooter or shooters, and no arrests have been announced. The Sheriff’s Department Homicide Bureau is asking anyone with information to contact Crime Stoppers.

If anyone knew Mark, saw the sedan that night, or has information that could help, please come forward.
