ST. LOUIS • Jamyha Luss was at a friend’s house Sunday afternoon when two boys stopped to visit. One of them had a gun.

It’s unclear what happened next, but police say Jamyha, 14, was fatally shot in the back. Both of the boys fled the home in the Wells-Goodfellow neighborhood before police arrived.

St. Louis police continued their investigation on Monday, identifying as a person of interest a boy, 14, who turned himself in to authorities Monday afternoon.

At this point, investigators believe the shooting was accidental, according to a police source.

Jamyha was a student at Gateway Middle School and lived most of her life with her grandmother Shirley Wright and her four siblings because her parents are incarcerated. She lived in the 5500 block of Palm Street, less than a mile from the friend’s home where she was shot.

Jamyha went over to her friend’s house on Friday to spend the weekend there, Wright said. Jamyha was close with the friend and spent a lot of time at her house. The home is near Martin Luther King Drive and Union Boulevard, in the 5300 block of Patton Avenue.
