Christopher James Mejia, 14, was killed in a North Side shootout in San Antonio on February 21, 2022. The shooting took place outside a gas station near Blanco Road and West Mariposa Drive; Mejia was pronounced dead at the scene shortly after police answered a shots-fired call.

Authorities say the violence began as a planned robbery of an unnamed man’s narcotics. A green Suburban with five occupants was circling the gas station when one passenger stepped out with a gun and a struggle over a bag seen on surveillance footage preceded the shooting. A 17-year-old male passenger was critically wounded and taken to hospital; Enrique Bocanegra, 66, was also killed by a stray bullet while inside his home.

Four people have been charged with capital murder, including 21-year-old Oscar Martinez, 17-year-old Jerry Ortiz, and two other juveniles. What additional information about the sequence of events outside the SUV or the roles of those charged can readers share?
