Police in Santa Ana, Calif., are trying to identify a suspect in the shooting of two high school baseball players who were cousins.

Roberto Izelo, 18, and his 19-year-old cousin were sitting in a parked car in an alley when they were approached by a gunman, who was wearing dark clothing and a hoodie, around 7:30 p.m. on Thursday.

Officers arrived on the scene — about 2 miles from Century High School, where the victims attended — and found both teens suffering from apparent gunshot wounds to their upper torsos.

Both victims were transported to a local hospital where Izelo was pronounced deceased. His cousin was listed in stable condition.

A 16-year-old was sitting in the back seat of the vehicle but was unhurt, KTLA reported.

Santa Ana Police Sgt. Maria Lopez tells PEOPLE that the investigation has led authorities to believe the shooting was gang-related, though it's not clear why they were parked in the alley.

"We don't know what the motive was at this time," she says. "The detectives are still trying to piece together that portion of the investigation."
