Police said they found one victim, a 16-year-old, who had been shot in the parking lot of the store.
While officers were working on that call, they got a second call that a 15-year-old male with a gunshot wound was in front of a home on the street just north of the scene.
Investigators said the victim was meeting with three suspects for a drug transaction when the suspects attempted to rob him. A physical altercation occurred and the victim and suspects began shooting at each other, police said. Officers said the two uninjured suspects then fled the scene on foot in an unknown direction.
Police said the 16-year-old later died at the hospital.
Police later came out and identified that the 15 year old had died.
