Glendale police are looking for a third suspect in connection with two shootings, one of them fatal, at an apartment complex earlier this month.
Douglas Elliott, 50, who was working at the complex, died after he was shot Dec. 3.
Police arrested Theodore Montgomery, 18, and Abraham Ntiamoah, 15, Dec. 6 in connection with Elliott's death.
They were booked into jail on suspicion of first-degree murder and three other felony charges.
Police said Elliott was involved in a confrontation with three people that led to the shooting.
Police said the three suspects were involved in a separate non-fatal shooting earlier that night at the same apartment complex.
They were fleeing the scene when they were confronted by Elliott, police said.
