Detectives are investigating after one person was killed in a shooting in northwest Atlanta on Wednesday afternoon, police said.

A 911 call came in around 2:45 p.m. and police responded to the scene in the 800 block of Rock Street.

Two people were found in a vehicle in the parking lot of an apartment complex, Atlanta police spokesman Sgt. Greg Lyon said.

The driver was dead from a gunshot wound, while the passenger was suffering from injuries sustained when the vehicle crashed into a curb, he said. The survivor was transported to Grady Memorial Hospital in stable condition.

The investigation is continuing, and the motive remains unknown, Lyon said.
