Gunfire erupted in southwest Birmingham Sunday afternoon, leaving one person dead.

Birmingham police responded shortly after noon Sunday to University Crossings apartments, formerly known as Montevallo Gardens, in the Titusville community after Shot Spotter indicated multiple shots fired.

They found the teen unresponsive in the back parking lot of the complex. He was pronounced dead on the scene.

Officer Truman Fitzgerald said Shot Spotter registered at least 50 rounds fired in the following locations: 400 block of Gamma Street, 300 block of Iota Avenue, 200 block of Powell Avenue, Center Place South, First Avenue South and First Avenue S.W..

Those areas are all less than a mile away from where the teen was found dead, which is the 200 block of Third Avenue S.W.

Police have cordoned off most of the complex to help with crowd control. Friends and family members are arriving at the crime scene, obviously distraught.

Gunfire was reported in other areas nearby, according to police radio traffic.

This is the third time in the past year that these apartments have been the scene of a homicide probe.

The man is the 23rd person killed in a homicide this year in Birmingham.

Anyone with information is asked to call homicide detectives at 205-254-1764 or Crime Stoppers at 205-254-7777.

This is a developing story and will be updated as more information becomes available.
