Atlanta police have two more homicide cases on their desks Wednesday morning after two deadly shootings in the southwest corner of the city.

The killings Tuesday afternoon on Campbellton Road and early Wednesday morning on Woodrow Street bring the number of homicides the department has investigated this year to 148, the most since 152 in 2002.

The victim who died Tuesday afternoon was only discovered shot after being taken to a hospital. Atlanta police were initially called to the Cascade Glen Apartments on Campbellton Road to investigate a single-vehicle accident.

Officers arrived about 3:15 p.m. and learned the driver had already been taken to a hospital and died, according to police spokesman Officer Steve Avery. He was identified by the Fulton County Medical Examiner’s Office as 28-year-old Azal Lockett.

“At the hospital, it was discovered the victim had been shot,” Avery said in a statement. “Homicide detectives are working to determine the circumstances that led to the incident.”

Another shooting was reported about 3 a.m. Wednesday in the 800 block of Woodrow Street. A man’s body was found in the middle of the street, Avery said.

“The male had a gunshot wound to the chest,” he said.

He was later identified as 21-year-old Jason Sloan, according to the Fulton County Medical Examiner’s Office. His death is also under investigation, Avery said Wednesday, and police have not identified a suspect.

Including the latest incidents, at least 12 people have been killed in shootings in southwest Atlanta since the beginning of the month.

On Dec. 1, four men were killed in three separate shootings along Campbellton and Fairburn roads, and another was discovered dead Dec. 4 on Kimberly Road. Two days later, two men were discovered dead at a Sylvan Road gas station and a Delowe Drive day care.

Two more were killed in separate shootings Dec. 10 on Dimmock Street and Forsyth Street, although police have yet to classify the Forsyth Street incident as a homicide. On Sunday, a man died after being shot in the neck at a home on Cordova Street.

The incidents do not appear to be related. Anyone with information about any of the southwest Atlanta shootings is asked to contact police.
