A man was shot to death in a possible ambush at an east Birmingham home Wednesday.

Birmingham police responded just after 9:30 p.m. to a home in the 300 block of Killough Springs Road. That house is between Five Mile Road and Orchid Lane.

Authorities identified the victim as 36-year-old Tristian Jackson of Montgomery. The man believed to be a longtime military veteran was shot as he arrived at the home to visit a family member. The gunfire erupted in the garage area and the victim was able to make it inside before he collapsed in or near the living area.

The relative inside the home was not injured. “We don’t have a lot of information right now,’’ Sgt. Johnny Williams said, “but detectives are throughout the community trying to gather information.”

More than a dozen of Jackson’s family members and friends rushed to the scene, visibly upset by the crime. No suspects were in custody late Wednesday.

“Our main concern is trying to find out who exactly committed this crime,’’ Williams said. “We want people to come forward who may have information about what may have occurred here tonight.”

The slaying is Birmingham’s third homicide of 2020, all of which have taken place since Sunday evening. Anyone with information is asked to call Birmingham homicide detectives at 205-254-1764 or Crime Stoppers at 205-254-7777.
