A suspect has been charged with capital murder in the shooting death of a 30-year-old Birmingham man one week ago.

Police on Monday announced the arrest of 25-year-old Jamarian Carpenter. He is charged in the March 20 slaying of Devarta Dedre Thomas.

Carpenter is charged with capital murder because authorities believe Thomas was inside of a vehicle when he was fatally shot.

Carpenter was taken into custody by the Birmingham Police Department’s Crime Reduction Team. He was booked into the Jefferson County Jail just before 5 p.m. Friday and remains held without bond.

Thomas was found dead about 12:30 a.m. that Monday morning in the 300 block of 74th Street North. Officers responding to a call of a person down found him unresponsive in the roadway.

A motive has not been disclosed.

Thomas in 2016 pleaded guilty to the shooting death of his mother in Hoover.

Initially charged with murder, Thomas pleaded guilty to manslaughter in the shotgun slaying of 40-year-old Tawanda Thomas. Police at the time of her killing said the victim had gone to her son’s apartment to lecture him about ‘doing right.’

“She wanted him to get a job, stop using drugs and stop hanging out with some of the individuals he was hanging out with,’’ former Hoover police Capt. Gregg Rector said in 2016. “Basically, a mom lost her life while trying to convince her son to live a better, more productive life.”
