Authorities say Christopher Johnson was pronounced dead at 6:25 p.m. local time Thursday after receiving a lethal injection at Holman prison in Atmore, the same community where the crime occurred.
Johnson, 38, was convicted in the death of his 6-month-old son, Elias Ocean Johnson. He testified at trial he beat and suffocated his son because he hated his wife and didn't want to be near the mother of their child.
Johnson was the sixth person executed in Alabama this year and the fourth to die since the state changed one of the drugs in its lethal injection from sodium thiopental to pentobarbital - owing to a nationwide shortage of sodium thiopental.
