The Alabama Court of Criminal Appeals Friday rejected 50-year-old Donald Broadnax's arguments to have his conviction and sentence overturned.
Broadnax claimed that his attorneys were ineffective.
Broadnax, who was 35 at the time of the slayings, was found guilty in the deaths of Hector Jan Stamps, 42, and her grandson DeAngelo.
Prosecutors say Broadnax beat them to death with a plank during an argument after he left a prison work-release program in Alexander City.
