The jury determined Owens strangled 91-year-old Doris Richardson in her Bide-a-wee Drive home in Huntsville in August 2011.
Prosecutors are seeking the death penalty for Owens.
WHNT News 19's Brian Lawson reports the penalty phase began this afternoon. The jury is being asked to recommend a sentence of life without parole or the death penalty. The hearing lasted about three hours Thursday and resumes in the morning.
Jurors heard the beginning of testimony from Dr. Marianne Rosenzweig, a Tuscaloosa-based psychologist, who did an evaluation of Owens and spent 12 hours interviewing him and 50 hours interviewing family members and friends.
During the trial, the defense argued a murderer has been walking the streets for more than four years, because Owens didn’t kill Richardson. Huntsville Police have said Owens admitted to burglarizing Richardson’s home, but claimed he did not kill her.
