A judge sentenced him to 50 years in prison for murder and 12 months for child abandonment.
As part of the plea deal, 26-year-old Lisenby admitted to stabbing his 19-year-old live-in girlfriend, Amanda Engelhardt, and leaving their baby lying on the couch as he fled out of town.
After opening statements on Monday, witness Brandon Hoyle said on February 27th of last year that he and another witness, Kelly Stewart, who were friends of the victim, had gone to the house that morning and heard a bloodcurdling scream.
Stewart said Lisenby would not let them into the bedroom. Engelhardt's body was found in the couple's home by police-- just hours after the scream was heard. Lanett Police indicated Engelhardt was nearly decapitated.
The couple's baby girl was 8-months-old at the time of the murder. She was found by police uninjured and wrapped in a blanket on a sofa.
Police say Lisenby fled to Mobile, AL where he was arrested a few days later.
