Oklahoma man arrested for killing grandmother and in-law -- then beheading them

An Oklahoma man has been arrested on first-degree murder charges on suspicion of shooting his grandmother and her husband, and then cutting off their heads at their home, which is also used as a daycare center, police said on Wednesday.

Quinton Laster, 20, was arrested on Tuesday on charges of murdering Sharon Reed, 59, and her husband James Reed, 78, at their Oklahoma City home. There was no lawyer listed for Laster in an online arrest report.

Three small children were found unharmed in an attached covered garage that was being used for daycare. The children were removed from the scene and returned to their families, police said.

Police have not released a motive for the killings.
