A man was arrested in the shooting and decapitation of his grandmother and her husband at an Oklahoma City home where they operated a day care, police said Wednesday.

Quinton Dashawn Laster, 20, was arrested Tuesday after police found the bodies of Sharon Reed, 59, and James Earl Reed, 78, in the Oklahoma City home where the three lived, according to Sgt. Ashley Peters.

Peters said the couple operated an in-home day care at the property. The children were found unharmed in an attached garage and apparently did not see the crime, Peters said. She did not know the ages of the children.

She said Laster spoke to a neighbor after the crime, leading the neighbor to ask police to check on the couple.

"I’m not sure exactly what words were exchanged with the neighbor, but the neighbor called 911," Peters said.

Laster is being held on two complaints of first-degree murder, Peter said. She did not know whether he had an attorney.

Peters said investigators were still trying to determine a motive for the slayings and declined to say where in the home the victims were found.

"We are not able to release where they were located as the investigation is still open, and that’s of evidentiary value."

Peters said Laster was arrested in February 2015 for misdemeanor assault and battery and was arrested as a juvenile.
