MOUNT PLEASANT, MI -- The 19-year-old accused of fatally shooting his mother and father in his Central Michigan University dorm has been found incompetent to stand trial, according to his attorney.

James E. Davis Jr. was found incompetent to stand trial March 23, according to his court-appointed attorney, Joshua Blanchard. Davis will now undergo treatment in an attempt to have him regain competency.

Davis is charged with two counts of open murder related to the March 2 shooting deaths of his parents, James Davis Sr. and Diva Davis. Open murder includes both first- and second-degree murder.

He was also charged with one count of felony firearm.

Davis' parents were helping him move out for spring break March 2 when he's accused of taking his father's pistol from the family vehicle, returning to his fourth-floor room at Campbell Hall and shot both his parents dead.

Police said Davis Jr. then fled Campbell Hall along railroad tracks and, after a 15-hour manhunt, was found a little more than a half mile away and taken into custody.

Police officials have not disclosed a suspected motivation for the double slaying.

The night before the shooting, Davis Jr. exhibited erratic behavior that police suspected was drug-induced, officials previously said. He was taken to an area hospital, where his parents picked him up the morning of the shooting.
