WBRZ - Baton Rouge

BATON ROUGE - A judge ruled today Dustin Musso is competent to stand trial for accusations he murdered his grandfather, setting the man's home on fire and stealing his car.

Psychiatrists testified today Musso was able to understand the charges against him and assist his attorneys. Other doctors also previously testified Musso was competent at hearings in January and in 2010.

Musso faces first-degree murder charges in the death of his grandfather, Peter Musso, in May 2009. Investigators said he set fire to the man's home to cover his crime, and he'd done time before for stealing a car from the same home.

An autopsy showed Musso suffered blunt force trauma to his head before dying of smoke inhalation.

A motions hearing is set for July 17, and the case is scheduled to go to trial Dec. 2.
