A Florida teenager accused of killing his grandmother pleaded not guilty in court Monday.
Police say 15-year-old Logan Mott shot and stabbed his grandmother, Kristina French, to death last month.
He then allegedly buried her body in his yard, stole her car, and drove to the Peace Bridge in Buffalo, where he was captured.
Police found a bloody knife and guns in the car.
Mott is charged with second-degree murder.
He is scheduled for a pre-trial hearing in January.
