The teen facing murder charges in the stabbing deaths of an elderly Davis couple in April 2013 has entered a new plea claiming he was insane at the time of the attacks.
Daniel William Marsh, 17, pleaded not guilty by reason of insanity Monday at proceedings in Yolo Superior Court in Woodland, according to Yolo County District Attorney’s officials. He had earlier pleaded not guilty to the charges.
The new plea came two weeks before Marsh’s scheduled trial date on allegations of first-degree murder with special circumstances in the brutal April 13, 2013, slayings of local attorney and musician Oliver Northup, 87, and his wife, church official Claudia Maupin, 76, in their south Davis condominium.
Prosecutors say Marsh broke into the couple’s Cowell Boulevard condo, attacking the pair in their bedroom. Police later found Northup and Maupin during a welfare check.
Marsh remains held in Yolo County juvenile detention. Trial is scheduled for June 16.
