Albuquerque, New Mexico (CNN) — The teenager accused of gunning down his parents and three siblings in their New Mexico home had hoped to go on a killing spree and die in a shootout with police, investigators said Tuesday.
Nehemiah Griego, 15, will stand trial as an adult in the weekend killings, prosecutors announced. He was arrested Saturday night, after deputies found the bodies of his mother, father, brother and two of his sisters in their home on the outskirts of Albuquerque.
Griego told investigators that he was "frustrated with his mother" and hoped to end his spree "at a Walmart, with mass destruction," Bernalillo County Sheriff Dan Houston told reporters. The teen is scheduled to appear in court later Tuesday to face two counts of murder and three counts of child abuse resulting in death.
