Bruco Strong Eagle Eastwood entered his plea on Monday in Jefferson County District Court. He was ordered to undergo a mental evaluation at the state Mental Health Institute in Pueblo.
Mr. Eastwood faces 15 charges, including attempted first-degree murder in the Feb. 23 shootings outside Deer Creek Middle School in south suburban Denver.
Teachers tackled and restrained Mr. Eastwood until deputies arrived.
Defense attorneys have said they are investigating what role, if any, psychosis and mental illness played in the case.
Transgender woman held in bomb case
PAYETTE | A transgender woman who was at odds with police over how they acknowledged her gender identity in a 2007 traffic citation was arrested in the rigging of what appeared to be four pipe bombs to a propane tank at her home, the torching of her car and then allegedly running naked along a rural highway.
Catherine Carlson, 53, was arrested Sunday after firefighters responding to a report of a fire found pipes made to look like bombs on the porch of her trailer home in Payette, with a note warning of a booby-trap, authorities said.
About 50 homes were evacuated in the southwestern Idaho city when another call came in, reporting a car fire at a storage unit on U.S. Highway 95. The vehicle had been doused in gasoline.
Another call alerted police to a naked woman running down the highway, carrying what also appeared to be a pipe bomb. Police later learned the pipe contained legal documents, not explosives.
Ms. Carlson was being held in Payette County jail on suspicion of use of weapons of mass destruction, arson and indecent exposure.
