Shooting suspect Aaron Ybarra is led to a court hearing at a King County Jail courtroom Friday, June 6, 2014, in Seattle. Ybarra was arrested in the killing of a 19-year-old student and wounding of two other young people Thursday at Seattle Pacific University. Police say Jon Meis and other students subdued Ybarra until officers arrived and handcuffed him moments later. Meis, the 22-year-old building monitor, pepper-sprayed and tackled the gunman Thursday in Seattle Pacific University's Otto Miller Hall, likely preventing further carnage, according to police and university officials.

Seattle Pacific University shooting

Yahoo News

An attorney gave notice Monday that an insanity defense was being considered for a man charged with killing one student and wounding two others at a Seattle university.

The verbal disclosure came at a hearing where suspect Aaron Rey Ybarra pleaded not guilty to premeditated first-degree murder and other charges in King County Superior Court.

His defense attorney, Ramona Brandes, has not disputed accounts of the shooting. She maintains Ybarra suffers from mental illness and was unaware of his actions "until he heard a girl screaming." (AP)
