The man charged with killing one student and seriously wounding two others on the campus of Seattle Pacific University on June 5 has pleaded not guilty.

On Monday attorneys for Aaron Rey Ybarra, 26, filed a notice of intent to pursue a not guilty by reason of insanity defense. The move doesn't mean they will go that route, just that they may use an insanity defense.

The gunman who allegedly killed a student on the campus of  Seattle Pacific University last week told police he had stopped taking his anti-depressant medicine because he wanted to "feel the hate."

That was among the revelations released in charging documents filed against Aaron Rey Ybarra in King County Superior Court on Tuesday.
