Trial for man accused of Seattle university shooting begins

The trial of a man accused in a deadly 2014 shooting at Seattle Pacific University is underway.

The Seattle Times reports the trial of 29-year-old Aaron Ybarra began Monday with attorneys debating his mental state at the time of the incident.

Ybarra has pleaded not guilty by reason of insanity to first-degree murder and other charges in connection to the shooting that killed 19-year-old Paul Lee and wounded two others.

Charging papers say Ybarra scouted the campus before he returned on June 5, 2014, with the intent of committing a mass shooting he did not expect to survive.

The trial is expected to last up to two months.

Police have released surveillance video showing a man they say is Ybarra opening fire on the Seattle campus.
