A woman student arguing with her estranged husband was shot to death Thursday on the campus of Whatcom Community College.

The woman, identified as Krystal D. Way, 25, of Everson, was shot multiple times outside a classroom building at about 1 p.m. She died at the scene.

Her husband, Mark S. Way, 37, of Bellingham, was held for investigation of homicide, police Sgt. Tim Lintz said.

The couple had a history of domestic problems that police first became aware of in November 1994, Lintz said.

The two had been talking in a parking lot next to Krystal Way’s car for 15 minutes when the woman started running away, calling for help, police said.

Her killer fired a 9mm semiautomatic handgun and then fled across campus, police said.
