SEATTLE -- Gov. Chris Gregoire told KIRO 7 Eyewitness News that the escape of a criminally insane killer at a county fair is "embarrassing," and that "policy changes" to prevent anything like it from happening again are almost certain.

Gregoire spoke briefly with KIRO 7 reporter Chris Egert before her 2009 Life Sciences Summit at McCaw Hall in Seattle.

Gregoire said people could lose their jobs over the situation, but that she is waiting for a planned 15-day Department of Social and Health Services investigation to be complete before making any decisions.

Gregoire revealed that she has asked King County Prosecutor Dan Satterberg to assist in an open investigation into the case.

Phillip Arnold Paul disappeared into the crowd at the Spokane County Interstate Fair during a trip last week with 30 fellow patients.

Paul, 47, spent three days on the run before he was captured Sunday afternoon near Goldendale. Monday he was returned to Eastern State Hospital near Spokane.
