A Portland man shot to death by his estranged girlfriend Wednesday thought she had committed suicide a couple weeks earlier, police said Thursday.

Suspect Jacqueline Kay Fielder, 30, fled the scene and drove to Redmond, Ore., where state police recognized her car as matching the suspect vehicle description from the Portland crime.

Pursued by police, the suspect drove through spike strips and eventually crashed.

"State, county and city officers attempted to stop the vehicle southbound on Highway 97... when it sped up to speeds near 100 mph... As it continued southbound, the suspect evaded several attempts to spike the vehicle's tires... As the vehicle drove through Terrebonne, it was involved in a minor sideswipe crash with a commercial truck when it passed the truck on the right shoulder and struck its left side and the guardrail," said Redmond Police Chief Ron Roberts.

The vehicle came to a stop at the intersection of Northwest Birch and 6th Avenue. The suspect jumped out of her car and ran, armed with a handgun, towards a car lot. Officers found her hiding behind a building and negotiated with her to surrender, but she put a gun to her head and pulled the trigger, said Sgt. Brian Schmautz, spokesman for the Portland Police Bureau.

Fielder was airlifted to a hospital with a critical head wound, police said. She later died.

The motive for the first shooting was not known, but police said there was a restraining order "between" the pair.
