PARKLAND, Wash. -- A Lakewood officer who was mortally wounded managed to fire shots at the gunman who killed four officers at a coffee shop Sunday morning, authorities say.

"We believe there was a struggle, a commotion, a fight," said Ed Troyer of the Pierce County Sheriff's Office. "The evidence tells us now that a Lakewood police officer got some shots off.

Troyer said one of the officers struggled out the door and fired his gun at the attacker.

Troyer said if the gunman was hit, he would likely seek medical attention far from the area and claim the wound is from an accidental gunshot.

Troyer asked clinics and hospitals to report anyone who shows up with a gun wound.

"We hope the suspect was shot because that would tell us who it is," Troyer said.

Troyer said two of the officers were shot and killed as they sat at a table Sunday morning, working on their laptops. One was shot standing up. And the fourth fought with the gunman and made it outside and was able to get off some shots.
