It ended with a police shooting on a downtown street.

But it actually began as a life-saving effort by 911 responders a little more than a mile away.

Bainbridge Island Police Chief Matthew Hamner said Wednesday’s officer-involved shooting near Winslow Green followed an earlier emergency call near Ordway Elementary.

Hamner said Thursday that officers were called to the parking lot of the school on Madison Avenue after dispatchers received a 911 call of an overdose.

Police were the first to arrive, Hamner said, and found a woman on the ground and a man trying to revive her.

“They took over on chest compressions,” the chief said, and responders learned she had overdosed on drugs.

Once medics arrived, they took over the resuscitation efforts.

The woman didn’t appear to be breathing at first, Hamner said.

But a Bainbridge police officer who had been trained in using NARCAN, a drug used to treat opioid overdoses, grabbed a package of the nasal spray out of his patrol car and used it on the woman. It took two doses.

“There was a color change in her face — an ashen look — and it appeared she was not breathing,” Hamner said.

“He did the first one, and as soon as he did the second one, she was coming back,” the chief said.

“She did survive,” Hamner said. “We consider that a save.”

While the woman was being treated, however, her companion had gone back to sit in his Ford Mustang, parked at the edge of the parking lot at Ordway.

The situation took an unexpected turn as a police officer approached the vehicle, and the driver of the Mustang sped away, striking the officer as he drove off.

Hamner said it was a “glancing blow” that did not seriously injure the officer.

One of his fellow officers jumped into his patrol car and began pursuing the man down Madison Avenue.

The officer called off the pursuit, Hamner said, as the driver approached downtown.

A few minutes later, the man’s vehicle was successfully pinned in by a sheriff deputy’s car and another Bainbridge unit on Winslow Way in front of Eagle Harbor Congregational Church. He was shot after he repeatedly refused to follow the commands of officers who had surrounded his car, according to eyewitness videos of the incident.

Police have not identified the man, and Hamner said Thursday the shooting remains under investigation.

The Bremerton Police Department is conducting a review as an independent, outside agency.
