Five Forest Grove officers fired their weapons during an encounter with an off-duty Hillsboro officer that left a Washington County sheriff's deputy wounded, according to the Forest Grove Police Department.

Hillsboro Officer Timothy Cannon, 46, a veteran of the department, is accused of attempted aggravated murder, according to authorities. He is being held in the Washington County Jail with bail set at $250,000.

The five officers are on standard administrative leave, said Capt. Mike Herb, a Forest Grove police spokesman. Their names have not been released.

Herb said at least five Washington County deputies were also involved in the incident. He did not say how many shots were fired.

The sheriff's office has not said that police fired during the incident.

Herb on Monday said he doesn't know if Cannon fired at police. "We believe he was armed with a weapon," said Herb. He would not say what type of weapon.

On Sunday night, Herb said an officer was shot during a standoff. Herb said the suspect barricaded himself inside the home. The sheriff's office would not confirm that information Monday morning.

An unidentified Washington County sheriff's deputy who responded to a disturbance between Cannon and his wife at their home in the 1000 block of 37th Avenue was hurt. His injuries were described by authorities as non life-threatening.

Cannon's wife and 6-year-old daughter were not hurt. Hillsboro police say Cannon's wife called police to the residence at about 8:30 p.m. Sunday. Cannon was off-duty at the time.

Authorities Monday morning would not release specific details about what occurred inside the home. Washington County sheriff's deputies and Forest Grove police officers entered Cannon's home while responding to the disturbance. A gun was fired at some point while police were in the home and the deputy was injured.

"We're dealing with a situation following a very volatile domestic disturbance," Herb said.

Sgt. David Thompson, a sheriff's office spokesman, said detectives are still trying to piece together what occurred. He expected that investigators will remain at the scene all of Monday and likely Tuesday. Beaverton and Tigard detectives with the Washington County Major Crimes Team are leading the investigation.

Thompson said some members of the county's Tactical Negotiations Team responded to the incident.

Cannon, a patrol officer with Hillsboro police, received a 2012 Life Saving Award, according to the Oregon Peace Officers Association.

Lt. Mike Rouches, a spokesman for the Hillsboro Police Department, said the agency has no indication that Cannon has any history of domestic violence. He has no disciplinary record.

"We've not been in this situation," said Rouches, referring to the severity of the accusation against Cannon. "Obviously, he'll be placed on administrative leave."

Rouches said Hillsboro police will conduct an internal investigation after the criminal inquiry into Cannon is completed. Cannon most recently worked swing shift for the agency.

Washington County sheriff's officials have not identified the deputy who was wounded in the incident. The deputy and Cannon were both treated and released at the hospital.

Neighbors told The Oregonian Monday morning that they heard as many as 16 shots Sunday night, many in rapid succession. One neighbor reported hearing eight shots in rapid succession followed by another eight.

Herb said having five officers on leave significantly impacts Forest Grove police, which has a total of 20 officers. He said the agency will use "creative scheduling" so that residents will not see a gap in service levels.

"We'll get through it," he said.
