A man in his 50s is being treated in a Boise hospital for injuries he suffered after he refused deputies’ repeated orders to drop the rifle he was holding, officials said.

One Canyon County Sheriff’s deputy opened fire Sunday night, hitting the man at least once. No deputies were injured.

The Canyon County Critical Incident Task Force is investigating, which is standard procedure whenever a Canyon-area officer is involved in a shooting.

“It is my understanding his wounds are serious,” said Caldwell Police Chief Chris Allgood, whose agency is leading the investigation. Officials said they are not releasing the man’s name now because they haven’t made a decision about charging him with a crime.

Caldwell officers received medical clearance to interview the man Monday and are interviewing others with information about the case.

The officer who shot the man also will be interviewed, but Canyon County Sheriff’s Chief Deputy Kieran Donahue said standard practice is to give an officer who’s been involved in a deadly force incident 48 hours to rest and recover before questioning him. The deputy is on paid administrative leave, following standard policy.

Canyon County Sheriff's deputies have been involved in three nonfatal shootings since Jan. 17, 2012.

On Sunday night, a family member called the sheriff's office to the home in the 5700 block of Oak Street east of Nampa, saying the man was suicidal and had firearms, Allgood said. Deputies arrived at 8:45 p.m., talked to family members and asked the man to come out and talk to them, he said.

The man emerged from the house carrying a rifle and refused repeated commands to drop the weapon, Allgood said. Details on whether the man made threatening moves toward deputies were not available.

When a deputy opened fire, the man dropped the rifle, went back in the house and shut the door, Allgood said. A Canyon County SWAT and crisis negotiation team responded. After police had a short telephone conversation with the man, he came back out about 10:45 p.m. without a weapon and surrendered. He was treated at the scene and then taken to Saint Alphonsus Regional Medical Center, he said.

Numerous firearms were found inside the house, Donahue said.

Officials said they had no information that the man had threatened anyone inside his home, although he reportedly had been “tearing up the house.”

Various questions about the incident remain unanswered publicly, such as how many shots were fired or what specific injuries the man suffered.

Allgood and Donahue said the man does not appear to have a history with local police.

Donahue, who was elected to succeed retiring Sheriff Chris Smith and will be sworn in next Monday, said having three officer-involved shootings in slightly less than a year is unusual for the sheriff's office, but “it’s just by chance. They’ve all been very different.”

The task force is investigating the autumn shooting of Kyle Batt, who officials say wounded two deputies when he opened fire as they approached a home west of Caldwell Oct. 24. The deputies returned fire and wounded Batt, who faces federal firearm charges and, likely, local charges after the investigation concludes.

On Jan. 17, a Canyon County sheriff's deputy shot Michael Lance Davis, who investigators say threatened deputies with what turned out to be a fake gun at a home near Nampa’s Skyview High School. Davis pleaded guilty to felony aggravated assault and was sentenced to at least four years, and up to 20 years in prison.
