A Clackamas County jail deputy was arrested Thursday on suspicion of strangling his ex-girlfriend early this year, deputies say.

The Clackamas County Sheriff’s Office said it arrested Brandon Kearns, a 34-year-old Oregon City resident, on suspicion of felony strangulation. The arrest came after an agency supervisor learned Tuesday night of separate allegations of recent domestic violence.

The alleged strangling happened in Clackamas County in January, according to the sheriff’s office.

The alleged, undescribed domestic violence happened during a recent trip to Las Vegas, deputies said.

Both alleged incidents involve Kearns’ former girlfriend, deputies said. Both alleged incidents remain under investigation.

Kearns was placed on administrative leave Wednesday, deputies said, and a criminal probe was launched.

Deputies said Kearns has worked at the Clackamas County Jail, where he was booked Thursday, since 2008.

He was not featured on the jail’s online inmate roster Friday morning.

Once prosecutors file charges against him, his administrative leave will become unpaid, deputies said. That’s standard county policy.

Sheriff Craig Roberts issued a statement about the allegations late Thursday.

“We take all domestic violence allegations seriously,” he said. “These allegations are being swiftly and thoroughly investigated by our detectives, working with our partners at Milwaukie PD, the DA’s Office and in Las Vegas. I urge anyone impacted by domestic violence to contact A Safe Place Family Justice Center or Clackamas Women’s Services.”

A 24-hour Clackamas Women’s Services crisis and support line can be reached at 888-654-2288.
