Redmond City Manager Mike Patterson was arrested on Sunday on suspicion of assault and menacing at a Redmond home.

Patterson, who has been with the city since 2004, began two weeks vacation Monday, Redmond Mayor-elect George Endicott said Monday.

Rather than the Redmond Police Department handling the case, the Deschutes County Sheriff’s Office is investigating because Patterson, 41, is a Redmond city executive, according to Endicott. The Deschutes County district attorney has not yet filed charges.

“I know he has a personal situation, and it’s up to him to deal with it,” Endicott said. “It’s not a city issue. It’s a personal and private one.”

Endicott said he was not worried about the city’s management and how Patterson’s absence could affect it because Assistant City Manager Sharon Harris will act as city manager during Patterson’s leave.

Patterson told city leaders this morning that he would take time off, according to Endicott.

“He just said, ‘I’m going to take vacation and deal with this,’” Endicott said.

Patterson did not respond to two messages left on his cell phone.

Endicott and City Councilor Joe Mansfield both said the city leadership supported Patterson. They each mentioned that he had recently received a positive job review.

“It’s a shock to me, of course,” Mansfield said. “I’ve got to think the man is innocent until proven guilty.”

The victim reported the alleged assault — which reportedly occurred sometime before the weekend — at about 3 a.m. Sunday morning, according to Capt. Tim Edwards of the Sheriff’s Office. Patterson was not at the Redmond residence until later in the day. The Sheriff’s Office arrested him at about 8 p.m., Edwards said.

Patterson was arrested on suspicion of fourth-degree assault. That charge requires that the assault victim is either a relative or domestic partner and that the victim was injured. There was also at least one child present during the alleged assault, so the charge is elevated to a felony.

Patterson was also arrested on suspicion of menacing, a misdemeanor.

Edwards said he did not know if the victim sought treatment for any injuries.

Oregon state law requires that law enforcement officials make an arrest when there is evidence of a domestic assault.

The days making up Patterson’s two-week leave are paid vacation days that Patterson has accrued, according to Harris, also the human resources director for the city. She did not know whether or not Patterson had scheduled his days off before Monday.

“We’ve been trying to get him out on vacation,” Harris said. “If you don’t take it, you could lose some.”

According to Patterson’s contract, he can be fired for violating the city’s employee handbook. Employees can be fired for a number of reasons, without notice. One of those is being convicted of a crime involving “moral turpitude.”

Endicott said the city hadn’t considered that possibility.

“We haven’t gone that far yet,” Endicott said. “I mean, you know this happened yesterday. It’s just too hard to try and speculate what could possibly happen a month, six months, a year from now.”

Patterson was released on bail on Sunday. His trial date is set for Nov. 28, according to jail officials.
