A former Marion County Sheriff officer was indicted by a Marion County grand jury Friday on 25 counts including theft, misconduct and tampering with evidence between June 2014 and April 2018.

Sean Banks, 49, was arrested by the Salem Police Department June 27, 2018 on charges of theft of five firearms during a death investigation from October 2015.

The investigation of Banks was conducted by Salem Police and the Oregon Department of Justice.

Banks, of Keizer, is being held at the Linn County Jail on $200,000 bail. He is scheduled to appear March 13 in Marion County court.

According to a previous probable cause statement by Salem Police, Banks was on duty when he met a Keizer woman at the home of her recently deceased father in October 2015.

She told police she contacted Banks because her father had a number of guns at his house and she was uneasy about leaving them unsecured. He put the guns in his patrol vehicle and didn’t give her a receipt.

According to police, he sold or consigned five shotguns at Tick Licker Firearms in Salem and Rich’s Gun Shop in Donald.

Police learned Banks was involved in suspicious firearms transactions while investigating him for forgery.

The Marion County District Attorney’s Office said the subsequent investigation has uncovered additional criminal conduct.

Banks was placed on administrative leave by the Marion County Sheriff’s office July 12, 2018 after working for the department for five years.
