CORVALLIS - The man accused of kidnapping two women during a police standoff last week was indicted Monday on an additional charge of attempted murder.

A Benton County grand jury handed up the indictment against William Scott Martin, 49, of Philomath in connection with the Aug. 4 kidnapping of both his estranged girlfriend and her elderly mother. That incident also brought Martin indictments on two counts of kidnapping, burglary and unlawful use of a weapon.

The indictment also added charges of harassment, telephonic harassment and criminal trespass in connection with incidents that occurred before the alleged kidnappings.

Oregon State Police and Philomath Police Chief Ken Elwer described the events leading to Monday's indictments this way:

At 12:53 a.m. on Aug. 4, Philomath police officer Grant Moser was dispatched to a burglary call at 245 S. 15th St., near Applegate Street in Philomath. He found a man armed with a handgun who was trying to force a woman into a pickup truck behind the house. The woman was identified as Kristy Seits, 51, who is Martin's ex-girlfriend. The attempted-murder charge was filed in connection with Martin's alleged actions against Seits.

The man with the gun was distracted by the arrival of police, and Seits was able to escape from him.

Moser fired at least one round and missed the man, who then ran into the house and reportedly took Kathleen Seits, 74, as his hostage. She is Kristy Seits' mother.

Officers from the Philomath Police Department, Benton County Sheriff's Office and the Corvallis Police Department rushed to the scene. They were soon joined by the Linn County Sheriff's Office SWAT team and hostage-negotiation team. The negotiator was able to talk the man into surrendering at 4:40 a.m.

Martin is being held at the Benton County jail on $1 million security in lieu of bail. His next appearance in open court has been scheduled for Aug. 20 at 1:20 p.m.

Following police protocol, Elwer requested that OSP detectives investigate the incident because Moser fired a shot. Moser is on administrative leave from the department, pending resolution of the investigation, which also is standard in cases where police fire a weapon.

Benton County District Attorney John Haroldson said he will review the OSP's investigation when it is complete.
