TUALATIN, Ore. -- A man who signed on to become a Clark County sheriff's deputy accidentally shot his wife to death in Tualatin on Sunday, according to police.

Police said Ryan Osbrink, 24, was practicing drawing his pistol from a holster when it unintentionally discharged as his wife, Kimberly Osbrink, entered the room.

A bullet struck Kimberly Osbrink in the stomach, police said. When emergency crews arrived, they said they found Ryan Osbrink administering first aid to his wife, who was rushed to Oregon Health & Science University.

Kimberly Osbrink later died at the hospital.

The gun used in the shooting was a .45-caliber semi-automatic pistol that Ryan Osbrink owned.

He had recently signed an offer of employment with the Clark County Sheriff's Office. His first day of work was to be Dec. 19, but his hiring has been delayed pending the outcome of the investigation.

According to an article in the Marine Corps News, Osbrink joined the Marine Corps to prepare for a career as a police officer and in hopes of joining a SWAT team.

In 2006, he received a Bronze Star Medal for courageous actions in Iraq.

The Tualatin Police Department is still investigating the shooting. Their findings will be forwarded to the Washington County District Attorney's Office for review.
