The Malheur County Sheriff's Office is searching for a 23-year-old woman who is believed to have fatally stabbed a Payette man during an argument overnight. Ketra Savannah Siuce-Hale has been charged with first-degree manslaughter, and a bench warrant has been issued for her arrest.

"We're charging manslaughter based on the evidence gathered at this point. New information or evidence could lead to a change in the charging decision," said Erin Landis, chief deputy prosecutor in the Malheur County Prosecutor's Office. Mark Rogers, 26, was pronounced dead early Monday at St. Alphonsus Regional Medical Center in Boise.

Rogers was at a friend's house at 5017 Hyline Road in Ontario when a group of people he knew showed up at the residence and an argument ensued, Wolfe said. The sheriff's office received a 911 call about a stabbing at 12:38 a.m.

People at the house put Rogers in a car and rushed him to the hospital in Ontario. They were met by an ambulance en route. Paramedics then took Rogers to Saint Al's in Boise.

Wolfe said investigators are not release details on where Rogers was stabbed or how many times. He said he did not believe Rogers was threatening the woman verbally or physically before she stabbed him.

"We're still interviewing people," he said. "We still have quite a bit of work to do."

In Oregon, prosecutors must prove intent to get a conviction in murder cases.

Siuce-Hale was last seen driving a 2000 Jeep Grand Cherokee, blue in color with Idaho license plate “RIDSOLO.” Authorities are actively seeking any information about her location, but caution that she is considered armed and dangerous.
