Police seek man accused of attacking his brother with samurai sword

A man accused of attacking his brother with a samurai sword is on the run. Oregon State Police (OSP) is asking for the public's help to find Preston Sweaney, 23. OSP dispatch received a call of a stabbing in the Grants Pass area early on Thursday morning. OSP troopers and detectives responded to the scene.

According to investigators, Sweaney got into a fight with his brother, Nathanial Sweaney, 21, inside a motorhome. Another relative, Christian Burnison, 18, was also there too. The fight turned physical between the siblings, and Preston Sweaney cut his brother's side and left arm with a samurai sword, OSP said.

Burnison also received a minor cut on his hand while trying to intervene. Paramedics took Nathanial Sweaney to Three Rivers Community Hospital in Grants pass for treatment. He's expected to recover. Preston Sweaney was last seen running away from the motorhome and should be considered dangerous, OSP said.

The suspect is described as 5'9" tall, 155 pounds, with hazel eyes and a scar on his chin. He has tattoos on his chest, right calf and shoulder. When he left the scene, he had a shaved head with a "Mohawk" strip, and was wearing blue jeans with white rear pocket stitching and no shirt, OSP said. A photograph released to the media shows his eyes crossed, but according to Curry County Sheriff's Office correction staff he does not have crossed eyes.
