Des Moines officers were originally called to the 21400 block of 13th Avenue South at about 7 p.m. after getting reports of a man beating his brother over the head with some sort of tool.
When police and medics arrived, they found the victim and transported him to Harborview with head injuries. The man's brother was gone, but officers spotted him a short time later. When the man saw the police, he took off on foot.
Officers gave chase and a K9 unit from the Kent Police Department was called in to help track the man. The Kent officer and the K9 found the man on the Des Moines Creek Trail a short time later.
Police say the suspect stabbed the dog with a pocket knife in an effort to get away.
The suspect was taken to Highline Medical Center to be treated for dog bites. The K9, a German shepherd named Kato, was rushed to an emergency veterinary hospital. Police say he required emergency surgery but was stable and expected to be released from the vet Wednesday afternoon.
"The suspect's actions today could have easily resulted in deadly consequences. Incidents such as this remind us of how dangerous an officer's job can be and the risks we encounter every day," Detective Melanie Frazier said in a Tuesday night news release.
The suspect is expected to be booked into jail after he's released from the hospital.
