PENDLETON, Ore. (AP) - A recently retired police dog for the Umatilla County Sheriff’s Office has died, and investigators are checking to see if poison is the cause.

Undersheriff Jim Littlefield said Wednesday that a veterinarian suspects the 9-year-old German shepherd named Yosh died from poisoning, but detectives still need hard evidence.

He says the Umatilla city police department will handle the investigation.

Yosh retired from the sheriff’s office last month and was living at the Umatilla home of the deputy who handled him during his career.

The sheriff’s office says Yosh faithfully served the department and played a key role in the capture of murder suspect Lukah Chang in August 2013. Chang was in the Pendleton Convention Center and surrendered moments after the dog entered the building and began barking.
