VANCOUVER, Wash. -- Authorities in Vancouver are looking for at least four men who attacked a 20-year-old man as he walked to work.

“I’m not safe,” said Josh Cooper. “I’m not invincible.”

Cooper was walking near the intersection of Northeast 110th Avenue and 26th Street Sunday night when a group of four white men asked him for marijuana. Cooper said no and ran away from the men, according to Vancouver police.

The victim was hit by an unknown object in the head as he was running and the men caught up to him and started punching his body and head.

“They hit me a few times and the last thing I remember is begging them to stop," Cooper said.

Cooper blacked out and when he came to he was several blocks away at a gas station. When things came into focus, he noticed his backpack was gone. Police said he walked a few blocks when someone noticed he was hurt and let him use their cell phone to call 911. Cooper was taken to a hospital.

“They wanted to watch potential bleeding into my brain from the head trauma,” he said.

There was none of that, but Cooper suffered a broken nose and a concussion.

“It makes it iffy walking,” he said. “I don’t want to walk anywhere anymore.”

Police say the suspects are white males in their 20s and they had a dark-colored vehicle.

The major crimes unit is investigating. Anyone with information is urged to contact the Vancouver police. If you would like to help with Cooper’s medical expenses you can do so by going to
