Two men are being sought by Kennewick police for allegedly robbing a 31-year-old Kennewick man at gunpoint Sunday night.

The victim told police that he was robbed around 9:45 p.m. after meeting up with a woman he met on Facebook, Kennewick police said.

They apparently met at a motel on 27th Avenue, and when she arrived, he got into her car and they drove to a nearby church to smoke marijuana, police said.

The victim told police he is a medical marijuana user.

Two men approached him while he was in the car, and one pointed a revolver at him as the other punched him in the face, police said.

The men took the victim's backpack, wallet and cellphone.

The victim was able to get out of the car and run away. He said the woman he was with pulled up, he got in and she drove to 27th Avenue and Quillan Street.

He then grabbed her phone and called police as the two robbers followed, police said. The victim said he jumped out of the car and started running back to the motel and yelled at the suspects that he was calling 911, police said.

The men then jumped into an older brown or gold four-door vehicle, which officers later found unoccupied and towed.

The woman left in her car, police said.

The victim was able to positively identify one suspect and investigators have tentatively identified the second man. Police said the second suspect has warrants for his arrest and is believed to be armed with a revolver.

The woman was contacted at her Burbank home and taken to the police station for questioning.

No arrests had been made as of Monday afternoon.
