He is considered armed and dangerous, if you see him, steer clear but notify authorities.

Not only are Kennewick police searching for 27-year-old Eriberto "Robert" Valdez, but so are US Marshall officials.

Wanted Fugitive (Kennewick police)

He's wanted for a Federal probation violation. A known gang member, he reportedly goes by the name of "Monster."  A cash reward of up to $1,000 is available for information leading directly to his apprehension. Anyone with any information is asked to report it at 1-800-222-8477.

Officials did not specifically say if he's believed to be in the area, but since Kennewick police are assisting in the search, it's safe to say he's likely somewhere around the Tri-Cities.
