Banks in the Tri-Cities were sent an alert Wednesday to be on the lookout for a serial robbery suspect.
The notice went out through Kennewick police's merchant alert and a bank security alert system, said Mike Blatman, Kennewick police's crime prevention specialist.
The same robber is suspected of holding up two banks on the west side last week and a Bank of America in Moses Lake on Tuesday, Blatman said.
The Moses Lake bank was robbed around 1:30 p.m.
Never miss a local story.
The suspect also hit a Bank of American branch in Mount Vernon around 2:15 p.m. June 12 and a second bank on June 14, authorities said.
The robber is descried as being black, 40 to 50 years old, 6-foot-2 and 250 pounds. In the first robbery, he wore a black hooded sweatshirt with a blue baseball cap, jacket and black-framed glasses.
