Police believe the same robber is responsible for about 20 holdups in the Seattle area since October from Renton to Everett.
He most recently hit an espresso stand on Saturday in Bothell. Authorities say the suspect walked up to the stand armed with a black handgun, demanding money.
The businesses robbed include a Baskin Robbins, Subway restaurants, various gas stations, and coffee stands.
The robber wears a hood, bandanna, and gloves. He is described as a white or Hispanic male between the ages of 23 and 27, with a stocky build, around 5’2″ to 5’6.”
Authorities believe the suspect may be working with someone who drives a getaway car.
