The suspect broke into a glass display case and stole a handgun from the downtown Puyallup Fred Meyer store on Thursday, police said.
The break-in was captured on store surveillance video.
The suspect appears to be a white male in his 20s, with collar-length shaggy brown hair and a beard, wearing a gray shirt, black shorts, tan shoes (skater style) with white laces and white soles. He was carrying a red-and-black backpack with a white logo at the top.
The suspect arrived and left on a mountain bike.
Anyone who recognizes the suspect or has any information about the case is asked to contact Detective Mike Lusk at 253-841-5521 or email him at firstname.lastname@example.org.
