Portland police think it's this guy:

47-year-old Erick Duane Johnson was identified through tips from the public after surveillance video and photos were released by investigators. Johnson has a parole violation warrant and there is probable cause to arrest him for Aggravated Theft in the First Degree.

Johnson is described as a white male, 5'7" tall, 185 pounds, short brown hair or bald, blue eyes. Johnson rode away from the store riding a dark-colored mountain bike.

This investigation started on Tuesday July 24, 2012, at 1:55 p.m., when Portland Police officers assigned to East Precinct responded to the report of two guns stolen from Movie Madness, located at 4320 Southeast Belmont Street.

Officers contacted the shop owner who told police that a man came into the shop at approximately 1:15 p.m. and stole two guns used by actors John Wayne and William Holden.

As the Man himself once said, "You can tell him to his face, you can spit in his eye, you can make him eat sand out of the road, you can shoot him in the foot and I'll hold him for you -- but first we gotta catch him."
