FBI investigators say it appears as if the same man who robbed the U.S. Bank on Fairview Avenue Wednesday afternoon also robbed three other banks in the Treasure Valley since December.

The same man is also a suspect in the robbery of the Mountain America Credit Union in Cedar Drive, Utah, last month. The FBI says he robbed the Wells Fargo Bank on Five Mile and Ustick roads on Jan. 22; the Washington Trust Bank on State Street in Garden City on Jan. 4; and the Chase Bank on Federal Way in Boise on Dec. 21.

The FBI is working with police in Boise and Cedar City, Utah, on the case and is asking for public help in identifying the robber.

Boise police say the man was wearing a fake beard when he walked into the U.S. Bank at 10556 W. Fairview Ave. just after 4 p.m. and demanded cash from a teller, according to the Boise Police Department. The man did not show a weapon and left with an undisclosed amount of cash.

FBI officials say the man has not displayed a weapon during any of his five robberies. Sometimes he has made verbal threats, other times he has passed a note to a teller.

Witnesses in all five cases have described the robber as being between 50 to 60-years-old with grey hair. He is about 5 feet 10 inches tall and weighs between 145 to 180 pounds, according to FBI reports.

The clothes vary, but he has been seen wearing jeans and white sneakers and wore a green jacket in two of the robberies. He wears some kind of hat, including baseball caps or knit winter hat. FBI officials say he was wearing a blue jacket and fake beard during Wednesday’s robbery.

Anyone with information should call the FBI Salt Lake City Division at (801) 579-1400.
