The suspected bank robber is a white man in his 40s or early 50s who is about 5 feet 7 inches or 5 feet 8 inches tall and has a medium build, the Federal Bureau of Investigation said.
He allegedly robbed two banks twice: Webster Bank on Cambridge Street in Boston on January 10 and February 10, and Eastern bank on Elm Street in Somerville on March 10 and July 24. During at least four of the robberies, he wore a hat and dark glasses, and during at least two he wore a wig or other hairpiece.
