A serial bank robber identified with the help of the mother of his children after she recognized his distinctive tattoo - a dark blotch that covered her name at the request of another woman - has been sentenced to five years in federal prison.

Terrol Alan Casborn, 33, of Fairfield pleaded guilty in November to charges that he robbed the Mechanics Bank on Concord Avenue in Concord of $19,242 on Aug. 8, 2008. At a hearing Friday in Oakland, U.S. District Judge D. Lowell Jensen sentenced him to five years in prison.
