'Good Grammar Bandit' robbing banks again, FBI says

The FBI says a bank robber dubbed the "Good Grammar Bandit" because his demand notes are perfectly typed, spelled and punctuated is suspected of hitting three more banks in the Denver area this month.

FBI spokesman Dave Joly says the man robbed the banks in Thornton and Westminster between July 6 and July 29. The man is suspected of hitting four banks in the Denver metro area in less than a week in April.

He is described as black, in his 30s and between 5-foot-7 and 5-foot-9 with a slender build.
