Baby Face Nelson

In 1934 he returned to the Chicago area, where he hooked up with a gang led by the infamous John Dillinger. Later that year the FBI learned that Nelson, his wife and other members of the Dillinger gang were staying at a resort lodge in northern Wisconsin. They surrounded the lodge, but in the ensuing gun battle Nelson, Dillinger and other gangsters escaped. Nelson broke into a nearby house and took its occupants hostage. When FBI agents and local police checked the house, Nelson opened fire, killing one of the agents, then escaped. Not long afterwards the Dillinger gang, including Nelson, robbed a bank in South Bend, Indiana, killing a police officer. Later, in Chicago, Nelson killed two police officers who happened upon a meeting of the gang.

Lester Joseph Gillis, aka "Baby Face Nelson," began his crime career at an early age in a street gang in the Chicago slums. He was given the nickname "Baby Face" by his gang members because he looked much younger than he actually was (14). His specialties were car theft, bootlegging and armed robbery. He spent several years in prison on auto theft and bank robbery charges. In 1932, while being returned to prison from a trial for another bank robbery, he escaped custody and fled to California, where he hooked up with a bootlegging gang. Nelson traveled among California, Indiana and Minnesota, becoming involved in several murders.

Had the dubious reputation of being the only 1920s gangster to kill three FBI agents.
