From the Chicago Tribune yesterday - scary stuff:

A man who once knocked out a woman’s teeth in the South Loop when she refused to give him a cigarette was arrested again this week when he threatened to kill a man while panhandling in the Uptown neighborhood, according to Chicago police.
Derrick King, 50, was cited by critics of the state’s early prison release program when he threatened a woman in 2009, a day after getting out of prison for the brutal attack against Jennifer Hall on her birthday in August 2008.
