The NY Post report explains that Coleman has not exactly been a smooth criminal throughout his career, but he's admirably decided to "make things right" with his conscience and his creator:
The guilt-ridden rapper who confessed to a 17-year-old murder told The Post yesterday he didn't know his victim had died when he decided to come clean on the cold case.
Trevell Coleman -- whose rap name is G-Dep -- said cops dropped the bombshell after he went into the 25th Precinct station house Wednesday to admit to the Oct. 19, 1993, shooting of John Henkel.
"I was surprised -- for some reason, I really didn't think that he died," the bald and bearded Coleman said in a jailhouse interview. "When they told me, I was like, 'Oh, I'm not going home after this.' "
Manhattan DA spokeswoman Erin Duggan said Coleman, 36, has now been charged with murder in the case. He faces life in prison.
