Nearly seven years after she was killed, police say that they've found the black man who killed Gina Gruenwald

Gruenwald's body was found on August 21, 2004 in the Capitol Hill area of Denver, Colorado. Friends had dropped her off after a night out and her body was found just four blocks away the following morning. She had been stabbed in the neck. The crime scene showed that Gruenwald had struggled with the person who killed her, including a bite mark made by the attacker. It's that bite mark, which left behind DNA, that led prosecutors to charge 42-year-old Billy Wilson. Wilson is said to be a homeless black man who was arrested earlier in 2011 on an unrelated case in San Francisco. A DNA sample obtained from Wilson was entered into a national database and was a match for Gruenwald's case. Wilson is now charged with murder in the case. He's expected to be returned to Denver in the coming weeks. Gruenwald was an all-state softball player at Bixby High School. She had just moved to Denver about a year before she was killed.
