(CBS NEWS) JEFFERSON CITY, Mo. -- I'm Erin Moriarty. I have been covering Ryan Ferguson's case now for more than seven years. Ferguson was charged with killing a man named Kent Heitholt on Halloween night 2001.
From the beginning, there was just something not right about this case. There was plenty of physical evidence at the crime scene -- hair, fingerprints and bloody shoe prints -- but none of it matched him.
The entire case hinged on one troubled accuser: Charles Erickson.
Bit by bit, the case against Ferguson has fallen apart, and yet, his conviction has been upheld time and time again. This time, however, an unexpected development may make a difference.
For the first time, Ferguson's accuser spoke publicly ... and what a story he told.
