A Columbia man starts the appeal process to get out of a 40-year prison sentence now that another Columbia man says he alone committed the crime. Ryan Ferguson has been in prison since 2005 for the 2001 robbery, beating and strangulation death of Columbia daily tribune sports editor Kent Heitholt. Ferguson’s former friend now says that he committed the crime alone without Ryan. Chuck Erickson pleaded guilty in 2005 and testified against Ferguson. Erickson’s statements are included in a motion filed by Ferguson’s attorneys in the western district court of appeals.
