Additional witnesses are suggesting the wrong man may be in prison for the past 31 years for the murder of a 16-year-old girl.  The testimony is a boost for inmate Daniel Harris, who maintains his innocence in the death of 16-year-old Kristina Nelson in Council Bluffs.  Harris wants a new trial.  Earlier this year, a man who was at a party with Nelson’s boyfriend on the night she was killed came forward.  He states that Nelson’s boyfriend and friend went to pick up Nelson, returned covered in blood, said they might have killed someone, talked of disposing a body and burnt their overalls in a barrel.  Three other party attendees have now signed affidavits consistent with these claims.  One stated seeing Nelson’s boyfriend struggling with a body in the trunk of a car.  Harris provided proof at his trial that he worked at Burger king that evening.  However, he was convicted based on an informant’s since-recanted testimony.
