Prosecutors filed charges this week in the cold case murder of Gloria Dean Clay, who was found partially frozen and strangled to death on a set of railroad tracks in north Minneapolis in 1993.
Preston Arnold, 49, has been charged with second-degree murder, after investigators matched his DNA to a biological sample from Clay's fingernails taken shortly after the murder.
An autopsy revealed that Clay had been physically and sexually assaulted before she was found dead on the railroad tracks on March 19, 1993.
Arnold is in custody at the Hennepin County Adult Detention Facility on $750,000 bail. He has a history of convictions for drug possession and theft.
