(Multnomah County, OR)  --  A Portland man is a suspect in a fifth cold case murder.  A superseding indictment filed Friday accuses Homer Lee Jackson of the 1993 death of 29-year-old Lawauna Triplet.  The 59-year-old man was indicted in 2015 for the intentional killings of four other women.  Charges were dropped in one of those cases, but Jackson is still a suspect in that death.
