BONNE TERRE — Missouri investigators say they've linked a man who killed himself after shooting three people to death in eastern Missouri to the gun death of another victim.
The Missouri State Highway Patrol says unspecified DNA evidence and telephone records link gunman Nathan Fortner to the shooting death of 20-year-old Erica Wade.
Wade was an acquaintance of Fortner. Her body was found in an abandoned house after authorities say Fortner went on a rampage Nov. 30, killing his ex-girlfriend, her mother and that woman's live-in boyfriend. Fortner then killed himself as police closed in.
The patrol says there's no evidence anyone other than Fortner was involved in the deaths.
Fortner's sister has said Nathan Fortner was unemployed, bipolar and overcome with despair over the breakup with his ex-girlfriend.
