UNDATED (WSAU) A Randolph man has been found guilty of killing a young mother over 30 years ago. A jury picked in Jefferson County deliberated two-and-a-half hours yesterday before convicting 53-year-old Curtis Forbes of first-degree murder in the death of 18-year-old Marilyn McIntyre.

She was beaten, stabbed, and strangled in March of 1980 at her apartment in Columbus. Her husband Lane was at work at the time, and their three-month-old son was in his crib.

Forbes was a friend of the couple, dating back to their high school years. Authorities exhumed the victim’s body in 2008 to look for new evidence. And they arrested Forbes in March of ’09, saying that blood from both the killer and the victim were found in a sink at the apartment.

Columbia County Circuit Judge Alan White later decided that the D-N-A evidence could be not presented at Forbes’ seven-day trial. The defendant did not testify. He faces life in prison when he’s sentenced in January.
