There's a break in a decades-old case, in which a Parkersburg woman was reported missing, then presumed to be dead, and in which a suspect was eventually convicted of her murder.

Parkersburg Police say human remains recently found near the Ohio River in Belpre have been positively identified as those of Leslie Diane Marty, who was last seen at the Parkersburg apartment of an acquaintance in 1983.

Mark Francis Hanna, now 60, was convicted of her kidnapping in the 1980's, then, in another trial in 1998, convicted of Marty's murder. He is serving a life prison sentence.
