Durham offers reward for help with unsolved homicide

The litter crew was working about a mile north of Snow Hill Road on June 30, 2010, when they spotted a large plastic bag and found human remains inside, authorities said.

Wanda Rose Spence, 43, of Elmo Street, was last seen alive a week earlier in the area of Juniper Street and North Hyde Park Avenue, authorities said. They used dental records to identify her body.

The sheriff's office never released a cause of death for Spence, but they have been treating her death as a homicide.
