CAMDEN — A North Carolina sheriff thinks a new lead could solve a 20-year-old murder investigation.

Camden County Sheriff Tony Perry has reopened the case of 33-year-old Polly Lynch. She was found off a road two days after being seen at a bar on New Year’s Eve 1991.

All of the people who were with her were interviewed except for a motorcycle gang member only known by a nickname.

A sheriff’s detective last week spoke with police in Chesapeake, Va., and the meeting developed the missing man’s full name, address and recent photo.

Investigators now are looking for the man to interview him about where he was when Lynch was shot twice in the head.
