The Vigo County Sheriff’s office continues investigating 11 unsolved murders.
Some of these cases date back to 1975.
Former Sheriff Bill Harris volunteers his time to continue the investigations.
The department is currently focusing on the July 1980 murder of Gloria Hedden.
She was found bound and floating in the Wabash River just three days after she disappeared.
Police say that over time things change and people who might know something might be more willing to talk now that relationships might have changed, or someone might have passed away.
If you know something contact the Vigo County Sheriff’s Department.
