HAWKESBURY, Ont. -- Provincial police are appealing for any possible tips in the death of an 18-year-old woman in eastern Ontario three years ago.

The body of Jessica Godin was found in a ditch in Fournier, in Nation Township, on Sept. 24, 2011.

Investigators believe she died as a result of a hit-and-run collision.

Police say officers have conducted almost 100 interviews and completed more than 300 assignments in an attempt to identify the suspects.

They believe that someone has information that would help them solve the crime.

Police also announced the renewal of a $100,000 reward for information leading to an arrest and conviction in the case.
