Gary Jones's impact on his students at The Westminster School was apparent as students wrote thank-you notes to volunteers assisting in the search.

LAKE OCONEE, Ga. — Cold weather is forcing investigators to alter their search for a missing boater on Lake Oconee. Channel 2′s Tyisha Fernandes learned that cadaver dogs couldn’t search for Westminster teacher and track coach Gary Jones on Wednesday because the air temperature is colder than the water.

Inclement weather derailed searches earlier this week, but on Friday search crews, including Gary Jones' family, combed the waters for signs of him.
