Matthew Grant goes missing from RIT, search begins

Grant, a Henrietta resident, went missing on Monday, Nov. 20. He was driving a 2014 charcoal gray Jeep Cherokee with a Michigan license plate. During the search, the E-ZPass in the Jeep was recorded on the New York State Thruway at Exit 36 (Interstate 81) near Syracuse. The search for Grant was subsequently expanded to the Adirondacks region.

Earlier in December, police announced the discovery of surveillance footage showing Grant at a gas station located between Exit 41 (Waterloo) and Exit 39 (Syracuse) just before midnight on Nov. 20. In the footage, Grant appeared to be alone and not in distress inside the convenience store of the gas station.

Grant, who is from Onaway, Michigan, is majoring in mechanical engineering and is a captain on the Tigers' wrestling team, according to RIT athletics.
