A man from Centralia is waiting on a September 18th preliminary hearing, in regard to 3 felony charges. Those charges are in regard to the death of a former Mt. Vernon school teacher, who died while driving a jet-ski over the Labor Day weekend. 36-year-old Robert Hanselman is in jail on $500,000 bond, after being charged with 2 Class 2 felonies for operating a watercraft under the influence of alcohol, resulting in a death, and a Class 4 felony for aggravated reckless operation of a watercraft. The Illinois Department of Natural Resources is investigating the incident, which resulted in the death of 73-year-old Gary Graham, of Benton, while he was a passenger on a jet-ski that wrecked on Sunday, September 1st. Initial reports say that the 2 men were riding together on the jet-ski, while on Lake Benton, when Hanselman, who was the driver, allegedly made a quick u-turn, causing both men to be ejected into the water. Hanselman says that he swam to the still running vehicle, while Graham attempted to swim towards the dock, but ended up going under and never reached the surface. Neither men were wearing a life vest at the time.
