HAMILTON COUNTY, Ind. – Alcohol is believed to be a factor in a Morse Reservoir crash that seriously injured a 19-year-old man.

According to Indian Department of Natural Resources (DNR), first responders were called to the reservoir just before 9 p.m. Tuesday.

They found Gregory Thomas, 19, suffering from severe head and facial injuries.

Thomas was taken to Riverview Hospital before being flown to St. Vincent Indianapolis Hospital.

The other operator involved in the crash, Aiden Hobbs, 18, was not hurt, according to DNR.

Conservation officers said Thomas and Hobbs were operating separate watercraft and were attempting to jump the wake of another boat when Hobbs went airborne and landed on Thomas.

Investigators believe alcohol was a factor in the accident.

DNR is reminding the public that it is illegal to jump the wake of another boat because of unforeseen dangers.
