LOUISVILLE, Ky. (WDRB) -- Alcohol may have played a role in a fatal ATV crash in Orange County, Indiana 

According to a news release from Indiana Conservation officers, 55-year-old John Burbrink died at IU Health Hospital in Paoli from a severe closed head injury after crashing his ATV on County Road 750 N, outside of Orleans. 

Alcohol is suspected to have been a contributing factor, but toxicology results are pending.  

Burbrink had been riding with a group of friends when he lost control and was ejected from his Arctic Cat ATV, which subsequently landed on top of him. His fellow riders immediately began CPR, but were unsuccessful in their attempts to revive him.

Burbrink was not wearing a helmet or any safety equipment. Indiana Conservation Officers strongly encourage riders to always wear a helmet and necessary safety equipment when operating an ATV.
