A Decatur man is heading to prison after being sentenced in a December drunk driving incident that killed a Bloomington man. 

31-year old Brayone Murff pleaded guilty to aggravated DUI and is set to serve 8 years in prison.  Murff struck another vehicle but a passenger in his car, 31-year old Tony Buck, died in the crash.  McLean County law enforcement says Murff was high on marijuana during the incident. 

He must serve at least 85 percent of his 8-year term.
