A trial date has been set for a third person charged in the heroin overdose death of a Fond du lac County man two years ago. Alonzo Cornelius of Milwaukee is charged with first degree reckless homicide-delivery of drugs and manufacture-delivery of heroin as a repeater. A trial date has been scheduled for October 5th. Cornelius is the third person charged in the heroin overdose death of town of Springvale resident Devin Perry in October of 2012. Fond du Lac resident, Jason Van Norman and Waupun resident Joshua Mulder were earlier convicted for their roles. Van Norman was sentenced earlier this month to 10 years in prison and 10 years extended supervision. Cornelius is the person investigators believe sold the heroin that eventually ended up in the hands of the victim. He is being held in the Fond du Lac County Jail on $250,000 cash bond.
