Fond du Lac heroin ringleader faces more than 100 years in prison

FOND DU LAC COUNTY, Wis. (WBAY) - A man accused of running a $1 million heroin conspiracy faces more than 100 years in prison after pleading guilty to six charges in Fond du Lac County.

On Oct. 9, Allen Ferguson entered guilty pleas to five counts of manufacture/delivery of heroin and one count of possession with intent to deliver heroin (more than 50 grams.)

Ferguson entered the pleas after a half-day of testimony during trial. The trial was expected to go through Friday.

Fond du Lac County District Attorney Eric Toney says Ferguson faces 111 years in prison at sentencing.

Ferguson admitted to coming to Fond du Lac to help with the sale of heroin in the city. He then took over the operation, traveling to Chicago to pick up 200-300 grams of heroin per month and bringing it back to Wisconsin.

Toney says it is estimated Ferguson's operation was responsible for dealing 7,000 grams of heroin with a street value of more than $1 million between March 2015 and February 2017.

"This trial was originally scheduled for May of this year and was being prosecuted by DDA Dennis Krueger. Dennis unexpectedly passed away the weekend before the trial was to set to begin. Dennis was instrumental in assisting law enforcement by leading this investigation and our entire community owes a debt of gratitude to Dennis for his sacrifice and his family’s loss," Toney says.

All co-defendants in the conspiracy have been convicted.
