A Green Bay man faces life in prison after being convicted of conspiracy to distribute heroin, fentanyl, meth and cocaine, and conduct which resulted in death. A federal jury convicted 37-year-old David Shanks on a half dozen drug-related charges. Shanks was the leader of drug ring involved in the daily sale of heroin laced with fentanyl and methamphetamine between August and October of last year. Prosecutors say his drugs led to the overdose death of one person on September 10th, 2017 and two non-fatal overdoses two weeks later. Shanks will receive a mandatory life sentence due to this trial and two prior felony drug convictions.
