Convicted drug dealer returns to jail after massive fentanyl bust in Michigan

A massive fentanyl bust landed an already convicted drug dealer back in jail.

A lethal dose of fentanyl can be as small as two milligrams, which means the 500 grams of the drug police confiscated had the capacity to kill up to 250,000 people.

The months-long investigation led police to 53-year-old Darrell Mitchell, who already has eight felony convictions on his record.

If convicted, the 53-year-old man could face 30 years in prison.

Mitchell is due back in court later this month.
