A Massachusetts man is facing several drug charges after thousands of fentanyl pills and about 30 pounds of cocaine were seized from his home last month, Hampden County District Attorney Anthony Gulluni announced on Wednesday.

Alonzo Williams, 51, was charged with trafficking in fentanyl over 200 grams, trafficking in cocaine over 200 grams, possession of a firearm without a license, and other counts related to distributing drugs.

His arrest came after a lengthy investigation into alleged drug trafficking at his home in Springfield, Massachusetts.

A search of his home allegedly turned up a stockpile of drugs with a street value of $2 million, including about 13,900 fentanyl pills, 406 grams of raw fentanyl, and roughly 30 pounds of cocaine. Detectives also seized $190,000 in counterfeit cash.

"We have begun educating the public on the dangers of pills containing fentanyl and how they are causing a rash of overdoses across the Commonwealth," the district attorney said in a statement.

"With this interception of almost 14,000 of these pills, countless overdoses were surely prevented."
