COLLINWOOD -- State and federal officials announced criminal charges against 32 people Wednesday for their alleged roles in a heroin trafficking ring on the Northeast side of Cleveland.

Authorities held a press conference.Some of those indicted and still at large are reportedly connected with the Lakeshore Boyz street gang.

Three people face federal charges. They are 20-year-old Derek Warner, of Cleveland, 29-year-old Willie James and Label Dunning of Cleveland and 28-year-old Nassor M. Williams, of East Cleveland.

The three are charged with multiple counts of distributing heroin.

Warner and Dunning are also charged as being felons illegally possessing firearms.

29 other defendants face state charges.

The alleged heroin sales took place between February and August of this year -- many of which authorities say took place within 1,000 feet of a school, an additional violation that makes the charge more serious.

Euclid Mayor Bill Cervenik says, "We heard the calls from our residents who asked us to get rid of the drug dealers," Euclid Mayor Bill Cervenik says. "Today I'm happy to say they won't be on our streets, instead they'll be spending time in our jails."

The announcement is the result of a year-long investigation by the Northern Ohio Law Enforcement Task Force.

County Prosecutor Tim McGinty and U.S. Attorney Steve Dettelbach announced details of the investigation.
