Federal officials have charged 20 people with being part of a cocaine-crack operation that stretched from Cliffwood in Monmouth County to Brick in Ocean County.

The U.S. Attorney's Office on Thursday said the FBI used court-authorized wiretapping techniques to listen to phone calls and read text messages between the suspects.

Prosecutors say Damion Helmes, 39, of Cliffwood, got his cocaine supply from Derrick Hayes, 37, of Neptune Township, and Dequan Copeland, 40, of Red Bank. Investigators say Helmes turned a portion of the cocaine into crack and supplied it to other dealers.

Officials said the drug-dealing conspiracy took place in Cliffwood, Keansburg, Matawan, Keyport, Red Bank, Long Branch, Neptune Township, Asbury Park and Brick.

Of the 20 people charged, Keith Logan, 38, Long Branch, remained at large on Thursday.
