For four months, members of Berks County District Attorney John T. Adams’ drug task force eavesdropped on the cellphone conversations of a Pennside resident and others suspected of selling large quantities of cocaine, heroin and marijuana in the county.
The state Superior Court approved Adams’ application for a nonconsensual wiretap in February to listen to the conversations of Robert Sanfiel, 47.
By that time, Adams said Thursday, the detectives had been investigating Sanfiel for six months, but early on didn’t know the size of the operation.
The investigation culminated early Thursday when investigators began a roundup of 25 people accused of being involved in the organization.
