THE BRONX - Officials say three leaders of a heroin ring have pleaded guilty after a massive multi-agency investigation.

Wilson Guerrero, Franklin "Kelly" Perez and Antonio "Tony" Carrasquillo faced a judge Friday.

Authorities say the three men were leaders of the "La Perla" organization.

The arrests came after an investigation that resulted in a 38-defendant indictment on narcotics charges.

Authorities say they recovered $1.6 million in cash, 4 kilograms of heroin, guns, cars and jewelry during their probe.
