NASHVILLE: A four-month investigation into the distribution of opioids culminated in today's execution of search warrants at three Nashville locations and the seizure of 7 pounds of heroin, 10 grams of cocaine, 2.5 pounds of marijuana, 1 pistol and $4,025 cash. The MNPD crime laboratory will be analyzing the heroin for any fentanyl content.

Five pounds of the heroin was recovered from 1023 Pleasant View Drive. Also found was a press for bricking kilograms of heroin, cutting agents, face masks, latex gloves and plastic baggies. Arrested there for felony possession of heroin for resale was convicted drug felon Jerome L. Wilkerson, 40, who received a 10-year probated sentence in 2015 on two felony cocaine counts. Wilkerson was convicted of voluntary manslaughter in 2002 and received a 10-year sentence.

Also arrested today were convicted cocaine felons and brothers Lafonte Gregory, 31, and Belafonte Gregory, 33, after search warrants were executed at their residences. Inside Lafonte Gregory's 218 Larkin Springs Drive home, detectives found baggies containing heroin, cocaine, marijuana and a .45 caliber pistol. Lafonte Gregory received a 10-year sentence stemming from his arrest in 2010 in a felony cocaine case.

Inside Belafonte Gregory's 5428 Daniel Ray Drive residence, detectives found a baggie of heroin, drug paraphernalia and the seized cash. He received a 9-year sentence in 2007 in a felony cocaine case.

The investigation shows that heroin transactions had taken place on the property of the brothers' barbershop, Chop it Up, on S. Gallatin Pike.

Wilkerson is jailed in lieu of $80,000 bond on heroin and drug paraphernalia charges. Lafonte Gregory is jailed in lieu of $75,500 bond on heroin, cocaine, marijuana and gun charges. Belafonte Gregory was released after posting a $45,000 bond on heroin and drug paraphernalia charges.

This investigation is being conducted by the MNPD's Major Case Task Force with assistance from the DEA, FBI and TBI.
