Three people were arrested over the weekend after investigators found around 36,000 pills of a potentially deadly narcotic under the hood of the vehicle they were in, the Caldwell County Sheriff’s Office said.

Jermaine Doglas Grandy, 39, and Nevaeh Douglas Grandy, 18, both of Old North Road in the Lenoir area, and Khyran Rasaan Littlejohn, 25, of Patton Place in Morganton were a “major pipeline” for fentanyl pills in Caldwell County and the surrounding region, Sheriff Alan Jones said in a press release.

The three were the object for a multi-agency investigation that started at least several months ago and involved the Caldwell County Sheriff’s Office, the Alexander County Sheriff’s Office, the N.C. State Bureau of Investigation, the Boone Police Department, the Taylorsville Police Department, the Lenoir Police Department, and the Catawba County Sheriff’s Office.

The group was arrested Sunday after investigators stopped the 2018 Mercedes-Benz they were in on U.S. 321 Granite Falls.

In a search of the vehicle, investigators found over 9 pounds of pills, $894 cash and three handguns, the press release said.

The drugs seized have a street value of $1.08 million according to North Carolina State Drug Guidelines.

Investigators also searched the Grandys’ home on Old North Road and found 29 guns and more than 5,000 rounds of ammunition.

Jemaine Grandy was charged with trafficking heroin or opium. His bond was set at $500,000 secured.

Nevaeh Grandy and Khyran Littlejon were charged with two counts each of trafficking heroin or opium. Their bonds were each set at $100,000 secured.
