MEMPHIS, Tenn. — Four people are in custody after drugs, cash, and weapons were found in a rental vehicle during a traffic stop on Interstate 40 in Haywood County on Wednesday, according to the West Tennessee Drug Task Force.

On July 23, West Tennessee Drug Task Force agents were patrolling I-40 in Haywood County when they observed a vehicle closely following another car.

A traffic stop and search were conducted by agents. During the search, agents found two loaded firearms, 254 pounds of promethazine, also known as “Lean”, “Purple Drank,” or “Sizzurp,” over 100 opioid pills, and three pounds of marijuana in a rental car.

Agents said four people were arrested on different drug and weapon charges.

After further investigation, agents found that the promethazine had been very recently stolen from a pharmaceutical supply business in Houston, Texas.

Agents said they are working with Houston investigators and that more charges will likely be added in Haywood County and Houston, Texas, as well.

The Haywood County Sheriff’s Office assisted with the arrest.
