State Police reported they found 300 pounds of suspected marijuana in the cargo area of a Mississippi man’s vehicle following a Sunday morning traffic stop on Interstate 12 near Hammond.

Troopers stopped an eastbound 2015 Mazda CX-5 for a traffic violation on I-12 near its intersection with Interstate 55 about 9 a.m., and after speaking with driver Carlos Davis, 26, of Greenwood, Mississippi, officers soon became suspicious, Sgt. Nick Manale said Monday.

Davis refused consent to a vehicle search, so troopers called in a Tangipahoa Parish Sheriff’s Office police dog. The dog alerted to the car, and the troopers’ search uncovered the marijuana, with an estimated street value of $250,000, in the back seat and rear cargo area of the vehicle, Manale said.

State Police worked with the Mississippi Bureau of Narcotics to conduct a controlled delivery of the marijuana at a residence in Jackson, Mississippi, leading to additional arrests, Manale said.

Davis was booked into the Tangipahoa Parish Jail on a count of possession of marijuana with intent to distribute.
