LAKE CHARLES, La. — Shortly before 11 a.m. Thursday, a Louisiana State Police trooper working commercial motor vehicle enforcement conducted a traffic stop on Interstate 10 west of Louisiana Highway 397.

The traffic stop ultimately resulted in the discovery of a large amount of cocaine and led to the arrest of 27-year-old Oscar Jasso of Mission, Texas.

A traffic stop was initiated for a compliance check on a 2011 Peterbilt (18-wheeler) that was headed east on Interstate 10.

During the course of the commercial motor vehicle inspection and the interaction with Jasso, signs of criminal behavior were detected, authorities said.

A consent to search was denied and a K-9 was deployed. After the K-9 positively alerted, a search of the 18-wheeler was conducted.

The Trooper located 20 bundles of cocaine found within the cab of the 18-wheeler. The estimated street value of the cocaine is approximately $500,000.

Jasso was cited for several inspection violations and arrested for possession with the intent to distribute a controlled dangerous substance schedule II.

He was booked into the Calcasieu Parish Correctional Center without incident.
