Big Bend Sector Border Patrol agents found the drugs in large backpacks that were in the back seat of a white pickup truck that agents pulled over south of Fort Stockton on February 7th.
An alert citizen reportedly called the Sanderson Border Patrol office shortly before the traffic stop and said a truck was being loaded with large bundles along U.S 90 west of Sanderson.
The citizen gave a description of the vehicle, and Border Patrol agents and Pecos County Sheriff's deputies quickly set up posts on nearby roads.
A U.S. Border Patrol K-9 team and a Pecos County Sheriff's deputy were watching traffic along U.S. 285 when they spotted the pickup truck and pulled it over.
Agents seized the marijuana in the pickup truck -- which weighed 226 pounds -- and they took the 3 men inside the pickup truck into custody without incident.
Agents say that the driver of the pickup truck was a 35-year-old Fort Worth man, while both passengers were illegal immigrants from Mexico.
Agents believe the immigrants crossed the Rio Grande with the marijuana-filled backpacks.
The men then allegedly walked 25 miles to U.S 90 and had the pickup truck driver pick them up.
The 3 men, the truck and the marijuana were turned over to the Drug Enforcement Administration's Alpine, Texas Field Office for further investigation.
