EDINBURG, Texas -

Nearly 13 tons of marijuana worth about $20.5 million were seized by U.S. Border Patrol agents last week, officials announced Monday.

About half of the marijuana was seized in multiple incidents at the Falfurrias Checkpoint on U.S. Highway 281 North, agents said. The 13,000 pounds in marijuana was netted throughout the week.

One of the largest non-checkpoint seizures was made near Madero on March 26 by agents assigned to the McAllen Station. Agents working near the Rio Grande said they were attempting to stop a sport utility vehicle when the driver refused to stop and sped away. 

The driver abandoned the vehicle near the river and fled to Mexico. More than 1,200 pounds of marijuana were found inside the vehicle, agents said

Another large seizure occurred in Garceno when agents attempted to stop a Ford Expedition. Agents said another vehicle pulled in front of them to block their path.

The driver of the Expedition sped off and abandoned the vehicle near the river. The Expedition contained more than 1,000 pounds of marijuana, agents said. According to authorities, the driver of the vehicle that blocked the agents’ path was arrested.

Agents said more seizures from March 24 through March 30 pushed the total amount of marijuana seized to nearly 26,000 pounds.
