Joel Casas-Santiago has pleaded guilty to one count of conspiracy to distribute methamphetamine after authorities seized nearly 900 pounds of meth from two vehicles in St. Paul, Minnesota last July. His co-defendant, Guillermo Mercado-Chaparro, previously pleaded guilty to the same charge.

Why it matters

This case represents one of the largest drug busts in Minnesota history, highlighting the scale of the methamphetamine crisis in the state and the ongoing efforts by law enforcement to disrupt major drug trafficking operations.

The details

According to court documents, an undercover police officer purchased a pound of meth from Mercado-Chaparro, leading to surveillance that observed him receiving two large bags from his truck and placing them in a nearby Jeep. Police then stopped the Jeep, which was carrying Casas-Santiago and Mercado-Chaparro, and found over 250 pounds of meth. A search of Mercado-Chaparro's truck uncovered an additional 630 pounds of meth in the bed.

  • In July 2026, Casas-Santiago and Mercado-Chaparro were arrested and charged.
  • Last month, Mercado-Chaparro pleaded guilty to one count of conspiracy to distribute methamphetamine.
  • Casas-Santiago has now pleaded guilty to the same charge.
