A months-long investigation into a suspected drug trafficking operation on the east side of Saint Paul ended with the seizure of methamphetamine, cocaine, a stolen handgun and a rifle.

Ruben Castillo Renteria, 53, of Saint Paul faces three felony charges in Ramsey County: first-degree drug possession involving 50 or more grams of cocaine or methamphetamine, third-degree drug possession and receiving stolen property.

According to a criminal complaint, a Ramsey County investigator assigned to the Violent Crime Enforcement Team was told by two cooperating witnesses in November 2025 that Renteria was trafficking a large amount of methamphetamine from his residence on the 600 block of Lawson Avenue East.
