A Mexican national who authorities say had been deported five times from the U.S. was arrested in Fort Lauderdale on a charge of trafficking about 50,000 fentanyl pills hidden inside a Sesame Street-style school bus toy.

Guillermo Higuera German, 37, was ordered detained on Friday by a federal magistrate judge after his Nov. 15 arrest in a Walgreens parking lot on Broward Boulevard by Fort Lauderdale Police and Drug Enforcement Administration agents. His arraignment on a charge of possession with intent to distribute a controlled substance will be held in December in Fort Lauderdale federal court.

According to a DEA affidavit, police officers responded to an incident that occurred at the Walgreens in the 700 block of West Broward Boulevard. Officers said they saw a “suspicious” vehicle parked in the lot. They approached the vehicle, which was driven by Higuera German, who said he did not have a valid U.S. driver’s license and provided auto insurance for another person.

During a consensual encounter in the Walgreens parking lot, a certified narcotics K-9 conducted an open-air sniff and detected narcotics in the vehicle, the affidavit says.

Officers found several boxes and the Sesame Street-style school bus toy packed with thousands of fentanyl pills that weighed about five kilograms, or 11 pounds, the affidavit says. They called in DEA agents for assistance.

DEA agents did a field test of one of the pills, which tested positive for fentanyl. It’s a highly dangerous synthetic heroin that along with other opioids accounts for the majority of about 100,000 overdose deaths a year in the United States.

After he was read his Miranda rights, Higuera German confessed to DEA agents that “he was going to deliver the packages and be paid between $30,000 to $100,000 … for the bundles,” according to the affidavit filed with a criminal complaint for his arrest.

“Higuera German also stated that he was aware that he was transporting narcotics,” the affidavit says.

In addition to the criminal case, Higuera German, a Mexican citizen with no legal status in the U.S., is again subject to removal. The Federal Public Defender’s Office is representing him.

The investigation determined that Higuera German was illegally in the U.S. and had been deported five times, according to U.S. Customs and Border Protection.

The case is being prosecuted by the newly formed Border and Immigration Crimes Enforcement Section (BICE) of the U.S. Attorney’s Office in South Florida. BICE was created by U.S. Attorney Jason Reding Quiñones as part of the Trump administration’s agenda to target illegal immigration, drug trafficking and violent crime.
