Two Miami residents have pleaded guilty to conspiring to export nearly 600 stolen outboards to Mexico through a Miami-based freight company.

Carlos Orlando Ledesma, 57, and Nadia Esperanza Ledesma, 46, join co-defendants Roberto Marrero-Cisneros, 65, and Osmani Valdivia Perez, 55, who also pleaded guilty to the conspiracy charge.

In a statement, the U.S. Attorney’s Office, Southern District of Florida, said Nadia Ledesma is president of Netcycle Trading Corp., a freight-forwarding company, and Carlos Ledesma is the warehouse manager. According to court documents, they received from 2015 to 2018 almost 600 stolen outboards for export to Mexico.

“Dozens of individuals delivered the stolen engines,” the statement said. “The engines had visible damage from the thefts, and cables and lines had been cut rather than properly detached.”

The engines were reportedly delivered in non-commercial vehicles without bills of sale or other documentation.

According to court documents, Marrero-Cisneros created false serial numbers for the stolen engines. False bills of sale and exportation documents were also created.

Prosecutors say payments to co-conspirators covered fees to export the stolen outboards, payments to Marrero-Cisneros for the false serial numbers, and payments to the individuals who allegedly stole the engines.

U.S. District Judge Robert N. Scola Jr. set sentencing hearings for Marrero-Cisneros and Valdivia Perez on May 8, and for Carlos and Nadia Ledesma on May 23.
