In a stunning administrative decision that has jeopardized one of America’s largest criminal investigations, U.S. Immigration and Customs Enforcement (ICE) permitted the central suspect in a monumental $100 million jewelry theft to voluntarily depart for South America in December 2022. This unexpected deportation has created significant tensions between federal agencies and left prosecutors scrambling to salvage their case.
Jeson Nelon Presilla Flores, identified as a key operative in the sophisticated 2022 armored truck robbery, faced substantial federal charges including conspiracy to commit theft from interstate and foreign shipment. The meticulously planned heist targeted a Brink’s tractor-trailer transporting precious gems and luxury watches from an international jewelry show near San Francisco. While court documents indicate Flores pleaded not guilty, conviction could have resulted in a 15-year prison sentence.
The deportation occurred despite Flores’ status as a lawful permanent resident who had been released on bail. Defense attorney John D. Robertson subsequently filed a motion to permanently dismiss the indictment, arguing that ICE’s intervention violated his client’s criminal prosecution rights. Federal prosecutors have opposed this motion, requesting dismissal “without prejudice” to preserve future prosecution options should Flores reenter the United States.
Legal experts characterize this interagency breakdown as highly unusual for a case of this magnitude. Former federal prosecutor Laurie Levenson noted the extraordinary nature of the deportation, stating, “It’s just beyond me how they would deport him without the prosecutors… being in on the conversation. This really was the left hand not knowing what the right hand was doing.”
The aftermath has left numerous jewelry companies demanding answers and closure. Attorney Jerry Kroll, representing affected jewelers, emphasized the victims’ perspective: “When a defendant in a major federal theft case leaves the country before trial, victims are left without answers, without a verdict, and without closure.”
Discrepancies in the reported value of stolen merchandise continue to complicate the case, with victims claiming over $100 million in losses while Brink’s security company maintains the stolen items were valued under $10 million.
