Edward Y. Kim, acting U.S. attorney for the Southern District of New York, and NYPD Commissioner Jessica S. Tisch announced the charges against Jarjou on Tuesday, which they said relate to Jarjou’s alleged membership in the “Rollin 20s” set of the Crips gang and the March 9, 2021 murder of Robinson.

They said Jarjou, who was in New York City Department of Correction custody, was transferred to federal custody earlier on Tuesday and made his initial appearance in federal court in Manhattan. The case has been assigned to U.S. District Judge Edgardo Ramos.

In the context of the charges, Kim said, “As alleged, Alieu Jarjou shot and killed Jadon Robinson on a busy Bronx street in the middle of the day. He committed this cold-blooded murder to enhance his status within the Rollin 20s Crips, a violent street gang that traffics in illegal drugs. Let this be a reminder that this Office and our law enforcement partners will catch and prosecute those who commit acts of violence in our streets.”

According to federal court records, from at least January 2021 through at least January 2022, Jarjou was a member of the Rollin 20s Crips, a gang based in The Bronx. In order to fund the gang, protect its territory, and promote its standing, members of the Rollin 20s Crips engaged in, among other things, murders, assaults, threats of violence, and drug trafficking. On March 9, 2021, Jarjou allegedly murdered Robinson in the vicinity of 1268 Morrison Avenue in Soundview.

Prosecutors said Jarjou, 30, also of The Bronx, is charged with one count of racketeering conspiracy, which carries a maximum sentence of life in prison; one count of murder in aid of racketeering, which carries a sentence of mandatory life in prison or death; one count of murder through the use of a firearm, which carries a maximum sentence of life in prison; and one count of using and carrying a firearm during and in relation to a crime of violence, which carries a maximum sentence of life in prison.

The maximum potential sentences in this case are prescribed by Congress and provided for informational purposes only. Any sentencing of the defendant will be determined by the judge.

Kim praised what he described as the outstanding investigative work of the NYPD. The case is being handled by the Southern District of New York’s Violent and Organized Crime Unit. Assistant U.S. Attorneys Christy Slavik and Jim Ligtenberg are leading the prosecution.

The defendant is deemed innocent unless and until proven guilty in a court of law.
