COLUMBUS (AP) — Federal and state authorities Thursday announced the sentencing of the latest member of an Ohio branch of the violent El Salvador-based MS-13 gang.

At a news conference, they said Juan Flores-Castro, 32, of Columbus, has been sentenced in U.S. District Court to 35 years in federal prison. Flores-Castro is the ninth defendant to be convicted and sentenced to at least 30 years in prison for committing murder on behalf of the transnational criminal organization.

The others include:

  • Martin Neftali Aguilar-Rivera (“Momia”) – sentenced to life in prison without parole
  • Jose Bonilla-Mejia (“Espia”) – sentenced to life in prison without parole
  • Pedro Alfonso Osorio-Flores (“Smokey”) – sentenced to 40 years in prison
  • Jose Manuel Romero-Parada (“Russo”) – sentenced to 40 years in prison
  • Jose Salvador Gonzalez-Campos (“Danger”) – sentenced to 40 years in prison
  • Juan Jose Jimenez-Montufar (“Chele Trece”) – sentenced to 35 years in prison
  • Jose Daniel Gonzalez-Campos (“Flaco”) – sentenced to 30 years in prison
  • Jose Mendez-Peraza (“Shadow”) – sentenced to 30 years in prison

The long-term MS-13 investigation included the solving of eight homicides, according to officials.

Over the years, racketeering conspiracy charges against gang members have included murder, attempted murder, assault, drug trafficking, and money laundering.

Authorities said one more suspect, Daniel Alexander Diaz-Romero (“Manchas”), remains at large.

Across the country, federal authorities have brought multiple charges against MS-13 members in recent years.

On Wednesday, the acting U.S. Attorney in Nashville announced that nine MS-13 members face charges alleging their involvement in killings, kidnappings, assaults, robberies and large-scale drug distribution in and around Nashville.

On July 20, an MS-13 member in Maryland was sentenced to 30 years in federal prison for his role in the killing of a 16-year-old boy who was stabbed and cut more than 100 times before his body was set on fire.

Authorities have also prosecuted MS-13 members for a series of killings on Long Island.
