NASSAU COUNTY, FLORIDA, Fla. — An alleged member of a South Florida drug trafficking organization known as ‘The Miami Boys’ was arrested in Nassau County on a warrant out of Duval County Sunday, the Nassau County Sheriff’s Office said in a post on its Facebook page Tuesday.

Nathaniel James was arrested during a traffic stop on U.S. 1 in Callahan on Sunday, according to NCSO. Police said his arrest stems from an investigation started by the Drug Enforcement Administration (DEA) in October 2023.

In October 2023, NCSO’s post states that investigators received intelligence indicating James was delivering cocaine and fentanyl to Jacksonville.

“The investigation established probable cause that James was involved in trafficking fentanyl (28 grams or more) and cocaine (200 grams or more),” the post further states. “According to authorities, the investigation began after James allegedly sold narcotics to a confidential source in Duval County. A subsequent controlled purchase tested positive for fentanyl.”

The sheriff’s office said James has an “extensive criminal history,” including a 1991 arrest for conspiracy to possess with intent to distribute crack cocaine. He received a life sentence in December 1991, but it was later reduced to 408 months in May 2019, with 60 months of supervised release, according to police.

Nassau County Sheriff Bill Leeper said in the Facebook post that James’ arrest represents a “significant blow to drug trafficking operations” in Northeast Florida. James is currently in custody on a $1 million bond.

According to NCSO, The Miami Boys first emerged in the 1980s, operating throughout Florida and Georgia, and allegedly played a “significant role in illicit drug distribution.”
