WEEK IN REVIEW: Monroe Prosecutors Announce Series Of Sentencings Across Keys Involving Drugs, Violence, DUI Cases
Defendants receive prison terms, probation and fines in cases spanning Key West to Key Largo.
Prosecutors in Monroe County this week announced a series of convictions and sentencings across the Florida Keys, with cases ranging from narcotics trafficking and violent assaults to probation violations and DUI-related offenses.
In one of the cases, Bobby Eugene Mosby, 55, of Key West, was sentenced to 24 months in state prison followed by 24 months of probation after pleading no contest in two felony drug cases before Circuit Judge Mark Jones. Authorities said the convictions included sale of cocaine, possession with intent to sell, and use of a communication device to facilitate drug transactions.
The charges stemmed from two Monroe County Sheriff’s Office investigations in May 2025. In one, Mosby sold about 7.5 grams of cocaine to a confidential informant during a controlled buy at a Stock Island gas station. Days later, deputies stopped him in Big Pine Key, where a K-9 alert led to the discovery of cocaine, crack cocaine and amphetamines hidden in a magnetic container beneath his vehicle. Investigators said the quantity and packaging indicated distribution, not personal use.
Mosby was also sentenced to concurrent county jail terms on related misdemeanor charges, ordered to pay $1,176 in fines and had his driver’s license revoked for six months. Assistant State Attorney Michael Tetelman prosecuted the case.
In a separate case, Joseph Ignacio Silva, 29, was sentenced to eight years in state prison after pleading no contest to two counts of aggravated assault with a deadly weapon. Judge Mark Jones imposed consecutive terms of five years and three years.
Prosecutors said Silva attacked an off-duty Key West police officer with a knife during a domestic disturbance on Feb. 1, 2025, on Ellsberg Court. The unarmed officer retreated as Silva swung the knife and made threats before barricading himself inside a residence. He later surrendered without further incident. Assistant State Attorney Jon Byrne prosecuted the case.
Elsewhere, Jeffery Dyound Glenn, 54, was sentenced to 270 days in the Monroe County Jail after pleading guilty to failing to comply with sex offender registration requirements. Judge Mark Wilson also ordered Glenn to pay fines and transportation costs after authorities determined he provided an inaccurate Key West address and failed to update his driver’s license information. He had been located and arrested in Hillsborough County before being returned to Monroe County.
In the Upper Keys, Robert Joseph Perreault of Key Largo was sentenced to 42 months in state prison after violating probation tied to a prior felony battery conviction. Circuit Judge James Morgan revoked his probation following a new January 2026 battery case and additional violations, including failure to report and unpaid financial obligations. Prosecutors cited a history of violent offenses and repeated noncompliance.
Also in Plantation Key, Maxwell Daniel Burgan, 19 at the time, was adjudicated guilty and sentenced to 36 months of probation with 60 days in jail after pleading no contest to DUI with property damage and fleeing law enforcement. Authorities said Burgan led deputies on a high-speed chase along U.S. 1 in June 2024, reaching speeds over 80 mph and striking multiple vehicles before crashing. Breath tests showed alcohol levels above the legal limit. As part of his sentence, Burgan must complete DUI school, perform community service and undergo substance abuse treatment.
In another probation violation case, Carolyn Rebecca Hamm, 39, of Plantation Key, was sentenced to 17.1 months in state prison after Judge Morgan found she violated terms of probation related to a prior DUI and hit-and-run case. The violation stemmed from a January 2026 arrest in Polk County involving domestic violence battery and alcohol use.
Chief Assistant State Attorney Joseph Mansfield said the cases reflect a range of public safety concerns, from drug trafficking to repeat violent offenders and impaired driving.
“Whether it’s narcotics distribution, violence, or repeated violations of probation, these cases show a pattern of conduct that puts the public at risk,” Mansfield said. “Our office will continue to work with law enforcement to ensure accountability and protect the community.”
All defendants are considered innocent until proven guilty in a court of law.
