Thirty-nine people are facing felony and misdemeanor charges after Polk County investigators say they dismantled a fentanyl and methamphetamine trafficking organization allegedly run by a Lakeland man who had been out of state prison for barely a year. Detectives seized 4.4 pounds of fentanyl, 2.2 pounds of methamphetamine, 1.5 pounds of cocaine, 7.8 pounds of marijuana, two firearms and roughly $4,650 in cash during the investigation, dubbed Operation End of Worlds.
The Polk County Sheriff's Office says the probe was a joint effort involving its own HIDTA Task Force, the Florida Department of Law Enforcement and the Auburndale Police Department. According to a Polk County Sheriff release, detectives executed four search warrants and used wiretaps and surveillance to trace the network from street-level couriers up to its alleged ringleader, identified as 44-year-old Michael Edwin Worlds Jr.

Investigators say Worlds had been released from state prison in May 2025 after serving eight separate prison terms and accumulating 14 prior felony convictions and 14 misdemeanor convictions. He lived at 1521 East Memorial Boulevard in Lakeland and was found in possession of $3,250 in cash at the time of his arrest, according to the sheriff's office. Worlds now faces 67 total felonies and, per the release, a 25-year mandatory minimum sentence in state prison. Court records reviewed by Justia Law show Worlds previously appealed a Polk County conviction to Florida's Sixth District Court of Appeal, which affirmed the trial court's judgment in February 2024.
Tracing the Supply Chain From Lakeland to Auburndale
Detectives allege Worlds supplied drugs to Demairo Harden, a Lakeland man they had been investigating since earlier this year on suspicion of supplying fentanyl locally. Harden is now charged with multiple fentanyl-trafficking offenses and conspiracy to traffic methamphetamine, facing the same 25-year mandatory minimum, the sheriff's office says. Justia Law records indicate Harden had previously appealed a separate Polk County case to Florida's Second District Court of Appeal in November 2022.
Investigators identified Nickolas Brantley as Worlds' supplier, charging him with trafficking cocaine and conspiracy to traffic fentanyl after he was found with 230.85 grams of cocaine and 4.23 grams of marijuana, along with ammunition he allegedly possessed as a convicted felon, per the sheriff's release. Cherrish Willis was named as Worlds' primary drug courier and was charged with armed trafficking in fentanyl and cocaine and related drug offenses. Deputies say Willis was carrying 146.77 grams of cocaine, 203.63 grams of marijuana, 334.96 grams of fentanyl, 1.06 grams of methamphetamine, and a Glock 19 handgun that had been reported missing from within Tampa Police Department jurisdiction — a detail investigators have not further explained.
Additional Traffickers and a Fentanyl Courier
Garius Johnson was identified as a fentanyl courier and charged with trafficking fentanyl and related drug offenses after being found with 21.33 grams of marijuana. Melissa Jessica Sanchez, charged with trafficking fentanyl and cocaine and related offenses, was allegedly found with 380.62 grams of cocaine, 773 grams of fentanyl, and 3,580.04 grams of marijuana — among the largest single hauls described in the release. William Francis Massey, James Campbell, and Donovan Demond Holmes were each charged with trafficking methamphetamine over 200 grams, a threshold that under Florida Statute 893.135 carries a 15-year mandatory minimum prison sentence and a $250,000 fine, according to the Florida Legislature.
Other defendants named in the sheriff's release include Shane Ryan Chewning, charged with multiple fentanyl-trafficking offenses and conspiracy charges and facing a 25-year mandatory minimum; Kristy Chewning, charged with multiple fentanyl-trafficking offenses; Cynthia Green, charged with trafficking fentanyl and conspiracy offenses; Attrice Brooks, charged with fentanyl and methamphetamine trafficking offenses; Valyncia Burch, charged with trafficking methamphetamine and related offenses after allegedly being found with 58.2 grams of methamphetamine and $1,400 in cash; and Kidanny Rivera Rolon, charged with armed trafficking in fentanyl and possession of a firearm by a convicted felon.
In total, the sheriff's office says 18 suspects were charged with drug trafficking and face 25-year minimum-mandatory sentences. Undercover drug purchases led to 31 additional arrests, including 18 felony-trafficking arrests, while other enforcement action swept up unrelated cases — Marc Kidwell was arrested for driving with a suspended license, and Karen Bowman was arrested for resisting arrest. Altogether, the operation produced 249 felony charges and 42 misdemeanor charges. The 39 suspects collectively carried 176 prior felonies, 49 prior felony convictions, 79 misdemeanor convictions and 177 previous misdemeanors, per the release, and all trafficking suspects are being held without bond.
Mandatory Sentences and a Statewide Funding Push
Florida law leaves little room for judicial discretion once trafficking weight thresholds are met. Under Florida Statute 893.135, possessing or trafficking 28 grams or more of fentanyl triggers a mandatory 25-year minimum prison term and a $500,000 fine, a penalty structure the state expanded in October 2023 to also impose a 7-year mandatory minimum starting at just 4 grams, according to the Online Sunshine statute database. Prosecutors could theoretically pursue even harsher charges: under Florida Statute 782.04, adults who sell or deliver fentanyl that causes a fatal overdose can be charged with first-degree murder, a tool Polk County has used before, including in a Dundee man's murder indictment following a Winter Haven hotel fentanyl deal detailed in earlier Hoodline reporting.
The investigation drew resources from Florida's State Assistance for Fentanyl Eradication grant program, created by the Legislature in 2023 to reimburse local agencies for overtime, equipment and operational costs tied to multi-agency fentanyl investigations, according to the Florida Department of Law Enforcement. The Florida Attorney General's Office reported in May 2025 that the S.A.F.E. grant program had produced more than 1,500 arrests statewide and the seizure of over 170 kilograms of fentanyl and 57,000 fentanyl pills in its first year.
Sheriff Grady Judd said investigators infiltrated dealers to identify suppliers further up the chain, crediting the approach with saving lives, while Mark Dubina said collaboration among agencies allows drug trafficking organizations to be dismantled efficiently and durably, per the sheriff's office statement. Operation End of Worlds follows an August sting detailed in a prior Hoodline report that targeted fentanyl and MDMA distribution in Winter Haven, and it echoes a 2023 case in which Polk County deputies and the FDLE seized 10 kilograms of fentanyl tied to Mexico's Sinaloa Cartel, at the time the largest fentanyl bust in county history, according to the sheriff's office.
State health data offers some context for the stepped-up enforcement. The Florida Department of Health recorded 7,220 drug overdose deaths in 2023, with Central Florida counties including Polk seeing persistent surges in illicit methamphetamine and fentanyl supply, per a report from Design Recovery. More recently, state data released in May showed fentanyl-caused deaths across Florida dropped 46% in the first half of 2025 compared to prior years, with overall drug-related fatalities falling 19% over the same period, according to FOX 13 Tampa Bay. It remains unclear where the network's top suppliers, including Brantley, originally sourced their bulk narcotics, and investigators have not said how the missing Tampa Police Department Glock 19 ended up in Willis's possession.
