Simpsonville Drug Dealer Found Guilty of Fentanyl Overdose that Killed Greenville Man

GREENVILLE, S.C. —A federal jury has convicted Mylique McFadden, 28, of Simpsonville, of distribution of fentanyl resulting in death and two counts of possession with the intent to distribute marijuana. The guilty verdict was returned after three days of trial.

“This defendant showed no regard for life by continuing to distribute drugs even after this victim died of an overdose,” said U.S. Attorney Bryan Stirling for the District of South Carolina. “Fentanyl poses a dangerous health risk in our communities, and we’ll continue to prosecute those who distribute it in South Carolina. We send our continued sympathies to the loved ones of the young man who lost his life.”

“This conviction sends a powerful message: those who distribute deadly drugs that devastate families, like fentanyl, will face justice,” said Homeland Security Investigations Charlotte Special Agent in Charge Cardell T. Morant, who also oversees North and South Carolina. “McFadden’s blatant disregard for human life, even after learning of the victim’s death, underscores the dangers posed by drug traffickers. HSI and our law enforcement partners remain unwavering in our commitment to protecting communities and holding those who spread this poison accountable.”

According to evidence presented during trial, McFadden distributed fentanyl to a 28-year-old Greenville man at a Simpsonville gas station.  Forty-five minutes later the victim was found unresponsive by a loved one.  First responders administered Narcan and conducted CPR but were not able to revive the victim. 

Law enforcement recovered the victim’s phone and discovered the text messages between the victim and McFadden arranging the drug deal. They also obtained video surveillance from the gas station that showed the meeting. 

Officers obtained a search and seizure warrant for McFadden’s electronic devices.  A review of the phones showed multiple messages wherein McFadden was arranging for the sale of marijuana, methamphetamine, and other hard drugs. Evidence showed that McFadden learned about the victim’s death on same evening it occurred. He immediately obtained a new phone number, reported his device as missing, and performed several incriminating internet searches such as “what the charge if somebody die from overdose in South Carolina.”

When McFadden was arrested on January 1, 2025, on a federal warrant, he had eight packages of marijuana in his vehicle.  He was released on bond and reoffended in June 2025.  Less than two months before his federal trial, officers observed McFadden sell marijuana at another local gas station. Based on the sale and surveillance of his apartment, officers obtained and executed a search warrant on the residence.  They found over a pound of marijuana, digital scales, packaging materials, and large quantities of cash were recovered.

McFadden faces a mandatory minimum penalty of 20 years imprisonment for the fentanyl and an additional five years for the marijuana. He also faces a fine of up to $250,000, restitution, and three years of supervision to follow the term of imprisonment.  United States District Judge Jacquelyn Austin presided over the trial and will sentence McFadden after receiving and reviewing a sentencing report prepared by the U.S. Probation Office.

This case was investigated by Homeland Security Investigations, the Greenville City Police Department, and the Greenville County Sheriff’s Office as part of the Greenville County Drug Enforcement Unit. Assistant U.S. Attorney Bill Watkins and Winston Marosek are prosecuting the case.
