A woman was arrested for an overdose death in Tampa after an investigation found the victim’s death was due to fentanyl toxicity.
Hillsborough County Sheriff’s Office detectives arrested and charged her with Murder in the First Degree Which Resulted From the Unlawful Distribution of a Controlled Substance last month, but the fentanyl investigation had been ongoing.
On December 30, 2025, deputies responded to a death investigation at a residence in the 9000 block of Hickory Circle in Tampa. Because the death appeared to be consistent with a drug overdose, the Hillsborough County Sheriff’s Office’s Opioid Overdose Investigations Section assumed the investigation.
Detectives determined the victim, 22-year-old Olivia Williams, had met with and obtained what was believed to be oxycodone pills from 25-year-old Haley Williams. Despite sharing the same last name, the two are not related, according to law enforcement.
On December 31, 2025, detectives located Williams and conducted a narcotics operation. During the operation, Williams was found to be in possession of additional adulterated pressed fentanyl pills and was arrested. A search warrant at her residence led to the seizure of approximately 60 grams of pressed fentanyl pills, a firearm, and drug paraphernalia.
According to HCSO, Williams was initially arrested and charged with: Possession of a Controlled Substance, Delivery of a Controlled Substance, and Trafficking in Fentanyl (28 Grams or More).
As the investigation continued, it was determined that the victim’s death was due to fentanyl toxicity. Toxicology results revealed the concentration of fentanyl in the victim’s system was approximately 14 times higher than a lethal dose.
According to local law enforcement, additional forensic testing confirmed the pills sold by Williams contained no oxycodone and were, in fact, pressed fentanyl pills.
An arrest warrant was obtained for Williams last month, and that’s when detectives arrested and charged her with Murder in the First Degree Which Resulted From the Unlawful Distribution of a Controlled Substance.
“Fentanyl disguised as legitimate prescription medication is one of the deadliest threats facing our community,” said Hillsborough County Sheriff Chad Chronister. “Whether it’s sold as counterfeit pills or in its pure form, fentanyl continues to steal lives. These two investigations demonstrate our unwavering commitment to identifying those responsible, building strong cases, and ensuring drug dealers whose actions result in death are held fully accountable.”
