After months of investigation into a suspected overdose death in Riverview, Hillsborough County deputies have arrested 46-year-old Aaron Lee Morris and charged him with first-degree murder in connection with what officials say was a fatal fentanyl dose. The victim, 43-year-old Grace Remington, was found dead at a home on Balm Boyette Road in Riverview on December 29, 2025, and toxicology later showed a fatal amount of fentanyl in her system. Deputies allege Morris delivered the fentanyl prior to Remington’s death.
In a post on X by the Hillsborough County Sheriff's Office, officials said deputies had responded to a “person down” call at the Balm Boyette Road home before identifying Morris as a suspect. The agency said the arrest, carried out on June 23, 2026, followed an investigation that included toxicology testing and ultimately led detectives to name Morris as the person who delivered the drugs. Sheriff Chad Chronister wrote that “fentanyl continues to destroy lives and devastate families in our community.”

Investigation and Charges
According to HCSO, detectives worked the case for months before arresting Morris on June 23 and charging him with first-degree murder resulting from the unlawful distribution of a controlled substance. The sheriff’s office says toxicology confirmed a lethal dose of fentanyl in Remington’s system. As of the agency’s post, no further details had been released about where Morris was arrested or whether investigators are looking at any possible co-conspirators.
Fentanyl Toll and Enforcement
The case lands in the middle of a stubborn fentanyl problem in the Tampa Bay area. Axios Tampa Bay reported that fentanyl was tied to hundreds of deaths in Hillsborough County in 2023. In recent years, local and federal prosecutors have increasingly pursued murder counts and heavy federal drug charges when fatal overdoses are traced back to alleged dealers. For example, the City of Tampa announced a first-degree murder filing in a 2024 overdose case, and the U.S. Attorney’s Office has secured multi-year federal sentences in other fentanyl distribution prosecutions.
What Happens Next
Morris faces prosecution in Hillsborough County, and the investigation remains active, according to the sheriff’s office. Prosecutors have won convictions and long sentences in comparable cases elsewhere in Florida, including a Flagler County conviction that resulted in life without parole, underscoring how seriously authorities are treating overdose-related homicides. Anyone with information is asked to contact the Hillsborough County Sheriff’s Office.
