LA Man Gets Life Sentence in Fatal Fentanyl Case

Alfonso Guerrero was sentenced to life after selling fentanyl that killed a Florida man and continuing drug trafficking days later.

A Los Angeles man has been sentenced to life in federal prison after a jury found him responsible for selling fentanyl that caused the death of a Florida man, before continuing to traffic the drug just two days later.

Alfonso Guerrero, 39, received the sentence from U.S. District Judge Aileen M. Cannon after a federal jury convicted him in May 2026 on charges of conspiracy to possess with intent to distribute fentanyl resulting in death and distribution of fentanyl resulting in death.

According to court records and evidence presented during the trial, Guerrero sold fentanyl in Indian River County, Florida, on May 16, 2023. Investigators said he exchanged approximately 0.1 grams of fentanyl, commonly known as “a point,” for another controlled substance referred to as molly.

The transaction was recorded by a doorbell camera. Hours later, David Eller was found dead inside his home in Vero Beach, Florida. Investigators recovered drug paraphernalia at the scene, including a small piece of burnt aluminum foil that prosecutors said was used when Eller received the fentanyl from Guerrero on the victim’s front porch.

Prosecutors said the amount involved was extremely small but potentially deadly. A tenth of a gram of fentanyl, roughly the size of a small pinch of salt was enough to kill Eller, according to U.S. Attorney Jason A. Reding Quiñones for the Southern District of Florida.

Despite the fatal outcome of the sale, authorities said Guerrero continued his drug activity. On May 18, 2023, only two days after the transaction involving Eller, Guerrero was arrested and found in possession of additional fentanyl that investigators said was intended for distribution.

During sentencing, prosecutors also highlighted Guerrero’s criminal history, which included documented gang membership and previous convictions for attempted robbery with a firearm in California, aggravated assault in Georgia, and drug possession offenses involving cocaine and fentanyl in Florida.

“This was not a small drug deal. It was a deadly one,” Reding Quiñones said, adding that federal authorities would continue working with local law enforcement partners to trace fatal fentanyl doses back to the people responsible for distributing them.

The sentencing announcement was made by Reding Quiñones, DEA Miami Field Division Special Agent in Charge Miles Aley, and Indian River County Sheriff Eric Flowers.

The case was investigated by the Drug Enforcement Administration (DEA) Miami Field Division and the Indian River County Sheriff’s Office (IRCSO). Officials said the investigation highlights the cooperation between federal and local agencies in identifying individuals connected to fatal fentanyl overdoses and holding them accountable through the courts.
