Dominik Israel Lopez, a 24-year-old resident of Mesa, Arizona, has been sentenced to nine years in federal prison for distributing fentanyl that resulted in a fatal overdose. The sentencing took place on November 24, 2025, before United States District Judge Krissa Lanham. After serving his sentence, Lopez will be subject to three years of supervised release.
The case stems from an incident in March 2020 when a man was found dead in his Gilbert apartment. The Maricopa County Medical Examiner determined the cause of death was fentanyl toxicity. Investigators discovered that the victim had contacted Lopez through the messaging app Whisper and purchased four fentanyl pills for $40. The victim used one pill and died from an overdose.
United States Attorney Timothy Courchaine commented on the broader impact of such cases: “At the end of every drug overdose death are countless victims,” said Courchaine. “There are the dead, taken too early, families who lose loved ones, and communities slowly being torn apart. This sentence shows that the Department of Justice will pursue harsh penalties for all drug dealers. I am proud to stand alongside the victim’s family and our law enforcement partners in holding this defendant accountable.”
DEA Phoenix Special Agent in Charge Cheri Oz emphasized law enforcement’s ongoing efforts: “Drug traffickers who deal deadly drugs and destroy lives will face justice,” said Oz. “The DEA, alongside our dedicated partners, remains steadfast in our mission to save lives and achieve a Fentanyl-Free America.”
Gilbert Police Chief Michael Soelberg also addressed community safety: “The Gilbert Police Department works in close partnership with law enforcement agencies in the ongoing fight against illegal drugs, including holding accountable those whose actions result in death through drug distribution,” said Soelberg. “We remain steadfast in our relentless pursuit of those who victimize our community.”
Fentanyl is described as a synthetic opioid about 50 times more potent than heroin; even two milligrams can be lethal. Counterfeit pills containing fentanyl are frequently sold via social media platforms. According to data from the Centers for Disease Control and Prevention (CDC), drug overdoses and poisonings now represent the leading cause of death among Americans aged 18-45.
Authorities warn that legitimate pharmaceutical medications should only be obtained through prescriptions from licensed medical professionals and dispensed by pharmacists; purchasing pills on social media is unsafe.
The investigation was conducted by the United States Drug Enforcement Administration and the Gilbert Police Department. Assistant U.S. Attorneys Brandon Brown and Jason Crowley prosecuted the case.
