Prosper police say a January fentanyl death inside a neighborhood home has now led to murder charges for two North Texas residents, after detectives traced what they allege was a lethal dose of the powerful synthetic opioid back to a Dallas supply line.
Investigators identified the suspects as 30-year-old Jessica Shirey of Wylie and 32-year-old Joey Jimenez of Dallas. Shirey was taken into custody in late May, Jimenez in June. Detectives allege Shirey handed the fatal dose to the victim and that the drugs were ultimately sourced from Jimenez’s Dallas residence.
How investigators say the case unfolded
The case began on Jan. 31, when Prosper officers responded to a 911 call in the 100 block of West Sixth Street and found an adult man dead inside a home, according to FOX 4. An autopsy later confirmed he died after ingesting a fatal dose of fentanyl.
Detectives say they identified Shirey as the person who directly provided the narcotics to the victim. She was arrested on May 27 and booked into the Collin County Detention Facility. On June 11, investigators executed arrest and search warrants at Jimenez’s Dallas home and took him into custody without incident.
Charges filed under new fentanyl murder law
Prosecutors have filed first‑degree murder charges under Texas House Bill 6, a 2023 statute that treats knowingly manufacturing or delivering fentanyl that results in a death as murder, without requiring proof of an intent to kill. The law, detailed by the Texas Legislature, took effect on Sept. 1, 2023, and has already begun to reshape how some fatal overdose cases are prosecuted in Texas.
“Fentanyl continues to devastate families and communities, and even a small amount can be deadly,” Interim Police Chief Ken Myers said in a department statement reported by FOX 4.
Wider context
Supporters of HB 6 say the law gives prosecutors a clearer path to hold suppliers accountable. A recent report from the House Committee on Criminal Jurisprudence noted that more than 46 people had been charged under the statute by late 2024.
The Drug Enforcement Administration warns that as little as 2 milligrams of fentanyl can be lethal, a point officials often highlight when talking about counterfeit pills and mixed or unknown doses.
Prosecutors across Texas have increasingly pursued fentanyl‑linked murder cases this year. In one example, two suspects were charged in connection with a March 2 fentanyl‑related death in Kyle, Texas, according to KSAT.
What comes next
Shirey and Jimenez remain in custody in Collin County and are awaiting arraignment on first‑degree charges. Prosper police have asked anyone with information about fentanyl distribution in the area to contact the department’s criminal investigations division.
