PROSPER, Texas — Prosper police have arrested two North Texas residents on murder charges following an investigation into a fatal fentanyl poisoning that claimed the life of a Prosper man earlier this year.
Officers responded on Jan. 31, 2026, to a residence in the 100 block of West Sixth Street after receiving a 911 call reporting a possible overdose. Upon arrival, officers found an adult male deceased inside the home.
An extensive investigation by the Prosper Police Department's Drug Interdiction and Criminal Enforcement Unit determined the victim died after ingesting a fatal dose of fentanyl.
Detectives identified 30-year-old Jessica Shirey of Wylie as the person who allegedly provided the fentanyl that led to the victim's death. Investigators obtained an arrest warrant, and Shirey was taken into custody on May 27, 2026. She was booked into the Collin County Detention Facility on a murder charge.
As the investigation continued, detectives determined Shirey had allegedly obtained the fentanyl from 32-year-old Joey Jimenez of Dallas.
On June 11, Prosper detectives, assisted by the Dallas Police Department, executed arrest and search warrants at Jimenez's residence in Dallas. Authorities said Jimenez was taken into custody without incident and transported to the Collin County Detention Facility, where he was also booked on a murder charge.
"Our hearts remain with the victim's family and loved ones as they continue to cope with this tragic loss," Interim Police Chief Ken Myers said in a statement. "Fentanyl continues to devastate families and communities, and even a small amount can be deadly. The Prosper Police Department is committed to aggressively investigating these cases and holding those responsible accountable under the law."
Under Texas House Bill 6, which took effect Sept. 1, 2023, individuals can be charged with murder if they knowingly manufacture or deliver fentanyl that results in another person's death. The law does not require prosecutors to prove the accused intended to cause the death. The offense is classified as a first-degree felony.
Prosper police encouraged anyone with information regarding the sale, distribution or possession of fentanyl and other illegal narcotics to contact the department's Criminal Investigations Division.
The investigation remains ongoing.
