Law enforcement officials recently received preliminary toxicology results in the death of Winnemucca Police Department Det. Matt Morgan. 

According to a press release issued by officials July 21, reports from the Washoe County Crime Lab as well as evidence found during the course of the investigation indicate that Morgan ingested two illegal controlled substances that resulted in his death. 

Morgan was found unresponsive at approximately 2:10 p.m. Thursday, June 25 in the WPD evidence vault. Emergency personnel from HGH EMS Rescue, WPD and the Humboldt County Sheriff’s Office responded and determined that Morgan died at the scene. 

At the time of the July 21 press conference, it was unclear if there were video cameras within the vault, a “buddy system” for accessing the vault or other procedures in place. Officials said they will not take additional questions from the media until final toxicology reports are released next month. 

At the time of Morgan’s death, the HCSO/coroner’s office immediately initiated an investigation into Morgan’s cause of death. No evidence of foul play or suicide was found. Deputies’ on-scene investigation revealed a bag containing a white powder that was concealed on Morgan’s person. 

Morgan’s body was transported to the Washoe County Medical Examiner’s Office in Reno. Autopsy results did not reveal a physical cause of death; instead, local investigators were informed they would need to await toxicology results to determine an official cause of death. 

In the week following Morgan’s death, the WPD contacted the Nevada National Guard 92nd Civil Support Team out of Carson City — a military unit that responds to local communities for issues of chemical, biological or radiological hazards. 

Police officials wished to rule out any workplace safety issues within the WPD evidence vault. Until the vault could be cleared, further investigation into Morgan’s activities within the vault were placed on hold. Following a thorough examination on July 2, the 92nd Civil Support Team shared test results on July 7, confirming no workplace safety or hazard issues. 

During a subsequent audit of the WPD’s evidence vault, officers discovered an item of tampered evidence, which has not become part of the HCSO’s continuing investigation. 

The Washoe County Crime Lab found that Morgan had toxic levels of fentanyl — the powdered substance on his person — in his system, along with a second controlled substance, methamphetamine. 

The Humboldt County District Attorney’s Office is expected to review the case once the investigation is complete. 

The WPD and HCSO remain committed to the transparency of the investigation and its results, according to officials. 

They ask that anyone with information that could help can call Secret Witness at 623-6969.
