Polk County Sheriff Byron Lyons launched a comprehensive training initiative in 2023, requiring all patrol deputies and detectives to complete in-service training, covering case law, agency policy, and first responder medical care.
As part of this program, each patrol vehicle is equipped with a medical kit designed to address overdose emergencies and “stop the bleed” situations, enabling deputies to provide critical care prior to the arrival of emergency medical services. The program has proven highly effective, with multiple incidents where deputies successfully rendered lifesaving aid in cases involving overdoses, choking, and severe bleeding.
In October of 2025, the sheriff’s office responded to a critical incident on Wilson Road involving a gunshot victim. Upon arrival, Detective Kayla Hemperly, Detective Francisco Segura, and Trooper Simon Mijares demonstrated exceptional composure and lifesaving skill under extreme conditions. Their actions, medical training, and coordinated teamwork were instrumental in stabilizing the victim.
Medical professionals later confirmed that the immediate care provided by Detectives Hemperly, Segura and Trooper Mijares significantly increased the victim’s chances of survival. The officers administered treatment while under guard maintaining scene security, as additional personnel worked nearby to locate an armed suspect whose whereabouts were unknown at the time.
In recognition of their efforts, all three officers were awarded the State of Texas Director’s Award for Lifesaving from the Texas Department of Public Safety, as well as the Lifesaving Award from the Polk County Sheriff’s Office.
Lyons reaffirmed his commitment to serving the Polk County community through continued investment in advanced training and resources, ensuring sheriff’s office personnel are fully prepared to protect and preserve life on any call. Lyons personally thanked all three officers for their professionalism, swift actions, and will to do the job.
