Wyoming Tragedy: 3 children killed, 1 fighting for life after Byron shooting
Sources confirmed woman shot and killed her children – All under age of 10
Byron, WY – February 10, 2025 – The Big Horn County Sheriff’s Office (BHCSO) has confirmed a tragic shooting incident that took place at a residence on the 200 block of East Shoshone Avenue in Byron, Wyoming.
At approximately 1:30 p.m., the BHCSO Public Safety Communications Center received a 911 call from a female identified as Tranyelle Harshman, who reported that multiple gunshots had been fired inside her home.
Harshman informed dispatchers that her four daughters had been shot, and when asked about their condition, she stated that she believed they were deceased.
During the emergency call, Harshman provided the locations of the victims, stating that two of the children were in their cribs upstairs, while the other two were in their shared bedroom downstairs.
She also told dispatchers that she was in her upstairs bedroom and expressed an intent to harm herself.
Despite the dispatcher’s efforts to keep Harshman on the line and de-escalate the situation, she repeatedly stated that it was “too late” and ultimately disconnected the call.
Following the distressing call, BHCSO immediately dispatched multiple law enforcement units to the scene, including mutual aid resources from the Lovell Police Department and Wyoming Highway Patrol.
Emergency medical personnel from North Big Horn Hospital District and Powell Valley Healthcare were also mobilized and staged in the area in preparation for critical care interventions.
Law enforcement officers arrived on the scene within minutes and promptly entered the residence.
Upon conducting a tactical search, officers discovered a horrific scene:
- Two female children, aged 2 and 9 years old, were found deceased with gunshot wounds to the head.
- Two other female children, aged 2 and 7 years old, were still alive despite sustaining gunshot wounds to the head.
- A 32-year-old female, later identified as the caller, Tranyelle Harshman, was located in an upstairs bedroom with a self-inflicted gunshot wound to the head. Despite her injuries, she showed signs of life.
Responding officers provided immediate lifesaving first aid before ambulance personnel arrived to administer advanced life support:
- The 7-year-old girl, who remained alive at the scene, was urgently transported to North Big Horn Hospital before being airlifted via Cody Regional Health-First Flight of Wyoming to receive specialized critical care.
- The 32-year-old Harshman was also transported to North Big Horn Hospital, where she received advanced life support before being transferred to a higher-level care facility.
- Tragically, the 2-year-old girl who initially showed signs of life succumbed to her injuries shortly after emergency personnel arrived.
At the time of this release, the medical conditions of the surviving victims remain unknown.
The Big Horn County Sheriff’s Office, assisted by the Wyoming Division of Criminal Investigations, remained on the scene into the early morning hours of February 11, 2025, processing evidence and conducting an extensive investigation.
The Crime Scene Investigations Unit from Cheyenne, Wyoming, along with Special Agents from the Northwest Enforcement Team in Cody, Wyoming, were deployed to aid in forensic processing.
Authorities have confirmed that this was an isolated incident contained within the residence, and there is no ongoing threat to the public.

MT. JULIET, Tenn. — Authorities have identified two victims killed during an active shooter incident at Cedar Creek Marina in Mt. Juliet late Friday night.
The suspect, identified as Gary Haley, a convicted felon with an extensive criminal history, is deceased following an officer-involved shooting, officials confirmed.
Mount Juliet Police officers were dispatched at approximately 9:30 p.m. Friday to the Cedar Creek Marina, located in the 9000 block of Saundersville Road, after receiving reports of a man threatening another individual on the docks.
Due to the active shooter report, a shelter-in-place order was issued for the surrounding area as a precaution.
Upon arrival, officers located an adult male suffering from a gunshot wound.
The victim was later identified as Robby Brogdon, who was transported to a local hospital for emergency medical treatment.
Despite life-saving efforts, Brogdon later succumbed to his injuries.
Investigators determined that the suspected shooter had retreated to a boat within the marina and had barricaded himself inside.
The standoff continued for several hours as officers secured the scene and attempted to resolve the situation safely.
At approximately 1:00 a.m. Saturday, the Tennessee Bureau of Investigation (TBI) reported that the suspect engaged responding officers and fired shots at them under circumstances that remain under investigation. Officers returned fire.
The suspect, Gary Haley, was later found deceased aboard the vessel.
During the course of the response, officers also discovered a second adult male victim, Nathan Jones, who had been shot by the suspect.
Jones was pronounced dead at the scene.
No law enforcement officers were injured during the incident.
The Tennessee Bureau of Investigation has assumed responsibility for the investigation, which includes a homicide, an attempted homicide, and an officer-involved shooting.
TBI agents are actively conducting interviews, collecting evidence, and working to establish a comprehensive timeline of events.
Upon completion of the investigation, findings will be submitted to 15th Judicial District Attorney General Jason Lawson for review.
