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.
The Big Horn County Sheriff’s Office extended its gratitude to the various law enforcement and emergency medical teams that responded to this tragic event, including:

Silver Rail Elementary School Shooting Suspect Identified as 16-Year-Old John Griffin, Who was shot and killed by Kaylub Giamanco
BEND, Oregon — The suspect in the deadly shooting at Silver Rail Elementary School in Bend, Oregon, has been identified in preliminary reports as 16-year-old John J. Griffin, according to information provided for this report. Kaylub Giamanco has also been identified in the supplied account as the bystander who reportedly confronted and shot the teenage suspect during the October 15, 2026, incident.
According to a family member who spoke with Channel2 NOW, Giamanco was returning home during his lunch break when he encountered the emergency near the school, where his two daughters reportedly attend classes. He lives nearby and allegedly rushed toward the school after hearing gunshots and realizing that children, including his daughters, could be in danger.
Giamanco’s reported intervention has prompted expressions of gratitude and calls for him to be recognized for his actions. However, the suspect’s identity, Giamanco’s role and the precise sequence of events should be confirmed through official statements before being presented as established facts.
The account provided to Channel2 NOW describes Giamanco as a father who was returning home during his lunch break when the shooting unfolded. After hearing gunfire near Silver Rail Elementary School, he reportedly saw the suspected shooter moving toward or entering the building.
Because his two daughters attended the school, Giamanco allegedly ran toward the scene rather than away from it. Preliminary accounts say he confronted the suspect and shot him, and the 16-year-old reportedly died.
The supplied information does not independently establish the exact location of the confrontation, the actions of those involved immediately beforehand or whether investigators have formally confirmed Giamanco’s identity as the person who shot the suspect.
Nevertheless, the account has drawn strong emotional reactions from people who view his reported actions as an attempt to protect his daughters and other children inside the school.
Some supporters have called for Giamanco to receive a medal or other formal recognition. Any official commendation, however, would need to be confirmed by the relevant authorities.
The supplied report identifies John J. Griffin, 16, as the suspected shooter in the Silver Rail Elementary School attack. The available information describes him as a Bend resident and alleges that a shotgun was used during the incident.
The reported circumstances surrounding Griffin’s death remain an important part of the investigation. Early accounts indicate that a bystander shot the suspect during the emergency, but investigators would need to confirm the individual’s identity and establish the precise sequence of events.
The suspect’s identification and the circumstances of the shooting should be attributed to law enforcement once an official statement is available.
The October 15 shooting prompted a major emergency response and left the community grieving. Preliminary information supplied for this report indicates that four victims—three children and one adult—were killed. The suspected shooter was also reported dead, bringing the reported total to five fatalities.
Five-year-old Rhoam Summer was identified in the supplied information as the first named victim. Two other children, reportedly ages 8 and 11, were also described as having died. An adult teacher was reported among the victims.
Two additional people—a 7-year-old child and a 54-year-old teacher—were reportedly transported for medical treatment in critical condition.
The identities of the other victims, the final casualty figures and the latest conditions of the injured people require confirmation from law enforcement or the appropriate authorities. The information available for this article does not establish that the teacher who died was killed while protecting students, so that characterization should not be presented as confirmed.
Bend police reportedly issued an active-shooter alert at approximately 1:17 p.m. on Thursday, warning the public of a major law enforcement presence at Silver Rail Elementary School and urging people to avoid the surrounding area.
Police, firefighters and emergency medical personnel responded to the campus. Nearby schools, including Caldera High School and Jewell Elementary, were reportedly placed under lockdown as a precaution.
Authorities also designated Journey Church, located at 61303 S Highway 97 near Goodwill and Dairy Queen, as a family reunification location. Parents and guardians were directed there to reconnect with students and receive information during the emergency response.
The reported deaths of children and an adult educator have left families and the wider Bend community facing an immense tragedy. Rhoam Summer, just 5 years old, has become one of the first children named in the reports surrounding the shooting.
As the investigation continues, families are waiting for verified information and the opportunity to grieve their loved ones. Those affected by the shooting may also face a difficult period of emotional recovery.
Giamanco’s reported actions have added another dimension to the story, with supporters expressing gratitude for a father who allegedly rushed toward danger after hearing gunshots near the school attended by his daughters. His family’s experience and the well-being of his children also deserve consideration as details emerge.
🙏💔 Our thoughts are with the families of Rhoam Summer and the other reported victims, the injured child and teacher, and everyone affected by this devastating incident. May those who lost their lives rest in peace, and may their loved ones find strength and support during this heartbreaking time.
