A routine cheerleading competition trip to the Rio Hotel & Casino turned into one of the most heartbreaking tragedies to hit the youth sports community this year when 38-year-old Tawnia McGeehan fatally shot her 11-year-old daughter, Addilyn “Addi” Smith, before taking her own life on February 15, 2026.

Las Vegas Metropolitan Police Department (LVMPD) homicide detectives confirmed the deaths as a murder-suicide after responding to welfare check requests from worried family members. The pair, from West Jordan, Utah, had traveled to Las Vegas for a cheer event with Utah Xtreme Cheer but never checked in or appeared at the competition, sparking alarm.

Authorities discovered the bodies in their hotel room Sunday afternoon. A handwritten suicide note was recovered at the scene, with investigators revealing its final, haunting line: “She must be mine.” The note’s contents have not been fully released publicly, but sources close to the investigation described it as laying bare McGeehan’s despair in her last moments. Police have not officially disclosed a motive, though family members and court records point to a volatile mix of long-standing issues.

McGeehan, described by relatives as a devoted but struggling mother, had been locked in a contentious custody battle with Addi’s father, Bradley Smith, for nearly a decade following their divorce. Court documents from Utah, obtained by multiple outlets including KSL.com and KUTV, detail years of disputes over custody arrangements, visitation rules, and allegations of interference. In one instance around 2020, a judge temporarily modified custody after finding McGeehan had acted in ways that alienated the child from her father. The battles reportedly eased in 2024 when a final resolution was reached, granting joint custody and decision-making rights.

Despite the apparent resolution, tensions lingered. McGeehan’s mother, Connie McGeehan, told reporters her daughter had recently faced harsh messages from other parents on the cheer team. “They were texting [Tawnia] mean stuff and blaming Addi,” Connie said, suggesting the pressure from the competitive cheer world contributed to her daughter’s emotional state. Connie added that Tawnia had long battled depression but appeared to be improving before the trip.

The cheer community in Utah was devastated. Utah Xtreme Cheer issued statements mourning Addi, calling her a bright, talented athlete with a infectious smile. A GoFundMe page was quickly established by family and friends to cover funeral expenses and support Addi’s father and extended relatives, raising funds amid an outpouring of condolences from teammates, coaches, and parents across the state.

The sequence of events unfolded rapidly. Family members, concerned after losing contact, repeatedly called Las Vegas police and fire departments for welfare checks. Officers initially responded but did not force entry into the room. Hours later, hotel security assisted in gaining access, where they found both victims deceased from gunshot wounds. The Clark County Coroner’s Office ruled McGeehan’s death a suicide and confirmed she shot Addi before turning the weapon on herself. Addi’s official cause and manner of death were pending further review as of late February.

The case has reignited discussions about mental health in high-pressure youth sports environments, where parents often invest heavily in competitions, travel, and performance. Cheerleading, with its intense routines and rivalries, can amplify stress, especially amid family conflicts. Experts note that custody disputes can exacerbate underlying mental health issues, though no direct link has been confirmed in this case.

LVMPD Lt. Robert Price described the incident as “sad and tragic,” extending sympathies to the family. Investigators interviewed witnesses, reviewed hotel security footage, and processed the scene, but declined to release more details about the note or potential triggers beyond what has emerged publicly.

Addi was remembered fondly by those who knew her. Photos shared by family and her cheer gym show a young girl with long hair, often in sparkly uniforms, posing with trophies or mid-routine. Teammates recalled her energy and kindness, while coaches highlighted her dedication. The loss has left the Utah cheer scene in mourning, with vigils planned and ribbons displayed at upcoming events.

For Bradley Smith, Addi’s father, the tragedy compounds years of legal and emotional strain. He has remained largely out of the public eye, but family statements express profound grief. The stepmother reportedly made desperate pleas for information in the hours before the bodies were discovered, highlighting the confusion and panic that preceded confirmation.

The Rio Hotel & Casino, a popular spot off the Strip for events and tournaments, has cooperated fully with police. No other guests or staff were involved, and the incident appears isolated to the room.

As the investigation continues, questions linger about warning signs. Family members noted McGeehan had seemed upbeat at times, but underlying struggles persisted. The single line in the note—”She must be mine”—has fueled speculation about possessiveness tied to custody fears or deeper psychological distress, though authorities caution against drawing firm conclusions without full context.

This case joins a string of heartbreaking family tragedies involving firearms and mental health crises. In Utah and Nevada, officials have urged greater awareness of resources for parents in high-conflict situations and those battling depression. Hotlines and support services remain available for anyone in crisis.

The cheer world, often seen as glamorous and energetic, now grapples with a darker reality. Addi’s story serves as a stark reminder that behind the routines and cheers, families can carry unseen burdens. As the community heals, tributes continue to pour in for a young life cut short and a mother whose final act has left an indelible scar.
