Smith Was ‘Very Medicated’ Before Killing McGeehan in Vegas

New details have emerged in the death of 11-year-old Addilyn Smith, whom her mother Tawnia McGeehan allegedly killed.

The cheerleader was allegedly “very medicated” before McGeehan took her life inside a Las Vegas hotel room, according to a Clark County coroner’s investigative report Oxygen obtained.

Investigators found the claim in notes they discovered on a desk in February at the Rio Hotel & Casino, where the mother and daughter died in a murder-suicide.

Smith and McGeehan’s blood contained four medications, including the antipsychotic quetiapine, the antihistamine diphenhydramine, the anticonvulsant gabapentin and the benzodiazepine lorazepam, according to her toxicology report.

McGeehan’s toxicology results also showed sedatives, antidepressants and the presumptive detection of cannabinoids.

According to the coroner’s investigative report, prescription medication bottles were found inside the room, along with an open package of THC cannabis gummies and over-the-counter sleep aids.

The duo, who lived in Utah, were in Nevada to attend a competition for Smith’s cheerleading team. When they didn’t show up and failed to answer the door, Smith’s father called 911 to request a welfare check.

Smith’s cheerleading coach reported the same information to dispatchers, noting that McGeehan did not have full custody of Smith, according to the Las Vegas Review-Journal.

The coach called back later saying that Smith was possibly in “imminent danger,” adding, “Her mom has a bunch of medical issues.”

Police responded, but no one answered the door. Hotel security later entered and discovered McGeehan, with a handgun resting across her chest, and Smith unresponsive in bed.

According to the report, a handwritten note was taped to a chair near the door that read, “Call 911 before walking in. Two dead bodies and one is an 11-year-old.”

“Based on the preliminary evidence at the scene,” police said, “detectives were able to determine the mother shot her daughter before shooting herself.”

The records Oxygen obtained also revealed Smith’s manner of death was homicide. McGeehan’s had been previously ruled a suicide.

McGeehan and her ex-husband had battled for custody of Smith, according to court records the Las Vegas Review-Journal obtained, although it’s unclear what their arrangement was at the time of the deaths.
