A Utah dance mom gave her 11-year-old daughter a cocktail of prescription medications before shooting the girl and herself in a grisly murder-suicide, new toxicology results reveal.
Tawnia McGeehan, 34, and her daughter, Addilyn Smith, were found dead from gunshot wounds after police were called to perform a welfare check at the Rio Hotel and Casino at Las Vegas, where the pair had been traveling for Smith’s cheer competition in February.
Newly released toxicology results show that the mother-daughter duo had ingested a myriad of drugs before the gunfire erupted.
Substances including quetiapine, an antipsychotic medication; gabapentin, an anticonvulsant drug; the anxiety drug lorazepam and the antihistamine diphenhydramine were all present in Smith’s system when she died, according to autopsy reports from the Clark County coroner obtained by News 3.
McGeehan’s toxicology report listed the same drugs, as well as eszopiclone or zopiclone, a prescription sedative; the antidepressant drug known as citalopram or escitalopram, as well as cannabinoids.
Caffeine was also presumably detected in both toxicology reports, the outlet reported.
After ingesting the meds, McGeehan fatally shot her daughter in the head before turning the gun on herself.
Handwritten notes found inside the hotel room stated the youngster had been “very medicated” leading up to her death, according to the coroner’s investigative report.
