A mother accused of killing her 11-year-old daughter before taking her own life during a Las Vegas cheer competition had several medications in her system, while cannabis gummies and prescription bottles were found in their hotel room.
The deaths of Tawnia McGeehan and her daughter, Addi Smith, were recorded by the Clark County Medical Examiner as resulting from gunshot wounds to the head.
McGeehan’s former husband contacted police in February 2026 after he was unable to reach the pair. Staff at the Rio Hotel then went to their room, where they found a note outside warning: “Call 911 before walking in. Two dead bodies and one is an 11-year-old.”
Hotel staff found McGeehan and Addi in a bed. Officers later discovered two suicide notes, including one which said Addi had been “heavily medicated” beforehand.
Prescription bottles and THC gummies found in room
Police found several prescription bottles belonging to McGeehan, an open packet of THC cannabis gummies and bottles of over-the-counter sleep aids.
They also reported finding what appeared to be broken and mostly empty gabapentin capsules, along with a clear cup containing white residue near a bin.
Cartridge casings were found on the floor beside a Ruger handgun. The medical examiner’s report said McGeehan tested positive for medicines used to treat depression, insomnia and anxiety.
The report noted that McGeehan had a history of severe depression and had previously been prescribed medication for the condition. It said those close to her were aware of past suicidal thoughts but did not know of any previous attempts.
An officer recorded that McGeehan had reportedly been severely depressed over break-ups and an ongoing custody dispute with her former husband.
