Seven months after Tawnia McGeehan and her 11-year-old daughter Addilyn Smith were found ᴅᴇᴀᴅ in a Las Vegas H๏τel, newly released toxicology records have added another layer to an already complicated case.

The mother and daughter had traveled from Utah to Las Vegas for a cheerleading event in February. They did not appear at the compeтιтion, and attempts to reach them failed. After Addi’s father requested a welfare check, authorities eventually entered the H๏τel room and found both victims ᴅᴇᴀᴅ.

At the time, investigators said McGeehan had killed her daughter and then herself. The newly released Clark County coroner documents now provide additional information about substances found in their systems, handwritten notes recovered from the room and the family history investigators documented.

The toxicology results showed that Addi had several medications in her system. Among them were quetiapine, gabapentin, lorazepam and diphenhydramine. The report also documented substances found in McGeehan’s system, including several of the same medications, along with a prescription sleep medication, an antidepressant and cannabinoids.

The presence of these substances has received considerable attention because investigators also found a handwritten note stating that Addi had been heavily medicated before her death. However, the coroner’s conclusion is important: the cause of death for both mother and daughter was listed as gunsH๏τ wounds. The toxicology findings were part of the investigative record but were not identified as the causes of death.

The reports also provide insight into what investigators learned about McGeehan before her death. According to information supplied by relatives, she had a history of severe depression and had previously been prescribed medication for it. Family members also reported that they knew of past suicidal thoughts but said they did not know of previous suicide attempts.

The report referenced relationship difficulties and the long-running custody dispute involving Addi’s father, Bradley Smith. It described McGeehan as having been severely depressed over breakups and the continuing custody conflict. The coroner’s documentation, however, does not establish that any single event was the definitive cause of the tragedy.

That distinction has become increasingly important as additional details have emerged. The case contains information from several different sources: court documents, police records, coroner findings, toxicology testing and statements from relatives. Each source addresses a different part of the story.

The custody history predates the Las Vegas incident by years. In 2020, court records described serious concerns about McGeehan’s parenting and temporarily restricted her to supervised visitation. The court also found that she had committed domestic abuse in the presence of the child. By 2024, however, the custody arrangement had changed substantially, with the parents receiving joint legal and physical custody and McGeehan receiving presumptive decision-making authority over several major issues involving Addi.

The contrast between those court orders and the events of 2026 has become a major part of public discussion surrounding the case. But the documents should be read chronologically. The 2020 court order reflected information available to the court at that time, while the 2024 order represented a later legal determination under different circumstances. Neither order was written with knowledge of what would happen in Las Vegas two years later.

The toxicology findings also show why the final hours cannot be reconstructed from a single piece of evidence. Medication results reveal what substances were present in the bodies, while the handwritten notes reveal what investigators say McGeehan intended to communicate. The physical scene establishes how authorities found the victims. Court documents provide the longer background.

Investigators also documented prescription bottles and other items inside the H๏τel room. The scene included evidence that McGeehan had been using medications and that the mother and daughter had spent their final hours together in the room.

The timing of the discovery has also become clearer. KSL reported that the first welfare check occurred around late morning after the pair failed to appear at the compeтιтion. Police initially did not enter. A later call was received during the afternoon, and H๏τel security subsequently entered the room. Officials were notified later that day, and the victims were pronounced ᴅᴇᴀᴅ that evening.

For Addi’s family and friends, the forensic findings are difficult to separate from memories of an 11-year-old who had traveled to Las Vegas for a compeтιтion. Her cheer organization publicly mourned her, describing her as deeply loved and emphasizing the impact of her death on the team.

Meanwhile, Connie McGeehan has focused on preserving memories of the mother and daughter outside the circumstances of their deaths. In recent interviews, she described family outings, traditions and ordinary moments shared by Tawnia and Addi. She has also shared older videos of the pair together.

The new toxicology findings therefore answer some questions but create a more detailed picture of the circumstances rather than a single explanation. They show what substances were detected, what investigators found at the scene and what relatives told authorities about McGeehan’s history. They do not independently establish why the tragedy happened.

That distinction is likely to remain important as the case continues to be discussed. The official records provide a clearer account of the evidence, but the personal and legal history surrounding the family remains much larger than the final day in Las Vegas.
