A MOM who killed her 11-year-old daughter before taking her own life left a note warning whoever entered their Las Vegas hotel room, newly released records reveal.

Tawnia McGeehan, 34, and her daughter Addilyn “Addi” Smith were found dead together at the Rio Hotel & Casino in February.

Their deaths came after McGeehan had been embroiled in a bitter nine-year custody battle with Addi’s father, Bradley Smith.

Now, newly released coroner records have revealed disturbing details about what investigators discovered in the hotel room and the hours leading up to their deaths.

Investigators found multiple handwritten notes, including one taped to a chair positioned behind the hotel room door.

“Call 911 before walking in. Two dead bodies and one is an 11-year-old,” the warning read.

Two other handwritten notes were also discovered in the room, according to reports citing the Clark County Coroner’s Office investigation.

They indicated Addi had been “very medicated” before she was killed and that the pair had slept cuddled together.

Another message indicated Addi’s phone had been left unlocked so loved ones could access the youngster’s photos and videos.

Toxicology testing detected caffeine, quetiapine, diphenhydramine, gabapentin and lorazepam in Addi’s system.

McGeehan tested positive for several of the same substances as well as cannabinoids and other medications.

Investigators searching the room also recovered prescription bottles bearing McGeehan’s name, over-the-counter sleep aids and an opened packet of THC cannabis gummies.

They also found what appeared to be broken and mostly open gabapentin capsules and a clear cup containing white residue in a trash can.

The findings shed new light on the February murder-suicide that stunned the young cheerleader’s family and community.

McGeehan and Addi had traveled from Utah to Las Vegas on February 13 for a cheerleading tournament where Addi was due to compete with Utah Xtreme Cheer.

But concern grew when the youngster failed to appear at the competition and her family could not get hold of the mother and daughter.

Addi’s father and cheer coach were among those who contacted authorities seeking welfare checks.

Police went to the hotel and knocked on the room door but received no response, with cops later saying there was not enough information at the time to believe either was in danger.

After further calls raising concerns for Addi’s safety, hotel security entered the room and discovered mother and daughter lying together on one of its two beds.

Addi was wearing pajamas and had a pillow placed over her face, according to the newly released investigative report.

The pillow had a bullet hole through it, while McGeehan was found alongside her daughter with a semi-automatic handgun on her chest and face area.

Investigators also reportedly found two cartridge casings on the floor and another beneath McGeehan’s body.

Authorities determined McGeehan had fatally shot Addi before turning the gun on herself.

The Clark County Coroner’s Office found both mother and daughter died from gunshot wounds to the head, ruling Addi’s death a homicide and McGeehan’s a suicide.

The investigative report did not identify a motive for the murder-suicide.

Family members told investigators McGeehan had a history of severe depression and previous suicidal thoughts, but said they were unaware of any previous attempts, according to the coroner’s report.

McGeehan and Smith’s lengthy custody battle began after they filed for divorce in 2015, with their split finalized two years later.

In 2020, a family court temporarily restricted McGeehan to supervised visits after finding Smith better understood Addi’s “physical and emotional needs.”

Family Court Commissioner Marian Ito wrote that McGeehan “has committed domestic abuse in the presence of the minor child,” although the order did not specify who had been abused.

The commissioner also found McGeehan had subjected Addi to “parental alienation” and said her ability to parent alongside Smith was “seriously in question.”

However, their custody arrangement later changed and the years-long battle ended in 2024 when both parents were deemed fit, subject to a lengthy list of rules while caring for Addi.

Those conditions included requiring custody exchanges to take place at school or a local police department, with the parents ordered to park five spaces apart and banned from filming the handovers.

They were also ordered to speak respectfully about one another and not alienate Addi from either parent.

Addi’s cheerleading team, Utah Xtreme Cheer, paid an emotional tribute to the 11-year-old following her death.

“We are completely heartbroken. No words do the situation justice,” the team said.

“She was so beyond loved, and she will always be a part of the UXC family.”
