New details have been released about the circumstances surrounding the death of influencer Emilie Kiser’s son Trigg, including allegations his father, who was looking after him at the time, had placed a $25 bet on an NBA playoff.

Brady Kiser was looking after the three-year-old and the pair’s newborn son Theodore when Trigg was discovered floating in the family pool on May 12.

Social media star Ms Kiser, who is known for her lifestyle content on TikTok, Instagram and YouTube, was out with friends at the time.

A police report into the tragedy obtained by People reveals Trigg was in the pool for about seven minutes before Mr Kiser found him floating unconscious in the water just before 6.40pm.

The toddler died in hospital six days later.

Police initially recommended Mr Kiser be charged with felony child abuse over the drowning death, but Maricopa County attorney Rachel Mitchell later confirmed prosecutors would not be proceeding because there was no “reasonable likelihood of a conviction”.

Mr Kiser told police he lost sight of the toddler for three to five minutes before he found him.

He said Trigg had gone to the backyard after he had finished eating. Mr Kiser said he saw him playing near the pool, which was not unusual, but was “soon distracted” by his newborn.

Mr Kiser told police the next time he saw Trigg, he was in the pool. He jumped in to save him and, distraught, called 911.

Video evidence collected by police cited in the report showed Trigg “was in the backyard unsupervised for more than 9 minutes, and in the water for about 7 of those minutes”.

The toddler did not go into the water intentionally, rather he tripped and fell in while playing with an inflatable chair.

Police also alleged that Mr Kiser had been watching an NBA playoff game and had placed a $25 bet on the outcome around the time of the drowning.

“Brady’s statements do not match what is seen on the video; he did not accurately describe one thing [Trigg] did after he went outside. This leads to the conclusion that Brady was not aware of what [Trigg] was doing and was not watching him,” the police report reads.

“The combination of these factors led to drowning, and a remedy to any of the contributing circumstances could have prevented the outcome.”

Ms Kiser had launched legal action to permanently bar the public release of certain records about Trigg’s death. A court on Thursday ruled in her favour, removing two pages from the Chandler Police Department report.
