Brady Kiser, the husband of influencer Emilie Kiser, reportedly placed a wager on an NBA playoff game an hour before the drowning death of their 3-year-old son, Trigg, according to a Chandler Police Department report.

Brady, 28, reportedly had his attention "divided" between watching his two young sons and Game 4 of the Eastern Conference Semifinals between the Boston Celtics and New York Knicks on May 12, having placed a $25 bet on DraftKings sportsbook 75 minutes before his son was spotted outside on a security camera. Trigg was reportedly unsupervised in the family's backyard for nine minutes and "in the water for seven of those minutes," the Chandler Police Department report, which was first obtained by PEOPLE and shared publicly on Friday (August 8), states.

Brady reportedly bet on Celtics star Jayson Tatum to score 40+ points, with Tatum finishing with 42 in the 121-113 loss to the Knicks, which paid out $102.50.

Last month, the Maricopa County Attorney's Office announced that Brady wouldn't be charged in his son's death. Local authorities previously recommended a Class 4 felony charge of child abuse against Brady, however, an investigation by the Maricopa County Attorney's Office determined that there was insufficient evidence against him.

“Maricopa County Attorney Rachel Mitchell announced today that Brady Kiser will not be charged in the drowning death of his son because there is no reasonable likelihood of conviction,” the Maricopa County Attorney's Office said. “Surveillance video from outside the home showed how the drowning occurred and the actual timeline of events.”

“In order to convict a person of this charge, the state has to prove beyond a reasonable doubt to a unanimous jury that the person failed to perceive a substantial and unjustifiable risk, and that failure to perceive the risk was a gross deviation from the standard of care a reasonable person would show,” the statement added.

“After careful review of the evidence submitted by Chandler PD, it was determined this case does not meet that standard,” the office continued. “Given a court order, no additional details can be discussed at this time.”

In May, Emilie Kiser, who wasn't home at the time of her son's drowning, filed a lawsuit against multiple Maricopa County public offices amid an ongoing investigation into his death.

"With her motion, Emilie Kiser is urging the court to keep private the footage and records related to her young son’s death - a deeply personal, and reasonable, plea to prevent the public release of the most traumatic moment of her life," the source told PEOPLE.

More than 100 public records requests were filed with the city of Chandler and Maricopa County Medical Examiner's Office since the news of Trigg's death, which was ruled as accidental, according to the lawsuit. Kiser, however, was reported to have never viewed any records requested, the police report, security camera footage, body camera footage or autopsy reports.

Trigg was initially found unresponsive and succumbed to injuries that had previously left him hospitalized in critical condition on May 12. Authorities said they wouldn't release any additional details about the child's condition out of respect to the Kiser family's privacy while extending their sympathies publicly amid the ongoing investigation.
