[Florida Files] The Murder of Shanti Cooper-Tronnes

A Dream Home That Became a Financial Strain

Shanti Cooper-Tronnes had built a successful consulting business and a life centered on her son, Jackson. In 2013, she met David Tronnes through Match.com, and their relationship moved quickly. He relocated from Minnesota to Orlando, and the couple married in 2017. By then, they were already years into a renovation they hoped would give them a dream home.

The property in Orlando’s Delaney Park neighborhood had become a costly, unfinished project. As construction made the main house unlivable, Shanti and Jackson moved into a small apartment above the garage, where she also ran her business. David slept downstairs with the dogs. Shanti had contributed substantial money to the renovation, but her name was not on the deed, leaving her worried about what would happen to her investment.

David hoped the reality series Zombie House Flipping could help them finish the work. Prosecutors later argued that Shanti’s reluctance to participate threatened that plan, although testimony differed on whether she wanted to appear on the show. The renovation, the financial pressure, and the couple’s disagreements would all become part of the murder investigation.

The Bathtub Story and the Evidence That Challenged It

On April 24, 2018, David called 911 and reported finding Shanti unresponsive in the bathtub. He suggested a fall or medical emergency, but investigators immediately questioned his explanation. The dry bathroom floor did not match his description of pulling her from a nearly full tub, and an autopsy determined that she had died from blunt force trauma and strangulation.

In this episode of Moms and Mysteries, Mandy and Melissa follow the detectives’ questioning, the blood found near Shanti’s bed, and the competing explanations for what happened. They also discuss the defense’s arguments, the delays that kept the case from reaching trial for more than five years, and the financial disputes that continued after Shanti’s death.

On October 18, 2023, a jury found David Tronnes guilty of first-degree murder, and he was sentenced to life in prison. At sentencing, Jackson spoke about the mother he had lost when he was only eight. Beyond the unfinished house and the courtroom evidence, Shanti’s story is about a hardworking woman, a devoted mother, and a family living with her absence.
