On a July morning in 2014, Florida State University law professor Dan Markel was shot in the garage of his Tallahassee home. It was no robbery — it was targeted, and the trail led to his ex-wife's own family. It would take eleven years, and one manufactured moment, to pull the truth loose.

This is the story beneath the headline: the custody fight, the hired men traced through a silver Prius and a toll transponder, the money that ran through one woman, and the FBI "bump" that finally cracked a wall of wealth and lawyers.

Sigfredo Garcia, the gunman, was convicted in 2019; Katherine Magbanua in 2022; Charlie Adelson, the dentist prosecutors said organized it, in 2023; and in 2025 the matriarch, Donna Adelson, was convicted and sentenced to life plus thirty years. She is appealing; the conviction stands. Wendi and Harvey Adelson were never charged and deny any involvement. Dan Markel's mother, Ruth, spent years fighting for the right to see her grandsons — and Florida changed its law because of it.
