Matt Baker, a charismatic minister in Hewitt, Texas, appeared to have it all—his marriage to Kari, a Sunday school teacher, and their two young daughters made them seem like the picture-perfect family. But when Kari was found dead in the family home, initially ruled a suicide, the carefully constructed façade began to crumble. Over time, Kari’s family became suspicious and started their own investigation into her death, convinced that foul play was involved.

20/20 uncovers never-before-seen emails between Matt and Kari that reveal troubling details about their relationship. Through exclusive interviews with Kari’s mother, Linda Dulin, and other family members—whom they call the “Charlie’s Angels” of Waco—Quiñones examines their tireless efforts to get to the truth. The episode also features interviews with key law enforcement figures, including investigator Abdon Rodriguez and former Texas Ranger Matt Cawthon, who played a crucial role in getting Kari’s body exhumed and reexamined, leading to critical new evidence.

Tune in to 20/20 this Friday, March 21, at 9:01 PM EDT for this gripping investigation into a shocking crime and the relentless pursuit of justice. The episode will also be available for streaming on Hulu the next day.
