A HAPPILY MARRIED WISCONSIN COUPLE SUDDENLY DISAPPEARS - POLICE TURN TO SNAPCHAT FOR ANSWERS

"48 Hours" Investigates in "The Snapchat Clue"

Bart and Krista Halderson had a beautiful home in Windsor, Wis., and two adult sons they adored, so when Bart and Krista suddenly disappeared in July 2021, it stunned their community. 48 HOURS correspondent Erin Moriarty investigates how information found on social media would lead investigators to their killer in "The Snapchat Clue," to be broadcast Saturday, Nov. 5 (10:00 PM, ET/PT) on the CBS Television Network and streaming on Paramount+.

Mystery surrounded the couple's disappearance and investigators immediately turned to family members for information, including sons Mitchell, who was 24 at the time and worked in tech, and Chandler, then a 23-year-old college student living at home. Chandler was excited about a new job offer he said he had with Elon Musk's SpaceX. It was Chandler who told police his parents had gone to the family cabin for the July 4 holiday weekend and never returned. Then, police would finally find a clue in the most unlikely place - the social media app Snapchat.

"No way would I have ever, ever guessed what was about to be revealed. Never," Krista Halderson's cousin Barbi Townsend said. "Nobody saw this coming."
