Before Kaitlin Armstrong was found guilty of killing professional gravel cyclist Anna Moriah "Mo" Wilson, she was on the run in Costa Rica from the murder charge.But when investigators went to look for her, she was nowhere to be found. The Lone Star Fugitive Task Force got the job of tracking her down. They suspected Armstrong had flown to Costa Rica on May 18, 2022. There, she tried to hide her identity by using other names, Beth and Ari, and she cut and dyed her hair.
"48 Hours" contributor Jonathan Vigliotti has the first interview with members of the task force in "Capturing Moriah Wilson's Killer."
