On May 23, 2016, Hailey Burns, then just 16 years old, walked out of her home in North Carolina and vanished.
Her mother had checked all the doors the night before, ensuring they were locked. But when Hailey’s family went to wake her for school, she was gone.
The front door to the family’s home was wide open.
"It was the worst feeling you could ever imagine. You feel completely out of control. You don't know what to do," her father, Tony Burns, told WCNC News in the wake of her disappearance.
"You just panic."
A nationwide search for Hailey began, as her family revealed she had Asperger's Syndrome and had left home without any of her medication.
Despite the family's attempts to limit the teen's use of computers, searches revealed she had been speaking to strangers online.
Investigators believed she had left home to meet a person she had met via social media.
