When 21-year-old Kelsie Schelling stopped answering her phone on Feb. 5, 2013, her family and friends began to wonder where she could be.
"We tried calling her … couldn't get a response," Savannah Heggie, who was Schelling's supervisor at the home goods store she worked at, told ABC News' "20/20."

Schelling's father, Doug Schelling, also tried desperately to reach his daughter, who was living in Denver at the time.
"She didn't answer her phone, which is kind of pretty rare," Doug Schelling told "20/20."
Schelling is a vivacious young woman, who likes to have fun and laugh, those who know her say, and is loved by her family, friends and her dog name Karmi.
Police say that on Feb. 4, 2013, Schelling went to Pueblo, Colorado, to meet her boyfriend, Donthe Lucas. Schelling was eight weeks pregnant.
"The whole world just unraveled. All of her friends, like, started contacting us saying, you know, 'We've been trying to reach Kelsie and we can't reach her.' And when that happened, that is, like, when I got really, really scared," Schelling's mother, Laura Saxton, told "20/20."
More than three years later, family and friends are searching for answers to what happened to Schelling.
Her mother has publicly criticized the Pueblo Police Department, which she says botched the investigation and left her and her family holding the bag.
"It's unbelievable to me. I mean, I can't believe it's me doing all of the things that I'm doing to just, you know, get out and fight people like I have," said Saxton.
