LEXINGTON, N.C. (WGHP) -- Thursday marks 30 years since Debra Asbury disappeared from her home in Lexington. Three decades later, her family is still searching for answers. Courtney Patterson, Debra’s daughter who was two years old at the time, says the pain of not knowing where her mother went is still just as fresh as the first day she found out. Patterson says that’s never stopped her from looking for answers. “According to my aunt who was living in the house, she had come back home, and she changed her clothes, and she told my aunt that she was leaving. When my aunt woke up several hours later, my mom was gone, but all of her belongings were left on the counter,” Patterson said. She didn’t find out her mother was a missing person until she turned 15. “It was never really talked about ...When I actually found out she was a missing person, it was because I had met my mom's side of the family,” Patterson said. From that moment on, Patterson made it her mission to find out what happened to her mother. “Mom's side of the family did it for as long as they could. They got burnt out,” Patterson said. Patterson says she’s tried every possible option by using her time and energy talking to family members who remember that time, speaking with police and doing her own digging. She’s even put her DNA in the National Missing and Unidentified Persons System. “Even if they were to find ... remains, they can still test it with that,” Patterson said. She has kept a binder full of every piece of information she’s found over the years. Patterson is still hopeful for answers even if they aren’t the ones she wants. “I honestly don’t think that she’s alive ... If that’s the case, she at least deserves us to be able to put her to rest,” she said. Heading into the third decade of this case being unsolved, one thought is still the same. “I wonder what it would be like if she was here,” Patterson said. The Lexington Police Department is the lead department on this case. It remains open as a cold case. Investigators have never been found any remains related to Debra Asbury.
