Knabel went missing on Aug. 13, 2019. She was last seen leaving her sister Erin's house early in the morning to make the mile-long walk back to their mother's Louisville home, where she was staying. While Knabel's family continues searching for the 39-year-old, they are also making sure to help care for her sons, ages 8 and 10, who are living with their fathers. "They're very strong boys and very bright," Erin Knabel says of her nephews in this week's issue of PEOPLE. "They're doing the best they can really, but they're very sad. They miss their mom." Initially, police and Knabel's family believed the then–37-year-old disappeared while walking to her mother's house, however, a private investigator hired by Knabel's family discovered that her phone's GPS located her at her mother's home in the middle of the night.
