Summary based on the NamUs case record (MP67728) and 2 other sources
In the winter of 2020, a family's life was forever altered when 17-year-old Kylie Dawn Lehenbauer vanished from her home in Newalla, Oklahoma. On February 11, 2020, the teenage girl was last known to be in her residence in Oklahoma County. At the time of her disappearance, Kylie was described as a female with red or auburn hair and hazel eyes, standing at 5 feet 4 inches and weighing approximately 110 pounds. The days that followed her last sighting were filled with uncertainty and growing concern for her well-being, leading her family to report her missing to the Oklahoma City Police Department on February 22, 2020.

The circumstances surrounding Kylie's disappearance are rooted in a personal decision to leave her home. It was discovered that while no one else was present, Kylie had packed all of her clothing and departed. She left behind a note, a brief and poignant message indicating that she was leaving. In the note, she offered a sliver of reassurance, stating that she would keep in touch with her loved ones through social media. This communication, however, did not seem to materialize in a way that alleviated the fears for her safety, and as time stretched on, her case was entered into the National Missing and Unidentified Persons System on March 31, 2020.

Kylie Lehenbauer’s case remains a painful and unresolved story for her family and community. A young woman, on the cusp of adulthood, left her home with her belongings and a promise of contact, but her current whereabouts are unknown. The official investigation, handled by the Oklahoma City Police Department, seeks any information that could lead to answers. The central facts of the case are that Kylie, a 17-year-old, disappeared from Newalla, Oklahoma, on February 11, 2020, after leaving a note explaining her departure. The lack of any confirmed contact or sightings since she left has left a void of information, deepening the mystery and the concern for her welfare.
