Who killed teen horse trainer Rachel Hansen?

On June 4 2022, 19-year-old Rachel Hansen woke up to a stranger in her Gilbert, AZ apartment. The suspect shot her, then left, and Rachel later died at the hospital. The teen had been working for years as a horse trainer and had just moved into that apartment after living on a ranch. Nearly two years later, her murder remains unsolved, but her parents feel two odd circumstances in the days leading up to her death weren’t properly investigated.
