It has been nearly 30 years since college student Catherine Sposito was murdered while on a hike near Prescott, but officials aren't giving up hope that someone will come forward.
Yavapai County Sheriff's Officials are offering $10,000 for any information that leads to arrests of those responsible for her death on June 13, 1987.
On that day, she reportedly rode her bike to the Thumb Butte trailhead and was murdered by at least one person while she was hiking.
Horrifyingly enough, there were other hikers in the area who heard her screams, but they didn't get to her in time.
Yavapai County officials say she had dinner with friends the night before and told them about her plans to hike Thumb Butte.
No suspects were ever identified or located, but detectives are still working to utilize new technology that wasn't available 29 years ago to process evidence.
