LE's goal is to find Kelsey and apprehend the perpetrator of any crime committed against her. They are not going to release information about an active investigation unless it is helpful in furthering that goal.
For instance, let's say they discover that her debit card was used at a gas station in Colorado Springs on 11/24. Then I would expect to see a request from the WPPD for camera footage in the area, witnesses to come forward who were at that location on that day and time, etc.
Otherwise, there is no reason to share that sort of information with the public. They already have a timeline -it is standard operating procedure - and they continue to investigate and add more information as it is discovered. It is not the public's job to establish a timeline.
