I get the sense, and this is JMO, that it's been a very delicate tap dance regarding sharing information, for reasons that I cannot even begin to speculate. I don't know if it's simply uniformed, or more trying to answer some things delicately, or in a specific way, or very deliberately, in order to protect the case or the victim. They mostly have tried to stay out of anything of substance and just thank for good thoughts, etc., and repeat over and over that law enforcement wants them to keep sharing her picture. It seems the family is working closely with LE and is likely doing what they instruct regarding this public page. IMO - I have no idea.
The local Denver anchorwoman said they have been trying to report on this case for a week, but were unable to get much information from police until the past few days. They must have their reasons for this.
