I was living in Grand Junction when this case happened. Abby went to the pre-school that my sister-in-law was the director of. I have watched the 48 Hours program twice. There are a lot of things left out of that report. I have no doubt that Michael Blagg is guilty and that Abby is gone, too. My husband is a former investigator (15 years) and when these kind of cases happen we always read between the lines, so to speak.
Jennifer was killed during the night. She was found in her pajama's and still had the retainer in her mouth that she wore at night. She was found in the landfill, surrounded by trash from Michael's place of work. Now what killer would go to the trouble of finding out where the husband worked and put Jennifer's body in the dumpster there? The family van was used to transport her body. It was found back in the garage, keys inside the house. Again, the killer transports the body and then brings the van back to the garage?
A co-worker saw Michael struggling with large boxes being taken to the dumpster and asked if they could help. The answer was a not so nice no. This was earlier in the day before he reported Jennifer and Abby missing.
Nothing was taken/stolen from the house, although Michael did report jewelry stolen. However, it was found hidden several months later in the house.
He stole equipment and furniture from his work place and then gave an interview on camera with those very items front and center. Not to smart, in my opinion.
I know there are more things not mentioned but it is late and I don't want to get it wrong.
