My 757th possible scenario about the machinery running at midnight or thereabouts. HYPOTHETICAL: SM was murdered at home. BM leaves her body at the house, drives to Salida, and digs up enough dirt to load into the back of the pickup to cover a body. He has to then re-level and re-tamp the dirt for the concrete pour the next day. He heads back to the house, cleans up, then loads the body under the dirt in the back of his truck. He either starts out for Denver and leaves the body somewhere on his way to Denver or he dropped the body somewhere nearer Salida. I mentioned in an earlier post that the area between Johnson Village and Antero Junction was the least populated most rugged area between Salida and Denver. Johnson Village is about a 40 minute drive from the Morphew home.
If he is stopped on his way to Denver, he is just a landscaper on his way to a job in Denver,. No suspicions would have been raised because no one knew that SM was missing at that point.
When LE learned about the machinery running at night, that BM had been hired to do the prep for the concrete pour and that his truck was there that night, they began to investigate the site with GPR and dogs. The GPR would have found spots that indicated ground disturbance. This all together was likely enough PC for the search warrant. It would also account for the fact that they might not have found anything during that search. (Although we still don’t know if they found anything or not.)
