Wow! I was thinking the sameness that they had some sort of evidence to call in the homicide, but one of the news reports said that it is common in that they can get help from other agencies if homicide is call in.
But the blood changes everything, depending on the amount. I'm sure there is blood in my house from me, if someone looks hard enough.
So, regarding the back wall... it is possible that he did- however, on the other side (as seen in the google maps pictures) is a cement lot, with a somewhat flimsy chain like fence around it. 0pretty sure he did go over, I couldn't imagine it would hold his weight, but heprobably didn't go under either.
I am very familiar with the area, even have driven by a few times the past few days.
It was mentioned that there wasn't a wash or river or lake near, but there is. And it empties into a fairly large, usually dry river bed. There are homeless encampments all up and down walking distance, (less than 1/2-1 mile)
I think the oddest part is the vehicle pulling up backwards into the drive way.
