The criminalist did not take pictures of the stain prior to cutting out and testing it.
There is no way for the criminialists to determine how long that may have been there.
The MH floor had 19 stains...1 tested as positive for blood....it was approximately 1/4"...no picture was taken prior to testing and cutting out.
The dogs did not hit on the MH and there is no way for them to determine how long it was there....MH had been in neighborhood since 11/00...unlocked.
In case no one else has already responded to this (I tend to work behind you faster typers):
I believe the MH was normally kept at a storage facility 30 miles away. It was only at the house during the times when DW was loading, unloading, or cleaning it, or on the days around those times.
When it was at the house, it was normally locked.
Still, DW's ownership of the MH overlapped by around two years with his proximity with the vD family. So, it could be that the kids got in at some point there.
It could also be that the forensic evidence got into the MH in some other way. For example, if DW and Brenda had "played" in there. Or, if the SDPD planted it. (Why didn't they find the hand-print the first time they looked?)
Cordially,
