From the AA, pg 5:
At 9:37 PM, CCSO Commander Avila brought Barry into the house and advised Deputy Brown that they were looking for a piece of clothing from the residence for the search dogs to locate Suzanne. Barry walked to the master bedroom and pointed to the clothing on the floor in the closet. Deputy Brown observed mountain bike gloves and padded shorts in the pile; Commander Avila took a pair of the shorts. Deputy Brown was walking in the driveway when Deputy Defurio told him that there were barefoot marks inside of the bucket on the Bobcat. Deputy Brown went with him to examine and found that the cutting blade on the bucket of the Bobcat appeared to be newly replaced, along with the nuts and bolts.
At this time, the multi-day preliminary hearing concluded, and the entire AA released, IMO, it doesn't follow that evidence as unique as a barefoot mark would not have been thoroughly examined or tested for touch DNA, yet there's no evidence these "marks" were ever explored, period.
Seriously, it truly makes no sense that investigators would have passed on the opportunity to identify BM, SM, or an unknown individual's DNA found inside the bobcat bucket!
However, given the complete context of the AA's barefoot reference on pg 5, and knowledge that the bucket blade was in fact replaced at DSi on May 9, I really think this reference was most likely intended to read as "boot" or "shoe" footprint marks, and that "barefoot marks inside the bucket on the Bobcat" was a simple typing error.
Furthermore, from the previous YT posts demonstrating a blade change on a skid steer/Bobcat -- shoe/boot marks inside the bucket would not be unexpected if not typical. MOO
