Easy to get shoes cheap at a number of places (Dollar store, salvation army thrift store, etc.)
So, here is scenario from the defense, as it appears to be at this time:
2 different men entered the house, without needing to break in, or they were professionals who could break in without leaving any trace.
They snuck into the house making no noise and then surprised her to the extent that she was not able to call 911.
Neither of them sexually assaulted MY, whom they came upon when they got up to her bedroom.
Rather than making quick work with a gun or knife, one or both of them tried to strangle her to death. One or both of them then beat MY to death.
They wore different sized shoes and both walked in the blood and made tracks.
They left no fingerprints or almost no prints inside the home. A possible exception is that one of them was interested in a shoe shine box in the closet.
They each took one drawer from the jewelry box, but left many other valuables including her purse, which was in plain sight and which they probably had to walk by twice (both coming and going from the home.)
They either did not wake up the child while delivering "at least 30 blows" to a likely screaming woman, or they decided, after brutally beating a young pregnant woman to death, not to kill a child who did wake up and might have seen then.
Either MY gave her own toddler adult cold medicine laced with a controlled substance (one which is known to induce sleepiness), or one of the two men gave her some.
After tracking blood around the bedroom, they managed to leave the house without tracking further blood down the hallway or stairs.
Either before or after the murder, they both had a smoke and left their butts behind.
Meanwhile, someone besides the defendant randomly propped open a door, unplugged a camera, and then later moved the same camera in Virginia. Either that or several people at the Hampton Inn conspired to make false reports to LE. The store clerk who gave an eye-witness account of JY buying gas, positively identifying both him and his vehicle, was mistaken and confused.
Did I get it all? What am I missing? I'm sure we'll find out more.
