Mr. G was a big lab mix. This is an easy one to me.....JY was able to get in the house without arousing Mr. G and causing him to bark. Our little dogs bark at everything yet know both of our cars by sound, even before they come in our driveway. They NEVER bark at our cars/arrival.....but only OUR cars. Other close family, they always bark. This is why I believe Mr G never once barked and Michelle never woke up.
JY came quietly in the house, shut Mr G up in the downstairs bath or laundry room, went upstairs, slaughtered his wife, dealt with Cassidy, who BTW I believe he thought would stay asleep through her Mommy's murder. I think Cassidy woke up, JY gave her his Co's cough syrup, put her to bed, and finished off Michelle. As far as scratches, if he wore gloves, long sleeves, and surprise attacked her with a few punches to the face, even if poor Michelle did fight him, his hands and arms would be covered. The shirt had cuffs which would have hugged his arm. There didn't have to be a space between the gloves and shirt.....hence no scratches.
I wear leather work gloves and shirts such as this when working in my rose garden.....I NEVER have a scratch, never.
I believe when JY left, after he used the hose out back to wash away any blood and changed clothes, he let Mr G out and headed back to Va......oh and dropping off his clothes, shoes, gloves, weapon somewhere along a mountain trail never to be seen again. I believe the hose was left running to wash away any evidence of blood. Someone mentioned him using the hose after mowing the grass....the kitchen/laundry/garage is just as easy to get to as the hose. We work in our yard and get dirty, but have never used a hose outside, never.....I don't know anyone who does. We come inside and use the sink in our garage or mudroom.
I also want to mention the lights JY turned.....the manager said in ALL his years of working there, he had NEVER had this happen to the lights. Another coincidence? NO indeed, just more circumstantial evidence.
