Yes--without KEYS. Without KEYS! Meaning she'd have had to leave a door open at home. Leaving a door open, when, according to Geragos, she was so concerned about the homeless people who trooped by on their way from shelter to park, park to shelter... when, according to Scott, he took to parking his truck in the driveway with the front facing outward, b/c he said that way he had less people getting in and rummaging around in the truck's toolbox to steal from him.
Oh, and let's not forget--she would have gone out to walk the dog w/o keys, therefore having left a door open, and also having left the gate to her backyard open, b/c we know Karen Servas found it open. Might as well put out an engraved invitation to thieves: "Please burglarize this house."
Don't forget she left all the diamonds on the dresser with the door unlocked.
And left her shoes in the closet with her coat and purse. And her cell phone was dead in her car.
