Where's the Halloween Party?

About 4 years ago this season,after getting mom settled in bed, I went up to watch a movie with Dave. About halfway through, I took a break to get a drink and check on Mom. The front door was cracked and someone was frantically knocking and ringing the doorbell. I reluctantly answered. A neighbor woman was pointing down the street and said they were coming home from a party and Mom was laying in the street. They had already called 911. Mom was in her nightgown, but carrying her day clothes and shoes. She had been 'showing the imaginary people where the party was'. She was bruised and scrapped all down her right side and xrays showed her right cheek to be broken. It was at that time we put guard locks on the inside of all the doors and didn't leave her alone day or night. My self or one of my daughters began sleeping in her room at night. Before that we had a monitor system set up, but she had made no noise at all during her 'escape'.
