Remote control front door, maybe.
Nancypants might have gone to her safe room and opened it remotely.
The security company could have remotely opened it.
Somehow I do not think this is not as salacious as the media makes it out to be, especially cause he was looking for Nancy.
The only time I ever had a drug tweaker knock on my door was at like 4:30-5 in the morning just sunrise, he held out his ID in front of him with both hands and said please sir, please, call 911 my heart feels like it is going to explode.
I was happy to help him.
he did not have a hammer, or I would have totally banned him
