I wonder if MM somehow hacked into one of their devices to obtain the door code or was spying on them using some sort of spyware installed or placed a hidden camera inside a piece of home decor disguised as a gift from one of his former patients and delivered to their door and placed in the home to gain access. I know this sounds extremely far-fetched, but similar if not more extreme tactics have been used by stalkers in the past to stalk their victims through surveillance. And IMHO, MM has been obsessively stalking Monique and Spencer for awhile now.
