Five years ago, a 38-year-old woman and her 45-year-old husband lived with their three children, aged four to nine.
They hired a 22-year-old nanny recommended by others, who was taking a break from school. She was praised for her childcare skills by family friends.
The nanny quickly became part of the family, accompanying them on trips and caring for the kids during weekends and sometimes on weekdays.
While the mother appreciated her care, she started noticing suspicious behavior.
Wanting to confirm her suspicions, the woman installed hidden cameras.
