Yes, this is borderline the plot of an early Simpsons episode, but this actually happened.

4-year-old Abby helped local police in Ferndale, Washington foil a staged robbery carried out by her babysitter, the babysitter's boyfriend and another man this week after the trio underestimated her and tried to blame it on a neighbour. According to the police, the babysitter said two armed black men broke into the house, saying that one looked like the man next door which sent the police his way, but when Abby spoke up and said that the burglars were white and not black, the babysitter's story started to fall apart and she eventually broke and admitted to the crime.

We can't be the only ones who think this kid is totally a Matilda, right?
