Take Kristen DaCosta, for instance.
On probation for earlier crimes, she broke into a house in Somerset, Massachusetts, and stole jewellery.
She was careful to avoid leaving any trace of her presence – she didn’t trash the place, and left everything just as she found it (with the exception of the jewelry)
Nevertheless, the police had no problem identifying her as the thief.
She forgot about . . .the the GPS tracker bracelet fitted to her ankle as a condition of her probation which enabled the police to monitor her movements and registered her presence in the burgled house
Just a suggestion mind, but I think Ms DaCosta should seriously consider a new line of work !
