Oh how I love it. The Chicago Tribune had a tidbit on the various technology devices in his home outing a murderer to the police.
The tale involves one Richard Dabate was found on the floor in his kitchen after a 'desperate' 911 call moments previously. He was bleeding and tied to a chair claiming "They're still in the house".
It seems he had killed his wife, Connie and there were no perps to be found and no witnesses. This lead detectives working the case to evaluate all the personal electronics all over his house.
Her fitbit told a good piece of the actual tale with the home alarm system, facebook, and a key fob filling in the blanks of that actual account which rendered his version totally false.
The data essentially caused him to be charged with his wife's murder to which he has plead not guilty.
This case has shown the authorities (and me) how the internet of things (connected smart devices with data collection, home assistant devices, trackers, thermostats, televisions, and such) are causing the evolution of crime scene investigation and therefore criminal justice.
This case has alarmed privacy advocates all over and I personally am going around disabling wifi on a bunch of stuff I have laying around. Despite these antics it is said that the internet of things will likely increase from 8.4 billion now to about 3 per person by 2020.
The moral of the story is that if you concoct the perfect back story for committing murder your smart devices may rat you out. Betrayal by possessions. It's the new admissible evidence.
