The Hartford Courant ran a long, detailed account of Connie Dabate's 2015 murder in Ellington, Connecticut titled, "A Marriage Marked By Secrets, A Murder Case Months In The Making."
It's a sad, complicated tale of domestic violence and murder, cheating and lying, but it's especially notable for the way police have brought charges against Connie Dabate's husband, Richard Dabate. According to KFOR.com, his arrest warrants cites his wife's Fitbit records.
Richard Dabate's story of a masked intruder who shot his wife and fled his home reportedly began to unravel in no small part due to movements captured by his wife's Fitbit. From The Hartford Courant:
Those records showed that her last movements inside the Birchview Road home were at 10:05 — nearly an hour after Richard Dabate told detectives she had been killed by the masked intruder. She was wearing the Fitbit because she had gone to a YMCA fitness class.
