Authorities said Dabate told them a masked man had entered their home Dec. 23, 2015, shot his wife and tied him up before he burned the intruder with a torch. But the New York Daily News reported the Connecticut State Police wrote in an arrest warrant that his wife’s Fitbit was logging steps after the time Dabate told them she was killed.

As far as witnesses go, the technologically advanced 21st century is producing some interesting ones.

First, recordings from an Amazon Echo were used in an Arkansas murder case, and now, police in Connecticut have used a woman’s Fitbit data to disprove her husband’s version of events, and subsequently arrest him for her murder.

Fitbit is a wireless-enabled wearable device that measures a person’s fitness metrics, such as number of steps, heart rate, quality of sleep, etc.

In this case, police obtained a search warrant for Connie Dabate’s Fitbit data, which registered movement more than an hour after her husband alleged an intruder shot her.

According to CNN, on Dec. 23, 2015, suspect Richard Dabate returned to his Connecticut home to retrieve his forgotten laptop, at which time his wife was working out at the local YMCA.

Richard alleges he heard a noise upstairs between 8:45 and 9:00 a.m., and when he went to investigate, found a camouflaged intruder. It was at this moment Connie returned home—and the intruder fatally shot her.

Richard alleges the intruder then tied him up and burned him with a blowtorch, until he was able to turn the tables and the burned, spooked intruder ran off. Richard pushed the panic button on the house’s alarm and called 911 at 10:11 a.m.

But, when police arrived, they couldn’t find a suspect in the area. There were no signs of forced entry, and nothing was stolen from the house. K-9s were brought it, but they too could not find any evidence someone else was in the Dabate’s house.

So, police obtained search warrants for Connie’s Fitbit, both the Dabates’ cell phones, computers and the house alarm logs. These revealed a very different story than Richard told investigators.

Namely, Connie’s Fitbit registered movement at 9:23 a.m., the same time the garage door opened into the kitchen, per the timeline of events laid out by CNN. Between that time and 10:05 a.m.—which is when all movement stopped—the Fitbit recorded Connie walking a total distance of 1,217 feet. However, the walk from Connie’s car to the basement, where the intruder allegedly shot her upon entrance, would be no more than 125 feet.

Additionally, Connie was active on Facebook between 9:40 and 9:46 a.m., utilizing the IP address at her home.

All in all, Richard’s story was not holding up—something the police quickly realized. After the discovery of his extramarital affair and impregnation, and his attempt to claim his late wife’s life insurance policy, Richard increasingly became a suspect.

Now, he is being charged with murder, tampering with evidence and providing a false statement to police. He was released on $1 million bond, and is scheduled to appear in court Thursday or Friday of this week. He maintains his innocence.

In this case, it seems police had no problem obtaining Connie’s Fitbit data via a search warrant. However, that’s not always true.

In the Arkansas murder case referenced earlier, Amazon refused to turn over the recordings, filing a motion to dismiss the warrant, citing the First Amendment rights of owners.

“Amazon does not seek to obstruct any lawful investigation, but rather seeks to protect the privacy rights of its customers when the government is seeking their data from Amazon, especially when that data may include expressive content protected by the First Amendment,” Amazon’s lawyers wrote in their motion, obtained by Forbes.

The recordings were eventually submitted as evidence, but only after the suspect willingly volunteered them.

While an Echo can record voices and personal “searches,” a Fitbit can only log specific fitness trackers; thus, the expectation of privacy may be considered less in the case of Fitbit data. As evidenced by the Dabate case, the only real data that can be revealed from the wireless fitness tracker are related to movement.
