A Connecticut man will likely spend much of the rest of his life behind bars for murdering his wife, thanks in part to the wrist pedometer Fitbit she was wearing.

On Thursday, a judge sentenced 40-year-old Richard Dabate to 65 years in prison after he was convicted in May of murdering his wife, 39-year-old Connie Dabate, just days before Christmas in 2015, WTNH-TV reports.

The judge sentenced Dabate to 60 years in prison on the murder charge, with the additional years for evidence tampering and making a false statement to police.

Dabate had pleaded not guilty to the charges and asserted that a masked intruder broke into the couple’s home, murdered his wife and then tied him up.

Dabate himself testified during the trial, as did his mistress, who gave birth to a daughter that he fathered, according to the Hartford Courant.

Prosecutors alleged that Debate, faced with a pregnant paramour who would upend his life, staged the crime scene to look like a home invasion.

The state presented evidence from the wife’s Fitbit that contradicted Dabate’s assertions and indicated that she had been alive and moving for an hour after he claimed she was dead.

Dabate had claimed that Connie was murdered at 9:05 a.m., but the Fitbit data, GPS records and security camera footage showed that she went to the YMCA and did not return to the home until 9:18 a.m.

The Fitbit data then identified indications of casual walking at 9:27 a.m. and did not detect any running. She was last recorded moving at 10:05 a.m., NBC Connecticut reports.

Prosecutors further raised questions about why there was no evidence of forced entry into the residence.

Dabate’s defense team argued that DNA of an unknown man was identified in multiple places throughout the home, including on an upstairs closet door, the family safe and on a gun that was used to murder Connie.
