A WOMAN who claimed she was raped by a stranger when sleeping at her boss’s house has been caught fibbing by her own FitBit.

Jeannine Risley, 43, has been criminally charged after she told police she was sexually assaulted at knifepoint by an intruder while she was staying at her employer’s home in Lancaster, Pennsylvania, in March.

In her horrific account, ABC News reports she said she was dragged from her bed at midnight and raped in the bathroom by a man who was wearing boots.

But her own fitness watch got the better of her.

Officers who embarked on the manhunt detected holes in Risley’s story when they found no footsteps in the snow surrounding the house, and no signs of an intruder indoors.

Detectives steered their investigation towards Risley and discovered tracking data on her FitBit — which she initially said was lost in the attack — revealed she had been walking around during the time she said she was sleeping.

Things got murkier when police uncovered that her boss had recently told her she would no longer be a temporary director with the company.

The criminal complaint states Risley was directed to inform staff of the change during the week of the reported rape, but she had not yet done so.

She has been charged with false reports to law enforcement, false alarms to public safety, and tampering with evidence for allegedly overturning furniture and placing a knife to make it appear she had been raped by an intruder.
