An inordinate number of alleged stranger rape cases turn out to be false.
Woman accused of false rape claim 'after fitness watch proved she wasn't dragged from bed'
Jeannine Risley allegedly overturned furniture in the middle of the night to fake signs of a struggle after being told that she was going to be fired.
She claimed she was asleep in a guest annexe of her boss' home when a booted man pulled her out of bed and raped her at knifepoint.
However, police who examined her wrist-worn Fitbit fitness monitor - which includes people's vital signs and data about their movements - said it showed she had been awake and walking around at the time of the alleged attack.
A court in Florida heard how police who rushed to the home in March following a 911 call fund overturned furniture, a knife and a bottle of vodka.
The 43-year-old later told authorities an unknown man had pulled her out of bed at around midnight, attacked her in a bathroom and raped her at knifepoint, according to court documents.
However, police suspected her story did not add up when they failed to find any footprints in the snow around the home or any evidence of an intruder inside.
They discovered Risley's Fitbit - which she claimed she had lost - in a corridor and accessed the data after she agreed to hand over her login details.
It showed that she was awake and walking around at the time she claimed she was sleeping.
Further documents filed with the court reveal that her boss, who has not been named, had told her she was set to lose her role as a temporary director with his company.
Risley, of Saint Petersburg, Florida, has been charged with false reports to law enforcement, false alarms to public safety and tampering with evidence.
She appeared in court with her husband, but spoke only to confirm her name and personal details.
A trial is now set to take place later this year, unless she chooses to enter a plea.
