Apple's controversial AirTags were used by a woman in the US to track her boyfriend to a pub before she killed him, according to an affidavit.
Gaylyn Morris has now been charged with murder in Marion Superior Court in Indiana after she attacked Andre Smith and ran him over outside Tilly's Pub in Indianapolis earlier this month.
The GPS tracker, along with similar offerings from Tile, Samsung and more, are small devices designed to be attached to commonly lost things to make them easy to find, like keys.
But there are increasing concerns that the devices are being used to track people and vehicles without their knowledge.
Earlier this week it was reported a policeman in the US had been suspended and charged after using an AirTag to stalk and terrify his ex-girlfriend.
Apple has increased the security of the devices, including making warning tones louder and sending notifications that alert people when an AirTag unlinked to their account is near, but that didn't stop Morris.
Most other brands don't offer that level of security, but the AirTags continue to be popular for such illicit uses.
According to the affidavit, first spotted by website The Register, police were dispatched to the pub in the early hours of Friday, June 3. When they arrived they found Smith under the front end of Morris' Chevrolet Impala.
Morris had asked someone if Smith, identifiable by his dreadlocks, was inside the pub, saying she had a GPS tracker that showed he was there. When she went inside, she saw he was accompanied by another woman, who Morris immediately got into an altercation with.
One witness said Morris had stated "she had air-tagged and GPS followed Andre Smith, and that he had been cheating on her".
Morris then swung a beer bottle at the woman, but Smith grabbed it and blocked her. All three were then asked to leave the pub by the owner.
A witness then looked out the window and saw Morris driving a car, "and she pulled forward and clipped Smith, and he went down under the car, at which time, Morris backed over Smith then pulled forward and hit him for a third time", the affidavit stated.
Another witness said Morris sped around them to run Smith over.
"When she hit him with the car, it dragged Smith to where he was when officers arrived. [The witness] stated that Smith's legs were still in front of the passenger front tyre with his body completely under the car, and his head had been completely run over by the driver's side tyre."
A nurse tried to help Smith who was still alive, but his breathing was shallow and intermittent. He then stopped breathing, but the nurse was unable to perform CPR as "Smith’s body was completely under the car between the front wheels with his head on the driver's side behind the front wheel and his feet were at the passenger side front wheel".
An Apple AirTag packaging box was then found in a search of Morris's car and she was carrying an iPhone when arrested.
According to The Register, Smith's aunt Reneka Day said: "Those tracking devices should not be used by the public. They should not be available to the public. They should only be used for hospitals and law."
