They serve to control your physical activity, to tell you if you sleep well, to remind you to stay hydrated and now also to solve murders. Intellectual watches and activity wristbands such as Garmin and Fitbit have already been used in the United States and the United Kingdom to prove the alibi of suspects of different crimes. This is one of the most useful aspects of a technology that keeps us located 24 hours a day.
In March 2018, two people watched Mark Fellows shoot John Kinsella in Manchester (United Kingdom). The police investigation confirmed the testimony of the witnesses and Fellows was arrested and prosecuted. According to several newspapers British, both were in opposing camps and related to the Mafia. Soon it would be discovered that this was not his first murder. This detention reopened the investigation of a crime that took place three years earlier and of which Fellows automatically became a suspect.
The investigators did not have conclusive evidence to prove that Fellows was also guilty of the murder of Paul Massey, which had happened in 2015. Until they realized that the suspect was wearing a Garmin Forerunner watch. The smart watch, usually used by people who love sports In order to obtain information about his physical activity, he had registered all the journeys made by Fellows during the last years.
Thus, the investigators could know that the suspect had been hanging around his victim's house in April 2015, two months before committing the murder. The clock recorded a 35-minute activity that began near his home and continued to a road near the home of Massey, the victim. As he got closer, his speed dropped from 19 kilometers per hour to four, suggesting he got off his bike and started walking. Then he stopped for eight minutes. The authorities used this data as evidence to support the accusation. Mark Fellows has been sentenced to life in prison for the two murders.
- Technology does not deceive
Something similar happened in October last year in California (United States), this time with the Fitbit activity bracelet. The functions of this device are similar to those of Garmin watches: they collect data such as heart rate, calories burned, distance traveled and journeys. The data provided by his GPS were used to charge A. A, suspected of killing his stepdaughter, with murder. In statements to the police, the defendant claimed that he had left his stepdaughter's house 15 minutes after arriving. But the data from his Fitbit were later compared to video footage from a security camera and confirmed that the murder occurred while he was still in the house.
The data found in smart loudspeakers have also been used by the authorities as evidence. In November 2018, a judge in New Hampshire (USA) ordered Amazon to deliver the Alexa recordings, a voice assistant that has recently become popular and interacts with users using a microphone and a loudspeaker. The judge believed that the device, along with information from paired smartphones, could help prove that the alleged killer, D.S. was in the house at the time of the murder.
