Apple's smartwatch device can record every state of the wearer. One is the heartbeat sensor function, which can record the health status of the user. Unexpectedly, this feature could also help the police arrest the perpetrators. In Australia, Myrna Nilsson, 57, was found dead in his home in Adelaide at the end of 2016. If he is killed, an Apple Watch is tied to his arm. From the data recorded by this smart device, the police arrested the perpetrators of the murder.
Based on this evidence, Caroline Nilsson, the daughter-in-law of Myrna Nilsson, became the only suspect. First, Caroline confessed that her mother-in-law, before she died, came home followed by several men and argued for about 20 minutes in front of the house. Caroline admitted she was tied up in the kitchen and the door was locked.
However, the data on Apple Watch shows that the time taken to kill the victim is about seven minutes. Based on this data Caroline is said to have broken into the house as a perpetrator and killed her father-in-law. According to Carmen Matteo, the prosecutor handling the case, Apple Watch undergoes Myrna, which became important evidence after an analysis of the data was recorded in the device. He said the data were obtained from heart rate sensors tracking the movement and activities of Myrna on the day of his death.
The data shows that victim activity changes at 18:38. At this time it is known that the perpetrator is in the victim's home. "The victim was attacked at 18:38 and declared dead at 18:45," Matteo said.
He added that the analyzed data shows that the victim's heart is still consistent and tends to be safe. But his body was shocked and lost consciousness.
