'Timestamps' on the Wrist

Determining the time of death for victims of unnatural deaths is making groundbreaking progress through wearable devices like smartwatches. As cases increase where the time-of-death puzzle—the most fundamental yet decisive information in uncovering the truth of an incident—is being solved through everyday digital devices, the paradigm of investigations is shifting.

Smartwatches record users' heart rate, activity levels, sleep patterns, and more in real-time. This biometric information is stored in the cloud and includes precise timestamps. By analyzing a deceased person's smartwatch data, investigators can estimate the time of death through the last cardiac activity, cessation of movement, and other indicators.

New Evidence for Investigations

Traditional time-of-death determination relied on autopsy findings such as body rigidity, rigor mortis, and body temperature. However, these methods have significant margins of error depending on environmental factors. In contrast, smartwatches—as devices typically worn by victims in daily life—provide objective and accurate time information.

Investigative authorities now make securing data from victims' smartwatches, smart bands, and fitness tracking devices a standard procedure when investigating unnatural death cases. This is because access to cloud accounts allows them to understand lifestyle patterns before and after the incident.
