Norwegian researchers have created a groundbreaking tool known as the "Death Time Detector," which significantly improves the accuracy of determining time of death. According to reports from Norwegian media on July 28, Professor Kjetil Rognum from the University of Oslo developed this innovative device, offering forensic experts a more reliable method for estimating when a person passed away.
Traditionally, forensic pathologists rely on factors such as body temperature and physical changes in the corpse to estimate the time of death. However, the new technology uses a different approach by analyzing a specific substance found in the fluid inside the eye. This method provides a more precise estimation, reducing the margin of error significantly.
According to Rognum, the conventional method can have an error margin of up to 1.5 hours, especially within the first four hours after death. In contrast, the new device narrows this margin to less than 30 minutes, making it much more accurate. Moreover, the detection window for this method extends up to four days after death, which is far longer than what traditional techniques can achieve.
This advancement could have major implications for criminal investigations, helping to provide more accurate timelines in cases where the time of death is critical. The development was highlighted by the Shanghai Medical Device Industry Association, emphasizing its potential impact on forensic science worldwide.
