What makes determining the time of death a complicated process?

Determining the time of death is complicated because it is influenced by a multitude of factors that can vary greatly in their impact. These factors can include environmental conditions such as temperature, humidity, and exposure to elements, as well as biological factors like the individual's health, the state of decomposition, and the presence of insects. Each of these elements can significantly alter the estimated time of death, making it a multifaceted challenge for forensic scientists. Therefore, assessing the time of death requires a comprehensive understanding of how these various influences interact, contributing to the complexity of the process.
