The estimation of the time of death is significantly influenced by environmental temperature and conditions. This is because the rate of a body's decomposition and the physiological processes that occur after death, such as rigor mortis, livor mortis, and algor mortis, are all affected by temperature and environmental factors. For instance, warmer conditions can accelerate decomposition, while cooler temperatures can slow it down. This can lead to variations in the time of death estimates depending on where a body is found. Understanding these environmental impacts is crucial for forensic scientists in making accurate estimations.

While the other factors, like the type of weapon used or location of the crime scene, may provide useful context or aid in the investigation, they do not directly determine the physiological changes that take place after death. Similarly, witness testimonies are important for timelines or corroborating events but do not provide scientific data necessary to estimate the time of death itself. Thus, environmental conditions are the most pertinent factor when discussing the estimation of the time of death.
