Maximum and minimum daily temperatures from an accurate source
Ambient temperature at scene taken at chest level
Maggot mass temperature taken from center of mass
Temperature of ground surface, interface between body and ground, and soil directly under body

2-3 days before the victim's disappearance and 3 to 5 days after the body was discovered
1-2 days before the victim's disappearance and 3 to 5 days after the body was discovered
1-2 weeks before the victim's disappearance and 3 to 5 days after the body was discovered
