摘要：Time is one of the most important factors of
consideration in a murder case. It might delicately convict a
murderer, break a alibi, alternately dispose of a suspect. If the
circumstances surrounding death indicate the possibility of
homicide, then both the body and immediate surrounding area
become crucial in estimating time of death. Estimating the time
of death, especially in cases where there are no witnesses, is
critical to the investigation. The governing equation is
governed by the Newton’s law of cooling that provides the time
of death. The Lagrange quadratic interpolation technique is
use to fitting the experimental data so as to gives the accurately
thermal conductivity. The traditional Newton method is also
employed to approximate the solution. The proposed
numerical technique gives good agreement estimating time of
death.
