Calculations are carried out by a formula Brown & Marshall in modification C. Henssge (Henssge, C., and B. Madea. Estimation of the time since death in the early post-mortem period. Forensic science international 144.2 (2004): 167-175.).

 

Ambient temperature up to 23C°.

(Trectum - Tambient) / (37.2 - Tambient) = 1.25 eB×t - 0.25 e5×B×t

  • t - post-mortem interval (h);
  • Trectum - rectal temperature (C°);
  • Tambient - ambient temperature (C°);

 

Ambient temperature above 23C°.

(Trectum - Tambient) / (37.2 - Tambient) = 1.11 eB×t - 0.11 e10×B×t

  • t - post-mortem interval (h);
  • Trectum - rectal temperature (C°);
  • Tambient - ambient temperature (C°);

 

B = 1.2815*((k×M)-0.625) + 0.0284,

 

  • k - correction factor for cooling conditions deviating from standard;
  • M - body weight (kg).

 

Where the Henssge method must not be used:

  • - strong radiation (sun, heater, cooling system);
  • - repeated extensive climatic changes;
  • - uncertain severe changes of the cooling conditions during the period between the time of death and examination;
  • - the place where the body was found is not the same as the place of death;
  • - suspicion of general hypothermia.
