Abstract: Alcohol and n-butanol appear in large quantity in blood and organs of a drowned animal or person. Experiment of laboratory animals was proved the existence of a high positive correlation between quantity of alcohol and n-butanol in tissues and the time since drowned death within & days. As a result, the linear regressive equations of alcohol in blood, lung and liver and time of death submerged in water were respectively as follows: Y1=- 16. 82 + 12. 95X,Y2=- 58. 53+ 19. 23X, Y3=- 34. 91 + 47. 29X. The regressive formulas of n-butanol in bind, inns and liver and time of drowned death were respectively aS follows: Y4=- 10. 13+ 5. 86X, Y5=- 29. 15 + 16. 17X,Y6 = 3. 75 + 1 4. 3 1 X. Combining the analysis of quantity of alcohol and n- butanol will become a possible new indiCator of drowned postmortem interval.
