"Estimation of the Time Since Death remains the foremost authoritative book on scientifically calculating the estimated time of death postmortem. Building on the success of previous editions which covered the early postmortem period and the third editions coverage of the later postmortem period, this edition includes a new chapter on DNA/RNA degradation and a new chapter on drug testing in hair, widening the scope of the material. Chapters have been improved, updated and expanded, and it includes new and additional images to enhance the text. A unique work of synthesis combining rigorous science with practical guidance, this update reinforces the books reputation as an invaluable resource - and also the standard - for the estimation of the time since death"--.
