Doctors raise doubts over suicide verdictsExperts warn of flaws in postmortem blood testsFriday September 17, 2004
The GuardianMiscarriages of justice are "almost certainly" taking place because of a mistaken belief that it is possible to calculate from blood analysis at a postmortem examination how many tablets somebody swallowed before they died, a group of eminent scientists and doctors says today.
Their editorial in the British Medical Journal was written after the death of the Iraq arms expert David Kelly and the Hutton inquiry which concluded that Dr Kelly killed himself by cutting his wrists and taking painkillers.

Blood that is not circulating after death is not the same as before death, said Robert Forrest, professor of forensic toxicology at Sheffield University and one of the authors. "After death, drugs which are bound in tissue move back into blood."
The authors write in the BMJ that drug concentrations are likely to have changed before blood samples can be taken. "For many drugs, including those found in David Kelly, concentrations may increase by as much as 10-fold," they say.
