A team of researchers from the team of Santiago de Compostela has discovered an interesting new way to establish Time Of Death. Their discovery is based on the analysis of several substances from the vitreous humour of the eye (which is the gelatinous liquid that is found behind the lens of the eye), and they have developed a piece of software that does the analysis, which makes it possible to establish precisely the time of death. The information will make the work of the police and the courts a lot easier.
To apply this technique, the researchers analyze potassium, urea and hypoxantine (a DNA metabolite) concentrations present in the vitreous humour of the eye of the human cadaver, and introduce these figures into a computer program. The software uses this information and is capable of establishing the time at which death occurred.

Three aspects of this review that were well presented were what was developed, what it does, and how it will affect forensic science. Two ways in which the review could have been better would be to give examples of cases where this oculd help, and how the information gathered from the vitreous humour is converted into calculations of time of death. One thing that surprised me about this review was that DNA in the eye could be used to help determine ToD.
