Algor Mortis

Algor Mortis is the name given to the loss of a body's temperature after death. If the body is found within 24 hours following death it may be possible to use temperature to estimate the time of death provided the following conditions are met:

1. The body has been in a place that has remained at normal room temperature without extreme heat or cold

2. The victim's pre-death temperature was not elevated for example by illness

3. The victim was not wearing clothes that may have insulated the body for example a thermal winter coat

With a normal body temperature of 37° celsius before death, the body cools at a rate of 1-1.5°C per hour. Taking an internal temperature and subtracting it from 37°C provides an estimated time of death. For example, a dead body with a temperature of 34°C would suggest the person died between 3 to 4.5 hours ago.

FORENSIC EVIDENCE

[bibliosauruswrecks]

Okay, forensics side of Tumblr, I have a insomnia-induced and potentially stupid question: How much evidence would someone leave behind if they were to cover their fingers in clear-coat nail polish?

Kevin Keith has been imprisoned since 1994, convicted of opening fire in Bucyrus Estates apartments, Ohio, killing 2 women and a 4-year-old child. At trial, evidence was presented by forensic analyst G. Michele Yezzo. Yezzo testified that the numbers 043 imprinted into the snow along with tyre tracks at the scene of the crime matched the license plate and tyres of Keith’s girlfriend’s car. When questioned about her methods, Yezzo explained that she had matched the tracks not from the car, but simply by consulting a tyre brochure.

Yezzo’s personnel file reveals a long history of questionable methods, with an entry in 1989 stating that ‘she will stretch the truth to satisfy a department’.  A note from just a year before Keith’s trial describes her observational errors as 'failures that could lead to a substantial miscarriage of justice’. Her personal reputation proved just as complex, with co-workers accusing her of using racial slurs and suspicions of a ‘severe mental imbalance’.  

A 7-year-old survivor of the shooting had also excluded Keith’s photo from a line-up of suspects, telling police that her ‘Daddy’s friend Bruce’ was the real perpetrator of the crime. Witnesses placed Keith more than 30 minutes from the scene, while an alternate suspect not only had a license plate containing the numbers 043 but also a brother named Bruce. Despite the absence of any other forensic evidence, Yezzo’s testimony was enough for the jury to find Keith guilty, and he was sentenced to death.

As questions continued to be raised surrounding Keith’s conviction, the governor of Ohio commuted his sentence to life without parole in 2010. Having now been imprisoned for 23 years, an appeals court is currently deciding if he will be granted a new trial.
