If you check the blog entry for 3/27/13 you'll see that the 7/3/13 CSI: Crime Scene Investigation episode titled "Fallen Angels" is a second repeat airing. Unlike CBS, I will try not to repeat myself in this current blog.
The body of the Reverend and the man who jumped out the window both had their liver temperatures taken to help to establish the time of death. The internal body temperature is supposed to drop so many degrees per hour after death. This, of course, can vary with environmental conditions and where the body is located. The time of death is only an estimate at best and is really given as a 'window' and range of a possible time of death.
I noticed that Nick wore his gloves when walking to check to find the potential location of the cartridge case. If you watch enough episodes you will notice that the technicians wear their gloves to answer their phones and perform menial tasks after and between evidence collection and handling. This in essence defeats the purpose of using gloves to begin with. It is recommended in crime scenes or laboratory work that the investigator or scientist change their gloves between each item of evidence collected or handled and they certainly should NEVER keep them on when walking out of the scene or away from a completed task.
I was also amazed that the batteries in the buried boys' key fob were still viable after a year underground. Even if they were the super duper EverReady kind, could you really hear the beep under a significant depth of packed down dirt?
I do want to end the blog tonight the way I did in March - mentioning the blood. They stated that the blood on the flashlight was black and not tacky. There is no way to 'age' the deposit of blood but these are indicators of aging. But like so much else in Forensics, the environmental conditions and the surface on which you find the blood could definitely affect these indicators.
As always, it pays to be conservative and cautious.
