Secrets+and+Flies+KS

1. Describe how the CSI team knew that the suicide note was forged.

"Joey is better off without me." Can't find a red pen anywhere in the house, and that was the color used on the note. Signature is Christina's, but the note was written under duress. If you find the pen, you can match the flow of the ink to the note. Red pen found in the purse of the baby's biological grandmother.

2. Explain how Grissom figured out that the blow fly data in Mark Thayer's was incorrect.

Thayer claims that the insects on the body prove that the suspect was out of town at the time of the murder. Grissum's experiments show that flies develop in 11 days, but the tape looks completely valid, and shows that they developed in 15 days.

Grissum looks for errors in Mark Thayer's video and experiment. Fly larvae digested malathione that was sprayed onto the pigs skin. This delays the amount of time that it takes for the flies to lay eggs up to four days. Therefore the experiment that Thayer conducted was staged, and he will be charged with obstruction of justice.
