=Secrets & Flies:=

In one part of the episode, a mother was found shot in her home by her sister who came into town to visit. She had a baby in a pen next to her. There was a suicide note, but it was forged, and also the gun had blood on it that wasn't the victim's. After more research and speaking to Christina's ex-boyfriend, the investigators discovered that her baby's DNA didn't match hers nor Evan's. Investigators analyzed her suicide note, and noticed that it was written under duress. Also, they found the names of the biological parents. On the biological mother's blouse, the investigators found gunshot residue. They then figured out that the blouse belonged to the biological mother's mother. In her purse, they found a red coda pen, the same as the one that was used to write the suicide note. The woman confessed. In the second part of the episode, there is a court case in which Grissom is asked to testify against one of his old colleagues. He is asked to disprove Thayer's theory that blow flies turn to pupa in 11 days, rather than 15. If he is unable to nullify the testimony, then the defendants will be able to prove that their client was out of town on the day of a woman's murder, though there is ample evidence that he was the killer. They found a chemical on the pig's skin that delayed the time it took for pupa to appear. Thayer was arrested for perjury and taken to jail. Grissom found evidence to disprove the theory, thus proving that the man was in town when the murder occurred.

Why did the fly fly? Because the spider spied her.

Answer the following questions:

1. Describe how the CSI team knew that the suicide note was forged. In the pen, the flow of the ink was disturbed, proving that Christina wrote the note when stressed.

2. Explain how Grissom figured out that the blow fly data in Mark Thayer's was incorrect. He did tests in the lab on the same flies that were used in the experiment, and found that there were chemicals that caused a delay in the life cycle of the blow flies that accounted for the delay in time it took for the pupa to appear.
