The women was holding a gun but there was not blood on her and of where she would have shot herself. They couldn't find a red pen anywhere. They found the pen in the mothers purse.

**2. Explain how Grissom figured out that the blow fly data in Mark Thayer's was incorrect.**
They used the flies cycle to figure out how long the body had been there. They digested a toxin and found out that mailaphyon was sprayed on the pigs skin. With mailaphyon it would be delayed up to four days. The lab tested the flies for toxins. Since the mailaphyon was sprayed it means that the girl wouldn't have died on the 1st but on the 4th.
