Secrets & Flies

Plot:

A woman is found dead on the floor of her house near her baby's cradle. The gun in her hand, as well as a suicide note and a fridge-full of breast milk, suggest that it was a suicide. The lack of blood on her hand, however, indicates that she was murdered. During autopsy, it is revealed that her hymen is still intact; she is still a virgin despite having given birth to a son. Meanwhile, Grissom is called in by Ecklie to refute an experiment involving insects which were used to create a time-line for a murder case.
