'Control Freak'Have You Ever Felt Uncomfortable or Frightened Around a Co-Worker?

Raymon is spending his first full day in a high-security prison, refusing to talk to cops about the crime for which he stands accused: the killing of Yale grad student Annie Le. But a picture of Clark is emerging as an overbearing "control freak" who was upset with Le's handling of the mice in the lab where they both worked.
Clark's co-workers at a Yale University laboratory told police that Clark would have confrontations with scientists and viewed the lab as his territory, a source told The Associated Press, leading police to question if a workplace fight led to Le's death.

Le, 24, was found dead in the wall of a Yale University building where both she and Clark worked. Police found the body Sunday, the day she was supposed to get married. The Connecticut medical examiner said the cause of death was strangulation.
