C.S.I. '' Viva Las Vegas '' episode 501

C.S.I. Crime scene investigation was a television program about crime scene investigation. The story takes place in Las Vegas, Nevada. I chose this series because it seemed interesting. I think I am going to improve my English skills so I can understand more easily TV news and newspapers.
The characters of the series are Gil Grissom the supervisor of the unit and he is about 50 years old, Catherine Willows is a blood specialist and she is 40 years old, Warrick Brown is the specialist of audio visual, and he is about 35 years old, Nick Stokes is the hair and fiber analysis specialist and he is about 35 years old and Sara Sidle is the specialist of materials and element analysis and she is about 35 years old. The major conflict of the story involves 5 murders around the Las Vegas area.
