csi season 1 episode7 and 8 - fraxing

7: Blood drops
The CSIs arrive at a family residence where four people have been brutally stabbed. Mr. Collins is found in the second floor corridor, Mrs. Collins in her bed, and their two sons in their room.

8: Anonymous
Grissom and Brass are called to a disturbingly familiar crime scene. Stuart Rampler lies dead in a bathtub in an apparent suicide. Grissom finds a tape recorder nearby and plays the suicide message – aside from having been recorded backwards and changing the personal details to reflect Rampler’s name and birthday, the message is identical to the recorded message found at the Royce Harmon murder several months ago. Grissom realizes that the killer has returned.
