It was an interactive game in the early 00's where you had to solve a serial killing. The game would call you and you could hear people being killed, talk to detectives, or even the killer. It would tell you how many people were still alive. You could get a call 24hrs a day. In the end if you were still alive and could correctly identify the killer you won some prize money or something. I remember playing it, seeing a news piece on it, even a weird recording on my answering machine. Problem is I can't remember the name or find anyone who even remembers hearing/playing this. So thanks in advance for taking your time to help find anything.
