Yes.  When I was in charge of the investigation I know of some screams that I heard, and I went to find out what was all about it, why did the, would someone scream, then I will go and look at what is happening.  Now I would also ask the victim, and ask him who was screaming, what is the problem?  Then if he doesn't tell me what the problem is then obviously I wouldn't know what kind of methods was used.
