I need help finding a few sound effects for my school's drama production...?

We are doing Agatha Christie's And Then There Were None. I need help finding a few sound effects. One is the sound that we are going to be using whenever someone dies... We would like this to be short and dramatic, kinda like the sound from Law and Order but obviously not that sound. The second sound is what we're calling the "sound of tragedy." This is the sound that we are going to be using whenever something dramatic happens like when one of the characters says that their host is a homicidal maniac. We also want this sound to be short and dramatic without being corny... If you could give me the link to an appropriate sound or anyplace where I can download one or both of the sounds for free (and I would reeeally prefer that the sounds are free) then I would greatly appreciate it!! Thanks!
