One method would be to use custom identifiers for each:

Code:
alias weapon {
  var %weapons = knife,axe,gun,rope
  var %rand = $rand(1,$numtok(%weapons,44))
  return $gettok(%weapons,%rand,44)
}
alias location {
  var %location = bedroom,dining room,kitchen,study
  var %rand = $rand(1,$numtok(%location,44))
  return $gettok(%location,%rand,44)
}
alias murdertime {
  return $rand(1,12) $+ : $+ $rand(1,60) $+ $iif($rand(1,2) == 1,am,pm)
}


Etc.

Then, when you want to use a piece of data, you just use the identifier. For example:

//echo -a $murdertime
//echo -a $weapon
//echo -a $location

You can, of course, combine these into one //echo -a //msg or whatever.

If you're storing the data for later use, then put it into a variable when you first generate the information:

//set %weapon $weapon

For the victim, witnesses, and killer, I'm sure you probably want to use people in the room. So you'd use $nick($chan,$rand(1,$nick($chan,0))) to get a random person. Then compare that to others so you don't have the same person in 2 different roles.
