It is using the value for the last time that you used the key of "killed" (between the keys "changed_names" and "touched_hostage").

I also suggest you follow the advice in Death to Dot Star! and replace a bunch of case of .*? and .+? with things more like [^)]* (unless those delimiter characters are allowed in those places). Your code will be faster, for one thing.
