finding a killer

i was watching this police guy find some killer. he had a walkie talkie that the killer could talk to him on for some reason. and there was this kid that the police guy was talking to and like letting him help out. then the kid went to the bathroom or smth and the killer started talking to the police guy. n i was like well clearly that kid is the killer haha. then i was watching the police guy chase some ppl and they ended up crawling up some weird stairs. then i was in a puzzle room with a moving library and barry got mad at me
