Most likely you are looking for the "True detective" ending. Unlike the "Local hero", it does not start immediately. That means calling the police with window closed and than waiting for the police (comes after 2 visitors). Either that or the game is bugged.

Yes that one, I've tried like 8 times and still got different endings instead of that one so I think the game got bugged, I re-installed it and played it again but still didn't get it, that's very unfortunate because I liked the game and wanted to get all the endings but still thank you for the quick response, I appreciate it.
