So there was a movie.
I watched it few years ago, can't find it again :(
The movie started as crime scene investigation at apartment building (multi-storey house?).
main character: policeman
main suspect: husband
SPOILER START (highlight):
Woman was murdered at her own flat. There was only blood, no body.
No real good suspect. Apart from her own husband.
Everything was pointing too clearly at husband so police were trying to find another way to find who was responsible for it.
There was beautiful plot twist at the end when at court...
attorney suddenly said that they found her! The woman suspected to be dead and pointed at the main door.
Everyone looked at the door. Everyone... except from the husband...
Then at the very end he tried to kill himself jumping though balcony at his apartment when brought there by the police.
SPILER END
