What eroge/VN is this picture from?

Sorry if this is the wrong place to ask but does anyone know where this picture is from?

It looks like a game cg from some murder/mystery/thriller VN or something, any ideas?

Edit: After some digging, I think there's a good chance this picture comes from vndb. The image was originally posted on 4chan 5 years ago with no source and it has the same aspect ratio as the images used in vndb for screenshots so there's a good chance it was taken straight from there from a VN's game CG. But there aren't many clues except the game should be dated before 2013 at the very least(judging from the screenshot it should be even earlier like pre 2008-2009). The game genre is also probably related to crime in some ways since it shows a woman getting buried alive. I've searched the whole vndb and acdb for the character but nothing seems to come up so there's a possibility the character hasn't been indexed(or plays a minor role) but that's also the case for many(older) games in vndb, so the best shot is to look for the game name directly(or artist's name if the art style is familiar).
