I only remember this particular scene…

A Group of friend or I don’t really know if they’re friends. Are arguing with this woman (who might be cursed or might be a witch.. honestly IDK) while they’re in what looks like warehouse. She is yelling at the group, with a video camera in her hands filming the whole thing, she is laughing hysterically and just has a look of evil, she walking up the mental stairs and starts putting a noose around her neck . She finally says something to the group and jumps, obviously killing herself. In the another scenes the group is seen talking to the cops because they are being investigated for her murder in which the tape that she recorded somehow gets messed with and show the group arguing with her and pushing her off the stairs to her death. One of the memebers in the group says” this is not the tape ! Who gave you this tape ! This is not what happened! Someone messed with this tape ” and I guess they get sent to jail for ” murdering her” .

But that’s not what happened.

If someone can please help me with the name of this movie !
