Who caused Rize to die?


In the first episode, someone threw the crane in order to kill Rize, however
that also prompted in having to save Kaneki from totally being devoured/killed
.

That was the point from where everything basically took off.

Was the fall of crane just a coincidence or was it deliberately caused by
someone in an attempt to kill Rize and if so, who could have it been?




In the Manga near the very end Tokyo ghoul, Kaneki remembers the incident, and
it was shown that

> The Ghoul Group called the clowns did it as One of them, Souta, was there.

The specific incident summary on the
[Wiki](http://tokyoghoul.wikia.com/wiki/Steel_Beam_Incident) confirms this.

The reasons why are not clear yet in TG:RE, as there are several groups that
could have been the reason why it happened, or it could have been spur of the
moment.
