Things are rather quiet, are they not?

For a moment, maybe you think that nothing's happened overnight and maybe that nobody will turn up dead-- that is, until you enter the ballroom to find a sight unlike the previous two discovered bodies.

You'll find that the ballroom is a mess, and that two large vines rest on the floor below you, with a trail of blood leading up to Cagney's body. Cagney's body lay in the middle of the ballroom, his eyes wide in fear and anger, with a single bullet wound through his neck. The blood splatters that surround his head, however, are in the shape of flower petals--

and the blood splatters that lay below his dismembered arms seem to have blood forming the shape of petals.

A few feet away from Cagney's body lay a camcorder.

Who does it belong to? Why is that there?
