I hadn't heard this. Do you happen to have a link or source on it?
I'm surprised because all the TC videos I've seen either used one model tickling another, or in the "bedspread" series where the guy was 'ler, there was always another person continuously panning and tilting the camera. Generally, abusers don't want witnesses, especially when a tripod could have easily been used instead. Also, the tone of the TC videos that I've seen always seemed fun, and none of the models ever seemed even a little bit upset. They also all dutifully ignored the "fourth wall," i.e. they didn't talk to the camera person, nor look into the camera.
Obviously, that doesn't make abuse impossible, as no video will ever show us what happened after the camera's turned off, and he could've also edited out whatever footage, (even though most of the videos seemed continuous and without edits). But I'd be curious to hear what the accusers said. And how he died.
