Dan Noyes: "He seemed like a nice guy at first?"
Woman: "Oh yeah, he seemed like a tall, handsome, you know, nice looking, gentle at the beginning."

She says he asked her to marry him after only two months. When she refused, she says Cassidy's personality changed.

Woman: "Yelling, screaming, insulting me, he did a lot of that, I got hurt a lot. I got hurt."
Dan Noyes: "Physically?"
Woman: "Yeah."

In a filing from a domestic violence case in Santa Clara County Family Law Court, the woman claimed Cassidy "exhibited major mood swings as a result of bipolar disorder," adding, "several times during the relationship he became intoxicated, enraged and forced himself on me sexually."

The woman told the I-Team, "He was drinking a lot, he was drunk. At my apartment, he pushed me to bed, forced me to have sex."

It was actually Cassidy who filed for a temporary restraining order against the woman, claiming he broke up with her, she kept coming to his house to the point he had to call the police, and that she may have keyed his car. The woman denied the accusations.

Robert Cummings was her attorney on the case.

"There was a lot if gaslighting that went on, there was a lot of controlling and sexual abuse that you see in these situations," said Cummings.

Cummings said Cassidy acted as his own attorney.

"I feel lucky. I'm still alive, I didn't die, you know."
