They’re an unlikely couple, but a billionaire entrepreneur who fell in love with a man on trial for murder are now telling their story. Lauren Jenai is a mother of four and the multi-billionaire co-founder of the popular CrossFit gym empire. Her prince charming is Ty Tucker, who is facing trial for first degree murder. “I know him. He's not somebody who would do that kind of thing,” she told Inside Edition. The pair first met when they were teenagers in Philadelphia more than 30 years ago.
