Friend of Dennis Prince says Houston had terminal cancer, reports say

Robert Eglet, a Las Vegas trial attorney who was friends with the Prince family, told Fox News Digital that Houston had confided in him about his terminal cancer diagnosis before the shooting.

"Joe told me this not long before the shooting, that he was dying of terminal cancer," Eglet said, according to Fox News. "Makes me wonder if he felt like he had nothing to lose? I really don't know though, I can't make any sense of this all."
