Marie Osmond with her son Michael
On February 26, 2010, show business legend Marie Osmond was at the Flamingo Las Vegas, dancing, singing and performing with her older brother Donny as a part of their popular Vegas variety act. After a quick microphone check, Marie was about to run back onto the stage when she got a call from her 18-year-old son, Michael.

"I was just running out as my phone rang, and I couldn't get to it," she says.

Marie finished her performance at the Flamingo, said goodnight to the sold-out crowd and stepped off the stage. Shortly after, she tried to call her son back—but he didn't pick up.

That night, Marie says intuition told her something was wrong.

Asleep in her hotel room after an exhausting day, Marie awoke in the middle of the night to a phone call from the security guard stationed at the gated community where she and her family have a home. He told her people were there to see her. They were from the coroner's office.

"I knew," Marie says. "It was Mike."
