Autopsy results on infomercial king Billy Mays show he most likely died from a heart attack.

Mays' wife found him dead in his Tampa home on Sunday morning. He was 50 years old.

The medical examiner says Mays suffered from heart disease.

But some people questioned if an emergency plane landing played a role.

One day before he died, May's hit his head during a rough landing at the Tampa Airport.

"All of a sudden as we hit, you know it was just the hardest hit. All the top, you know, the things from the ceiling started dropping and uh, it hit me on the head but I got a hard head," Mays said about the incident.

The medical examiner says there are no signs Mays suffered head trauma, but they will perform more tests.
