TAMPA, Fla. – Billy Mays, the burly, bearded television pitchman whose boisterous hawking of products such as Orange Glo and OxiClean made him a pop-culture icon, has died. He was 50.

Tampa police said Mays was found unresponsive by his wife Sunday morning. A fire rescue crew pronounced him dead at 7:45 a.m. It was not immediately clear how he died. He reportedly was hit on the head when an airplane he was on made a rough landing Saturday, and Mays' wife told investigators the TV personality didn't feel well before he went to bed that night.

There were no signs of a break-in at the home, and investigators do not suspect foul play, said Lt. Brian Dugan of the Tampa Police Department, who wouldn't answer any more questions about how Mays' body was found because of the ongoing investigation. The coroner's office expects to have an autopsy done by Monday afternoon.

Mays' wife, Deborah Mays, told investigators that her husband had complained he didn't feel well before he went to bed some time after 10 p.m. Saturday night, Tampa police spokeswoman Laura McElroy said.

"Although Billy lived a public life, we don't anticipate making any public statements over the next couple of days," Deborah Mays said in a statement Sunday. "Our family asks that you respect our privacy during these difficult times."
