LOS ANGELES — An autopsy is planned for Casey Johnson, the heiress to the Johnson & Johnson empire and daughter of the owner of the New York Jets who was found dead in her Los Angeles home.

Los Angeles County Chief Coroner Investigator Craig Harvey says the examination will be held Tuesday for the 30-year-old Johnson.

He says he cannot provide other details and didn't immediately confirm police statements there were no signs of foul play.

Paramedics pronounced Johnson dead Monday. She was the daughter of Woody Johnson and the girlfriend of reality TV star Tila Tequila.
