Casey Johnson, the socialite daughter of New York Jets owner Woody Johnson and heiress to the Johnson & Johnson business empire has died, a spokesman for the family and police said. She was 30.
TMZ.com reported that Johnson was found dead Monday. Police officers responded to her Los Angeles home around 11:51 a.m. where paramedics had already pronounced Johnson dead, officer Sara Faden said.
Los Angeles County coroner spokesman Craig Harvey says an autopsy will be held Tuesday for the 30-year-old Johnson.
Johnson had diabetes, but it was unclear whether that was a factor in her death. Harvey said he could not provide other details and didn't immediately confirm police statements that there were no signs of foul play.
Faden said she did not know how long Johnson may have been dead by the time authorities arrived, but TMZ reported that it could have been "days".
She said Johnson's death may have been from natural causes since a preliminary investigation turned up no signs of foul play. But Faden added that a final cause of death will be determined by coroner's officials, who will seek toxicology tests. Results of those tests could take six weeks to obtain.
In a statement released through publicist Jesse Derris, the Johnson family said it "is mourning its tragic loss, and asks for privacy during this very difficult time."
CBS News correspondent Michelle Gielan reports that Johnson reportedly had problems with drugs and alcohol, and she led an extremely troubled life.
In 2007, reports Gielan, the heiress adopted her now-three-year-old daughter Ava from Kazakhstan, but she lost custody to her mother in 2009 when she was found to be living in squalor.
She gained celebrity as the girlfriend of Tila Tequila, a bisexual reality TV star best known for "A Shot at Love with Tila Tequila," which ran for two seasons on MTV.
Tequila's publicist says the two were engaged.
On her Twitter page, Tequila wrote, "Everyone please pray 4 my Wifey Casey Johnson. She has passed away. Thank u for all ur love and support but I will be offline to be w family."
Johnson, a high school classmate of fellow socialite Paris Hilton, told Vanity Fair in a 2006 interview that her decision to turn down Hilton's invitation to be her co-star on "The Simple Life" was "the stupidest mistake of my life." Hilton eventually chose Nicole Richie. "I kick myself in the butt everyday," she told the magazine.
While Johnson did stand to inherit a sizeable fortune from the family brand, Geilan says there are reports that her father had recently cut her off because she repeatedly failed at rehab.
