Heiress Casey Johnson Found Dead Days After Reported Fight With Lover Tequila

Jan. 5, 2010— -- Casey Johnson, socialite and heiress to the Johnson & Johnson fortune, may have been dead inside her Los Angeles home for days before her body was found Monday.

TMZ quoted law enforcement sources as saying it appeared the 30-year-old had been dead for "several days" and that police had opened a death investigation.

Johnson had recently announced her engagement to reality TV star Tila Tequila. Tequila told TMZ Monday evening that the two had fought last week and that she was unable to reach Johnson Dec. 29 after she left her dogs at Tequila's house. The reality star told TMZ that Johnson's phone had been turned off ever since.

"I can't stop these haunting visions of her and I," Tequila tweeted early this morning. "We made such a lovely couple, only beginning to spend the rest of our lives together..."

Johnson, the daughter of New York Jets owner Woody Johnson, appears to have last tweeted shortly after 1 a.m. Dec. 29.

The Johnson family released a statement, The Associated Press reported, saying it's "mourning its tragic loss, and asks for privacy during this very difficult time."

Police said Monday that Johnson appears to have died of natural causes.

"Our officers conducted a preliminary investigation which appears to be an apparent natural death,'' Los Angeles Police Department spokeswoman Officer Sara Faden said. "There was no evidence of any foul play and the case is now being handled by the coroners, pending a toxicology report.''
