Heiress & Fiance to Tila Tequila, Casey Johnson Dies at Age 30 [FOUND AFTER DAYS!]

UPDATES: There are reports that Casey Johnson previously fell into a diabetic coma twice and had to be hospitalized, law enforcement sources tell TMZ.

We're told Johnson had a history of diabetes and insulin syringes were found in her home after she died.

Johnson was taken at least once to Cedars-Sinai Medical Center in Los Angeles. We do not know specific dates of hospitalization, but we're told at least one incident occurred in the last year.

Johnson & Johnson heiress Casey Johnson, who had recently announced her engagement to reality star Tila Tequila, has died at age 30.

A law enforcement source tells TMZ it appears Johnson had been dead for several days before her body was discovered. The LAPD has opened a death investigation.

Earlier today, Los Angeles police confirmed that it appears to be a natural death and there is no evidence of foul play. Before that, her death was announced by Tequila on her Twitter page.

Police Officer Sara Faden said, “Earlier today at about 11:51 this morning, our Wilshire area patrol officers responded to an ambulance death investigation in the 900 block of North Orlando Avenue. The LA fire department also responded and pronounced Miss Casey Johnson dead at the scene."

The Police Officer said, " Los Angeles coroners office will conduct their own investigation, which includes a toxicology screening. There is no evidence at this time that there was any foul play.”

Tila Tequila had announced her death news to 227000 followers by tweeting on her Twitter page, "Everyone, please pray 4 my Wife Casey Johnson. She has passed away. Thank u for all ur love and support but I will be offline to be w/ family."

Casey Johnson was the great-great granddaughter of the founder of the pharmaceutical giant, and the daughter of New York Jets owner Robert Wood Johnson.

Recently, Casey Johnson's ex, Jasmine Lennard, accused the heiress of breaking, entering, and committing sexy crimes in her home.

She found out because Casey's "lesbian Don Juan" girlfriend Courtenay Semel noticed that Casey was wearing Jasmine's panties and recommended calling the cops.

Jasmine hit Casey in where it hurts, her money, which her mother has allegedly cut off until Casey goes to rehab:

"Her house on Mulholland Drive is a mess. The electricity is off, there are rats, the pool is green. She was supposed to be evicted and her Porsche is being repossessed."
"I had been caring for Ava for several months. Casey fired her nanny, then realized it was Nicky Hilton's birthday party and had nobody to look after her. She asked if I could have Ava for the night, then didn't come back for 10 days."

"Basically, she got bored of buying herself bags and shoes and bought herself a daughter from Kazakhstan in 2007, but was too crazy to look after her."

The Johnson clan had no official comment, though one "family source" cited "medical and psychological issues."

And if that wasn't enough for ya, in related news, Tila Tequila is rumored to be pregnant? That rumor is from Tila herself! After announcing her and Casey's engagement, Tila had a few words for her Twitter army:

"Im [sic] pregnant," she Tweeted.

"I am going to become a SURROGATE MOTHER for my brother and his Wife!!...That is my xmas present to them," she continued.

This story will most likey be developing a whole lot! What a young girl...

Just as I said with the Brittany Murphy case, her eyes do seem pretty wide eyed in the recent photos but she could just be thrilled to be engaged. I'll leave that up to you to have your own opinions.

I have already sent a personal email to Tila and would also like to send my condolences to the family of Casey Johnson. May she rest in peace.
