Casey Johnson, great-granddaughter of the founder of the Johnson & Johnson company and daughter of Jets football team owner Woody Johnson, was found dead in her home yesterday but investigators reportedly believe that she may have been dead for some time. Johnson suffered from diabetes from childhood and reportedly had a history of diabetic coma, tho at this point it is not known what caused her death. Johnson made tabloid headlines recently when she announced that she was engaged to Tila Tequila, who took to her Twitter account to mourn the lose of her “wifey” after hearing the news of her passing. Casey Johnson was only 30 years old:

The Jets announced Monday that Casey Johnson, a daughter of the team’s owner, Woody Johnson, had died in Los Angeles. The cause of the death was undetermined. Ms. Johnson was 30. Ms. Johnson, whose great-great-grandfather was a co-founder of the Johnson & Johnson health products manufacturer, grew up on Fifth Avenue in Manhattan. She and her socialite cohorts, including Paris and Nicky Hilton, the hotel heiresses, were featured in the 2002 documentary, “The It Girls.” “The Johnson family is mourning its tragic loss, and asks for privacy during this very difficult time,” the Jets said in a statement. Ms. Johnson’s death capped several months in which she drew tabloid headlines for her tempestuous relationships and public behavior. In a rambling, racy Web video last month, Ms. Johnson and Tila Tequila, a reality television star, announced their engagement. The couple, never bashful in their displays of affection, became favorites of the paparazzi. “This is a very heartbreaking time for me,” said Ms. Tequila, on Twitter, requesting privacy “as I deal with the loss of my Fiancé Casey Johnson.” She added that her “heart is shredded.” Diagnosed with diabetes as a child, Ms. Johnson wrote a book with her father and mother, Sale Johnson, in 1994, “Managing Your Child’s Diabetes” (Mastermedia). Her illness drove her father’s passion for treating the disease, and he serves as chairman of the Juvenile Diabetes Research Foundation. Ms. Johnson is survived by her parents, two sisters and a daughter, Ava-Monroe, whom she adopted from Kazakhstan in 2007. The news of her death was first reported by TMZ.com.

To be honest, I don’t know much about Casey Johnson because as much of a tabloid fixture as she was, she ran around more in socialite circles than celebrity circles. It was only when she announced her engagement to Tila Tequila that I became familiar with who she was. And speaking Tila, here are a series of her mournful tweets as posted as soon as the news broke of Johnson‘s death (it turns out that Tila found about about her death the same way we all did — online. She had not been with nor seen her fiancée for many days) wherein she begs for privacy so she can tweet about her sadness:

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 / This is a very heartbreaking time for me. I just want some pricacy as I deal with the loss of my Fiance Casey Johnson. I’m heart is shredded / I just got news that my fiance is not dead but currently in a coma!!!

I love u so so much and we will Marry when I see U in Heaven my Wifey / I can’t stop these haunting visions of her and I.

I don’t know that I would spend all night tweeting messages to fans after finding out that my fiancée had passed away but, well, this is clearly how Tila Tequila rolls. My deepest condolences go out to Casey Johnson‘s family and friends, it is a tragic loss to lose a loved one at such a young age … no matter what the cause of death.
