{alltv} Diabetes cited in Johnson's death

LOS ANGELES (AP) -- The Los Angeles County coroner says socialite Casey Johnson's death was related to diabetes.

The coroner announced Thursday that the death of the Johnson & Johnson heiress was caused by diabetic ketoacidosis (kee-toh-as-i-DOH'-sis) -- a life-threatening condition caused by lack of insulin and sky-high blood sugar.

The coroner conducted Johnson's autopsy Jan. 5. Her body was found a day earlier in her Los Angeles home.

The 30-year-old daughter of New York Jets owner Robert "Woody" Johnson lived a party life. In December, she announced her engagement to bisexual reality TV star Tila (TEE'-lah) Tequila.
