The world is learning more bizarre details about the mystery death of Casey Johnson, heiress to the Johnson & Johnson fortune.

The 30-year-old wild child was found dead at her home Monday, and may have been dead for several days. A maid was seen fleeing Johnson's home screaming, "She's dead!"

Casey Johnson was the girlfriend of MTV reality star Tila Tequila, who called her "Wifey." They said they were engaged and Tila showed off her 17-carat ring just three weeks ago.

Tequila announced Johnson's death on her Twitter page, writing: "Everyone please pray 4 my Wifey Casey Johnson. She has passed away."

She continued to mourn online Tuesday, posting: "I can't stop these haunting visions of her and I. We made such a lovely couple, only beginning to spend the rest of our lives together..."

Johnson's father is New York Jets owner Robert Wood Johnson.

She suffered from Type 1 diabetes and had lapsed into comas twice before.

In 2007 Johnson adopted a daughter, Ava, from Kazakhstan. She is being cared for by Johnson's family.
