Casey Johnson, the 30-year-old Johnson & Johnson heiress who was found dead, will be laid to rest later this week in a private funeral attended by immediate family.
The Johnson family wishes to thank everyone who has expressed condolences and support during this trying time,” says family spokesman Jesse Derris. “Your thoughts and prayers are deeply appreciated.
The socialite’s family has arranged for her body to be “flown back east to her final resting place,” Derris says. No other details were announced.
The family asks for a measure of privacy over the next several days as they mourn their loss,” adds Derris.
Johnson, who made tabloid headlines recently by getting engaged to reality star Tila Tequila, was found dead Monday in her Los Angeles home. Johnson had suffered from diabetes since she was a child and had battled drug problems in the past, though no cause of death has been determined and police found no obvious signs that she had taken illegal drugs.
Her family says that people can make donations in her memory to the Casey Johnson Memorial at the Juvenile Diabetes Research Foundation. “Casey struggled throughout her life fighting this disease, and she would want to see all of us continue that fight on her behalf,” says the family spokesman.
