Casey's Kids Name Half-Sister In Wrongful Death Lawsuit

Casey Kasem’s oldest children have added his youngest child — their half-sister — to a wrongful death lawsuit they filed last year against his widow, Jean.

Liberty Kasem, 25, is the only child born to Casey and Jean Kasem.

Jean was married to the longtime “American Top 40” radio host and voice over artist from 1980 until his June 2014 death at age 82 from a form of dementia and a severe bedsore.

CBS Local reports the amended Los Angeles Superior Court suit alleges Jean and Liberty Kasem are liable for wrongful death, elder abuse and negligent infliction of emotional distress. Casey’s brother, Mouner, is also aligned with his brother’s oldest children in the suit.

The complaint further alleges Jean Kasem committed intentional infliction of emotional distress by isolating her husband’s older children from their father before his death and that she breached a settlement agreement she had with one of his other daughters, Julie Kasem, by making it hard for her to visit with her father during most of the last six months of his life.

“Plaintiffs seek justice in this action through the only available means … for the grossly harmful mistreatment and isolation of their father and brother and for the hastening of his death,” the amended complaint alleges.

The plaintiffs in the lawsuit are Kerri, Julie and Michael Kasem and their uncle, Mouner. They fought Jean Kasem over visitation access before her husband died. She insisted that Casey didn’t want to see them or former business associates as his health declined.

Kerri Kasem was given temporary conservatorship powers over her father and had control of his medical care. The temporary conservatorship expired upon his death, but she was later appointed special administrator of her father’s estate.
