LOS ANGELES — Three of Casey Kasem’s children and his brother are suing the late radio host’s widow, accusing her of neglecting his medical care and hastening his death in 2014.

The lawsuit, filed Wednesday in Los Angeles County Superior Court, alleges that Jean Kasem moved her husband between medical facilities, hospitals, a Las Vegas hotel room and a bungalow in Washington state, all in an effort to isolate him from his children and medical professionals.

In his final months, as his children from a first marriage and his wife battled in court over his care, the “American Top 40” host often went without a hospital bed, intravenous medicine, adequate nutrition and hospitalization, the lawsuit alleges.

With such “grossly harmful mistreatment,” he developed at least four infections that led to his death on June 15, 2014, at 82, according to the complaint.

Jean Kasem had her husband buried in Norway in an unmarked grave, according to the lawsuit. No autopsy was performed.

The children, who were born during Kasem’s marriage to Linda Myers, and Kasem’s brother, Mouner Kasem, are seeking $250,000 in damages for elder abuse, the maximum allowed by law.

The suit also seeks unspecified damages for wrongful death and infliction of distress.
