Former “American Top 40” radio host Casey Kasem was located in Washington state on Thursday, three days after a California judge ordered an investigation into the ailing 82-year-old’s whereabouts.

Kasem’s condition was not known immediately but his daughter Kerri, who was appointed as her father's temporary caretaker during a hearing Monday, reportedly said that locating him was the first step in bringing him back to Los Angeles. Kasem’s health had reportedly deteriorated in recent years and, according to court filings, he is suffering from a form of dementia known as Lewy body disease, which was previously diagnosed incorrectly as an advanced form of Parkinson’s disease.

"We have received confirmation that Casey Kasem has been found. The family has grave concerns about his health and will do everything in their power to bring him back home," Danny Deraney, Kerri’s publicist, reportedly said.

Santa Monica police Sgt. Mario Toti told Associated Press that Kasem was located by the Kitsap County Sheriff's Department on Wednesday, hours after Kasem's children filed a missing person's report.

Los Angeles Superior Court Judge Daniel S. Murphy on Monday ordered an investigation into the whereabouts of Kasem, as it reportedly emerged that he had been taken away from Los Angeles without his children's knowledge. Murphy also scheduled a hearing for June 20 to receive updates about Kasem’s health and wellbeing.

According to court filings, Kasem’s wife of 34 years, Jean, had been in control of his medical care and denied three of his children, including Kerri, from a previous marriage, any access to Kasem in recent months.

Kasem gained fame with his radio shows, "American Top 40" and "Casey's Top 40," and was the voice of Shaggy in the cartoon "Scooby Doo."
