Sad Story Concerning Casey Kasem

The children of radio legend Casey Kasem say they're being kept away from their dad. TMZ.com says police were called to Kasem's Holmby Hills home in Los Angeles Tuesday after his three children, his brother and several others gathered outside of the property demanding to see him. Kasem's daughter Kerri Kasem says they used to see their father every week but have been denied that right by Kasem's second wife, their stepmother, former actress Jean Kasem. The 81 year old radio icon is reportedly ill with advanced Parkinson's disease. TMZ says Jean called police Tuesday and filed a trespassing report. Casey Kasem hosted the nationally syndicated Top 40 countdown show "American Top 40" and similar radio shows between 1970 and 2009 when he retired. The Detroit-born radio personality is also known for voicing the character Shaggy in the Saturday morning "Scooby-Doo" cartoon series.
