The veteran musician was hospitalised in late April (15) after King's daughter Patty reportedly filed a police report alleging his manager Laverne Toney refused to get the star medical help.

King was told he had suffered a minor heart attack and was later discharged following treatment.

Now his other daughter Karen Williams has filed legal papers asking to be granted guardianship of his estate, according to TMZ.com.

In the papers, she reportedly accuses Toney of failing to give her father the care he needs and keeping his friends and family away.
