The Oscar-winner's mother found the actress-turned-producer dead at her home in Little Rock, Arkansas on Wednesday (27Oct10).
The Pulaski County Coroner, Garland Camper, has stated that Blount most likely passed away two days earlier on Monday (25Oct10), but he ruled there were no signs of foul play.
Blount was best known for her work onscreen in 1982 movie An Officer And A Gentleman alongside Richard Gere, as well as her role in John Carpenter's 1987 horror Prince Of Darkness and TV show Profit.
Blount later stepped behind the camera and became a successful producer, sharing an Academy Award with her actor/director husband Ray McKinnon for their 2001 short film, The Accountant.
Blount's cause of death was not known as WENN went to press.
