Singer and 'American Idol' alum Mandisa's cause of death revealed

A medical examiner confirmed the cause of death Tuesday for Christian singer Mandisa Hundley, who was found dead in her Tennessee home on April 18 at the age of 47.

Dr. Feng Li told The Nashville Tennessean, part of the USA TODAY Network, that an autopsy showed the Grammy-winning "Overcomer" singer died from complications of class III obesity. Her manner of death was listed as natural, Li said.

A publicist for Mandisa said they were just learning of the autopsy findings Tuesday and directed media inquiries to her family.

The Tennessean requested a copy of the singer's autopsy on April 19 but had not received the document as of Tuesday.

Born in Citrus Heights, California, Mandisa Lynn Hundley was a member of the famed Fisk University Jubilee singers in Nashville, where she graduated with a bachelor's degree in music in 2000.

"Mandisa was a voice of encouragement and truth to people facing life’s challenges all around the world. She wrote this song for a dear friend who had passed in 2017. Her own words say it best.

"American Idol" remembered the late singer and former contestant weeks later, with former contestants Colton Dixon (Season 11), Danny Gokey (Season 8) and Melinda Doolittle (Season 6) came together to sing Mary Mary's "Shackles (Praise You)," a song Mandisa performed on Season 5 of "Idol."
