"At this time we do not know the cause of death or any further details," her rep wrote in a statement at the time. "We ask for your prayers for her family and close knit circle of friends during this incredibly difficult time."

The statement continued: "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. 'I'm already home. You've got to lay it down 'cause Jesus holds me now—And I am not alone.'"

Local police confirmed per RadarOnline.com that there was "no indication the death was the result of suspicious or criminal activity ."

Mandisa famously starred on Season 5 of American Idol alongside fellow contestants Katharine McPhee , Elliott Yamin , Kellie Pickler , Taylor Hicks and Chris Daughtry . Her first full-length album hit shelves in 2007 and was number one in Christian album charts.

In his own post, Hicks also wrote that Mandisa had been a " power house vocalist " and a "power house person" who he will miss "dearly."
