Joni Sledge died of natural causes related to a pre-existing condition, according to law enforcement sources.
The 60-year-old was found deceased in her Phoenix, Arizona home on Friday, March 10.
The coroner ruled out foul play and an autopsy was not performed in accordance with state laws that do not require an autopsy if death is by natural causes.
Death by natural causes means the singer had a pre-existing condition or illness that would likely result in her death, such as a heart condition or kidney failure.
Her publicist issued a conflicting statement insisting she had not been ill prior to her death.
The singer was a member of 1970s disco group Sister Sledge. Although the group only had 2 hit songs (“We Are Family” and “The Greatest Dancer”), they are considered icons of the disco era in America.
Joni, Debbie, Kim and Kathy Sledge formed Sister Sledge in 1971. Kathy left the group in 1989 to pursue a solo career and raise a family.
When sisters Debbie and Kim took a break from performing, Joni, center, continued touring with her niece Camille, left and her cousin Amber Sledge, right, as Sister Sledge.
In a statement to fans, Debbie and Kim Sledge write:
“Sister Sledge will continue with their 2017 concert schedule. Sister Sledge – Debbie, Kim and the Sledge family would like to express our deepest gratitude to all who have extended their love and support during this difficult and challenging time of mourning, in the wake of the passing of our beloved sister Joni Sledge.
“Joni was a beautiful person, phenomenal artist and producer, a brilliant business woman and a powerhouse! One of her greatest loves and joys was performing live with her family. In the spirit of Joni’s powerful strength of character, zest for life and spreading joy through music, we are committed to continuing her legacy.”
