Bonnie Pointer, former member of the Grammy award-winning 'Pointer Sisters' has passed away at the age of 69 due to heart attack.
Bonnie was one of the founding members of the group and the singer left the group in mid-1970s to pursue a solo career.
"Our family is devastated," her sister Anita told the Associated Press on Monday.
"On behalf of my siblings and I and the entire Pointer family, we ask for your prayers at this time."
Bonnie and her sister June Pointer originally performed as a duet and were later joined by their sisters Anita and Ruth.
The Pointer Sisters became popular in the 1970s and won the first of their three Grammy Awards for the song Fairytale in 1975.
Earlier this year, Anita and Bonnie Pointer released a single in memory of their sister June, who died in 2006.
Their sister Ruth is the only sibling still performing in the Pointer Sisters, joined by her daughter and granddaughter.
