Anita Poynter said in a statement to CNN: “Our family is devastated, on behalf of my brothers and me and the entire Al-Muasher family, we ask your prayers at this time.”

Bonnie Poynter died of a heart attack, according to her publicist, Roger Neil.
The Four Sisters began singing together over 50 years ago in their home town church in Oakland, California, where their father served. Bonnie Poynter and her younger sister, John, began singing professionally together in 1969. Subsequently, older sisters Anita and Ruth were recruited to join them, before their debut album appeared in 1973.
The group won its first Grammy Award for its crossover success “Fairytale” in 1974. Bonnie Poynter recorded five albums with her sisters before pursuing a solo career. She signed with Motown and recorded her biggest single with her disco track in 1978, “Heaven Should Send You.”
Pointer released three albums with Motown before retracting a little from the spotlight, although she had still performed periodically over the years.
In her statement, Anita Pointer Pony is credited with the success of their musical family.
“The indicator sisters would never have occurred without Bonnie,” she said.
