ENGLEWOOD, N.J. (AP) -- Estelle Bennett, a member of the 1960s singing group The Ronettes, has died. She was 67.

Her brother-in-law Jonathan Greenfield confirmed the death.

Police found Bennett dead in her Englewood apartment on Wednesday after relatives were unable to contact her. The time and cause of death have not yet been determined.

The Ronettes — sisters Veronica, Ronnie, and Estelle Bennett and their cousin Nedra Talley — signed with Phil Spector's Philles Records in 1963.

Their 1963 hit, "Be My Baby," was produced by Spector and epitomized the famed "wall of sound" technique he developed.

The Ronettes split around 1967 and were inducted into the Rock and Roll Hall of Fame in 2007.
