The mom of a little girl murdered by her own dad exclaimed “My baby is gone” as she was overcome by grief during a candlelight vigil for victims of a Brooklyn murder-suicide Wednesday night.

Olivia Callender, 27, had to be held up by loved ones on both sides of her, as she mourned the death of her 14-month-old daughter, Layla Briggs.

“My baby is gone,” the mom sobbed at the vigil outside of the Riverdale Osborne Towers in Brownsville. “She’s not coming back, my baby.”

Callender does not live at the building where Terrance Briggs, 27, shot and killed two other men and his little girl before turning the gun on himself.
