Ax murder victim’s devastated family left searching for answers

The family of a 20-year-old mother brutally hacked to death in a Brooklyn apartment was distraught and emotional Sunday morning as they searched for answers.

“I don’t know why he did it. Maybe he don’t want no witnesses,” Savannah Rivera’s grandmother, Elsa Collazo, said Sunday.

Rivera, a pregnant mother of a three-year-old, was nearly decapitated in a fatal ax attack early Saturday morning that also left Angela Valle, 21, clinging to life.

Cops have charged Valle’s ex, 34-year-old Jerry Brown — known as “Grim Creepa” and “Mr. 187” on social media — with murder, attempted murder and weapons possession.

A distraught Collazo, who talked to The Post while mopping her kitchen floor in a nightgown, said she had gone to the morgue Saturday to see her granddaughter.

Two of Rivera’s aunts, whose faces were wet from tears did not want to give their names, refused to speak to a reporter at first. They stayed quiet as they sat and sobbed in the living room of grandmother’s fourth-floor apartment.

But one woman couldn’t hold back her anger and eventually blurted out, “They are going to kill him! He’s dead! He better stay in jail! That mother—-er!”

Neighbors of Valle said they didn’t hear anything from her apartment as Brown allegedly chopped at the women.

“I didn’t hear no fighting,” a man from the building, who refused to give his name. “I just saw the blood in the hall. The hall was covered in blood. I just ran back in and waited for the cops.”

Neighbors said they had seen Valle on the elevator but didn’t know her.

Brown was at an area hospital Sunday, according to police, who would not say which facility. Sources said Saturday Brown was in psychiatric lockup.

Valle remained at Elmhurst Hospital in critical but stable condition.
