Antoine Mattox, 32, of Andover Avenue, who was indicted Monday on a second-degree murder charge in the beating death of his wife, is scheduled to be arraigned this morning before Erie County Judge Sheila A. DiTullio, according to Erie County District Attorney Frank A. Sedita III.

Mattox has been in custody since he was arrested at a Rochester bus terminal after he allegedly fatally beat his wife Nedra E. Thomas-Mattox, 38, in their home on March 11.

E. Carey Cantwell, Mattox’ attorney, could not be reached Monday night for comment.

Mattox is an inmate at the Erie County Holding Center. He allegedly made incriminating admissions to Buffalo homicide detectives who went to Rochester to pick him up after his late afternoon arrest there.

The victim and her alleged killer had been married ten years. Nedra E. Thomas-Mattox was the mother of two girls and a boy. The Buffalo News disclosed Sunday that she had been staying at Haven House, a Buffalo shelter for domestic violence victims, from late December until sometime in February before she returned to the Andover Avenue home she shared with Mattox.
