NEW YORK (CBSNewYork/AP) — A 36-year-old man is expected to be arraigned Wednesday on a second-degree murder charge in the death of his girlfriend.

Police said a Daniella Mannino, 34, was found stabbed to death around 1:30 p.m. Tuesday in a bathtub at Brian Sohtz’s Brooklyn apartment.

The NYPD said Sohtz was arrested in Suffolk County. They said he was headed there when he called a relative who in turn called police.

Sandy Silverstein, a spokesman for Brooklyn District Attorney Charles Hynes, said the victim is the daughter of Joseph Mannino, who is director of the district attorney’s office services department.

Hynes will seek a special prosecutor in the case.

People who knew the victim are stunned.

“She was great. I knew her my whole life. Every day we’d talk about life, you know? Good mother, good person,” one acquaintance told CBS 2.

Mannino reportedly has a 12-year-old daughter.

It was not immediately known if Sohtz had a lawyer.
