Police are accusing a man of killing a 35-year-old Westchester woman in her apartment while her baby was nearby.

White Plains Police Commissioner David Chong said it's believed the suspect is the father of the baby girl, Jamie, who was found at the crime scene. The baby is recovering from dehydration but is otherwise in good condition.

A relative told NBC New York that a cousin who had a key to the house discovered the woman, identified as Sabrina Durrah, after calling her and getting no response.

"It was a shock to us that she was murdered," said another cousin, Erwin Tollinger.

Chong said Michael Saunders of Yonkers was arrested Tuesday morning and charged with second-degree murder. He said Saunders had a relationship with Durrah, who worked as a nurse's aide, but they did not live together.

Chong said DNA tests have not been completed but Saunders is believed to be the father of Durrah's 4-month-old daughter.

Chong would not discuss how Durrah was killed or any motive.

There was no court record of an attorney for Saunders.

Durrah's funeral is scheduled for Saturday at 10 a.m.
