The New York City Medical Examiner's Office on Friday ruled the death of a Westchester caseworker as a homicide.

Maria Coto, 56 was seriously beaten in May after she knocked on the wrong apartment during a home visit in Peekskill.

Coto died about a month later.

The examiner’s office says she died due to complications from injuries to her head.

Hasseem Jenkins was originally charged with assault and is set to be arraigned on murder charges next Tuesday.

Jenkins is being held without bail at Westchester County Jail.
