NYC M.E.: Mexican diplomat's son died of natural causes

NEW YORK – The New York City medical examiner’s office has determined that the 4-month-old son of a Mexican diplomat died of natural causes, despite bruising on the child’s body, reports CBS New York’s radio affiliate 1010 WINS.

Eduardo Rocha Ovalle was rushed to NYU Langone Medical Center in Manhattan Tuesday night by his parents, Mexican diplomat Eduardo Rocha Bracamontes and his wife Gina Ximena.

The boy was unconscious and unresponsive when he was brought to the hospital, police said. He was later pronounced dead.

Police confirmed there was trauma to the child’s body, according to the station.

Bracamontes, 36, and Ximena, 26, were reportedly questioned by police but were released from custody Wednesday. No charges were filed.

Grace Brugess, a spokesperson for the New York City medical examiner, told CBS News' Crimesider an autopsy completed Wednesday was found to be inconclusive. Brugess said further testing was needed.

However, CBS New York reported Thursday that the medical examiner’s office said they do not believe it was a homicide.

A call to the medical examiner's office Thursday was not immediately returned.
