An off-duty NYPD officer shot dead her baby son and the baby’s father in Brooklyn on Monday morning, before turning the gun on herself. Cops arrived at the scene after her 19-year-old son heard a dispute and called 911 after escaping through a window of the first-floor apartment. But by the time they got there, the cop, her 1-year-old child, and boyfriend were all dead. The bodies of the female officer and her baby boy were found face up on the bed in her bedroom. The identity of the officer has not yet been revealed, and police are still investigating a motive.
