Yesterday morning, police killed a Bronx man who had been threatening to kill his family, allegedly saying, "I have to kill the children and my wife and send them to heaven. I don't care about killing myself and going to hell." Mauricio Jacques, 35, had been holding his wife with one hand while a 10-inch knife was in the other; their three children, ages 5 to 11, were also present. Cops had tried to negotiate with him for an hour; WCBS 2 reports that Jacques agreed to surrender but " then lunged with a 10-inch knife at officers, who tried to subdue Jacques with a stun gun and rubber pellets. Undeterred, he stabbed an officer in the abdomen of his protective vest and slashed another's vest near the neck." The cops used the Taser on him again, but that didn't stop him, so one cop grabbed his wife while two others fired six shots at Jacques. Last week, the police fatally shot a woman who slashed a police officer.
