A man from Troy, New Hampshire, was fatally shot by police on the Piscataqua River Bridge after he allegedly killed his wife and their 8-year-old child. The incident began when the man called 911 early Thursday morning to report that he had killed his wife. Police found the woman's body at their home and later located the man on the bridge, where negotiations failed, and he raised a firearm at officers, prompting them to shoot. The man's body fell into the river and was recovered. Police confirmed the child was found dead in the man's car but was not killed by their gunfire. The investigation is ongoing, with both New Hampshire and Maine authorities involved.
