The gunman, Chad Hickman, was found dead in a wooded area near Whitlock Lake in Caldwell Township, the authorities said. A motive for the shootings was not immediately known.

The man bobbed and wove before lobbing a kick at a sea lion in San Diego last month, a video of the episode shows.

The attack left the victim with at least a dozen wounds as several bystanders rushed to intervene.

The Apache helicopter crashed in Salado, a small town about 20 miles from the military base, and set off a fire, the authorities said.
