Deputies James Slikker and Tracy Sizemore were in their fireboat, headed back to Marine Operations Headquarters across Newport Harbor after checking out a report of juveniles smoking marijuana on a local dock. They had tied up the craft, checked out the dock and encountered a seal lion that had tried to attack a boy. They enticed the sealion aboard their craft and headed into the bay to deliver the sealion to a place where it would be safe and not a threat.

Out in the harbor the boat’s emergency lights flashed, deck lights went on and off and the emergency pump and other equipment began turning on and off at random. The boat lurched to one side and seemingly stering itself.

The two seasoned Deputies left the bridge to see what was going on.
