An investigation was launched into the death of a local sailor on a Navy patrol boat, according to Navy Region Southwest.
Witness Steve Urschel said he saw Navy and Harbor Police boats stream to the B Street Pier at a high speed around 4 p.m. Tuesday.
There was frantic activity around the boat, possibly an attempt at life-saving measures, and then it stopped witnesses told NBC 7.
One sailor seemed very distraught.
"He looked very, very worried. There were other people around, filling around him, giving him hugs, patting him on the back trying to support him after what happened. Obviously it was not good," Urschel said.
Officials surrounded the area with crime tape, and a yellow tarp could be seen on the patrol boat.
Harbor police and Navy investigators were on hand gathering evidence and taking pictures.
Foul play was not suspected, according to Navy officials.
