According to witness reports at approximately 4:45 pm on 10/20/2013 four jet skis attempted to pass through the Swing Bridge connecting Port Isabel and Long Island Village. The swing bridge is a floating barge that pivots on one side and swings open at the other, much like a door. The bridge is controlled by a series of cables and counterweights that an operator controls by releasing the weights (depending on whether he is trying to open or close it). The bridge opens wide enough to allow the passage of a boat barge, or can be opened to about the width of 132 feet wide. When closed, the Bridge allows for single lanes of automobile traffic flowing in both directions. The swing bridge operator opened the bridge approximately 30% for a small recreational boat after a request to pass was made between the captain and bridge operator. The boat was carrying witnesses. The Swing Bridge opens by request on the hour Monday thru Friday and every hour on the weekends. 
The Jet Ski tour guide from Breakaway Cruising made visual contact with the bridge operator. According to Guide he, “waved his hands and blew a mouth whistle,” in order to gain passage from Bridge operator. Two people both stated that bridge operator waved the Jet Skis to go around the swing bridge further away from the mobile sections and not pass through the mobile sections. However, the same time the boat passed through, subject began to pass and the other skis followed their guide. The swing bridge remained open briefly to allow the safe passage of the recreational boat and began to close immediately after their passage. The forth, and final, Jet Ski as they attempted to pass through the opening, both the Jet Ski and the passengers became wedged between the bridge and a wooden support pillar for the stationary portion of the bridge. The legs of both riders were temporarily pinched until occupant was able to grab his daughter and pull them into the water away from the bridge. They climbed onto a concrete support pillar under the bridge before being told by subject to get back in the water and on the Ski. While being caught between the bridge and the pillar, the Ski began to roll to the port side and the fiberglass began to crack. There was damage to the Jet Ski from the force of the bridge closing on it. When Eddie noticed that the bridge was stuck and not closing, he went back to the controls and opened the bridge, noticing a jet ski had been wedged between the bridge and pillars. Subject then grabbed the vacant Jet Ski and waited for the two passengers to remount. He tied the ski to his and towed them back to the rental location. All people at the scene were asked by  (the eye witness who was on the passenger boat) to wait for the South Padre Coast Guard to arrive to aid them, but Subject did not want to wait and left the scene. 
operator was taken to Brownsville Valley Regional Hospital where she was treated and released with bruising and minor scrapes to her legs. occupant did not seek treatment at the hospital but also received some bruising and scrapes to the legs. 
All of the following information was collected from several witnesses and victims of the accident. I did not witness any of the accident. I began my investigation on the 23rd on October. From my understanding and to the best of my knowledge and with collaboration of several witness reports, this is what I believe to be what happened on October 20, 2013 between 
the Jet Ski Passengers and the Swing Bridge.
