The shipwreck may have been known to one or more local watermen before its discovery by archaeologists. During the 1996 excavations, Texas Historical Commission archaeologists observed direct evidence that one of the four bronze cannons known to have been on "La Belle" had been removed from the wreckage some time before the 1995 discovery of the wreck, possibly decades earlier. It was surmised that this may have been the action of a local shrimper who may have accidentally snagged and recovered the gun in his nets. The whereabouts of this cannon remain a mystery, and no other clear signs of prior artifact recovery were observed at the wreck site.
