thanks for the quick reply. Good to know the beach is close by.
I found a link to the story
More Caribbean Crime - Carnival Passenger Killed In St. Thomas : Cruise Law News
It appears that Magen's Bay is further north of Koki where the shooting occured and (duh) Trunk Bay is on St. John.
I know it is an isolate incident that could easily occur in my home town ... but one still wants to be cautious in taking their young children into an area where a problem has occured.
