We were in Marigot at the marina when this happened and arrived on the scene shortly after the van went in the water. There were a lot of sirens and a large crowd had gathered. It definitely went in nose first and there was at least one injury. One person was on the ground with what looked like an IV and we heard another had a broken arm (but didn’t see that person so not sure about that). When we were taking a taxi later to Maho beach our driver told us that the driver of the van got out but left it in gear and it accelerated and went over the bank. It must have been traveling at a decent rate of speed as it had to jump the curb and make it over some sizable boulders to get to the water. He also told us it was the local kids swimming in the water that rescued at least one person and most likely saved his life.
