Yeah. There are some speculations (from people that have rented boats on the same lake) that maybe she was trying to help her son back in the boat and was restricted by the life jacket so threw it on board and then couldn’t get herself on board and drowned
But I don’t know if this is true
I think adults a lot of the time underestimate the power of water and overestimate their swimming skills
I always say if there is a life jacket available then wear it, regardless of how good a swimmer you think you are.
