Woman killed on her wedding day by drunk driver

There was a woman I had danced with who had recently given birth to their first baby (they hadn’t been married very long)
Both families met at a lake to celebrate the new baby
When the grandparents were leaving, she and the baby got out of the water to say goodbye and he stayed to get a last swim in
When she came back, no husband
Seemingly some stroke or heart attack
That story always haunts me
Reminds me of this story about one of the bodies found at receding Lake Mead ...
