Navajo crash, CLW

Tragic accident north of Clearwater (FL) Airpark thurs. 8/21 evening. Twin
Navajo apparently on approach to rwy 16 crashed and burned in a residential
area, killing two (father and son) and seriously injuring 1. They were
returning from N. FL according to newspaper. Weather was rain storm, not
sure how severe; witnesses reported hearing engine failure; fuel guy at CLW
who took advisory request said they dropped straight down like a pancake as
if from a strong downdraft. Any more info out there on this?
My sympathies go out to family and friends on their loss.
