A tragic accident. Our thoughts go out to the family.
There are pictures of the tree at the link Acer posted:

It looks like a poplar and wasn't pollarded in recent years, If the
pictures show the right tree. It's difficult to work out how the
failure occured, as the failure point has been pruned out.
I agree with other posts that there should be a nationaly recognised
system where failures lead to loss of life or significant harm, so
that the evidence isn't cleared up too quickly, thus hampering any
hope of understanding why the failure happened. This is exactly the
kind of thing that our national arb organisations should be working
together on.
An assessment of failures, is important for the advancement of our
industry's understanding of why these occur. It's a pity that the
International Tree Failure Database project seems to have floundered
in Britain, since the original training session organised by the ISA
about 5/6 years ago. Hopefully, this can be resurected. Every
professional arb that inspects or clears up tree/ branch failures
could be inputting data, which would be an invaluable resource for the
advancement of our understanding of why trees/ branches fail.

Today's Saturday Telegraph added a few more snippets of information
about the tree -
Apparently it was 50ft tall and dropped a 1ft wide branch, oh, and
it had been pollarded last Autumn.
I still haven't managed to work out how a recently pollarded tree
managed to put on so much growth that the re-growth ended up 1ft
thick in only 8 months or so.
Does anyone from the area where this happened have some decent facts
for us?
regards,
Bettina
