”You could see his face. He still had hair on his head,”
Bacchus said.

IIRC from one of the "CSI"-type shows, hair and nails contiue to
grow for a bit after death.

As for the neighbors, I sympathize with them.
While I was in Los Angeles, a lady in the apartment next to me
died of a brain tumor and wasn't discovered for maybe a week or so
post-death.

I'd exchanged pleasantries a few times with the ex-schoolteacher.
And was shocked when I heard of her demise.

BUT, in a big city, folks learn to "mind their own bidness".
At the same time, I suspect the neighbors in this articles are
having some pangs of conscience like I did when I realized my
neighbor had lain dead about 30 feet from my abode with nobody checking
on her for about a week.

According to Wikipedia:

"It is commonly claimed that hair and nails will continue growing for several days after death. This is a myth; the appearance of growth is actually caused by the retraction of skin as the surrounding tissue dehydrates, making nails and hair more prominent."

Sounds reasonable.
