"It was like the heart just sat down"

The words that I've bolded from the article in The Indianapolis Star captured exactly what I've been feeling about the shooting at the Sikh temple.

"Jatinder Mangat, 38, Racine, said his uncle Satwant Singh Kaleka, the temple's president, was one of those shot at the temple, but he didn't know the extent of Kaleka's injuries.  When he later learned people had died, Mangat said "it was like the heart just sat down."
"This shouldn't happen anywhere," he said.
