Troy Davis mourned as a martyr by 1,000 in Ga.

He recalled Davis, the uncle who had been in prison his entire life, spending long hours with him on the phone helping with homework, particularly math. Davis-Correia, whose mother is Davis' older sister, said the family always knew when he had tests in school because Davis wrote them all down on his calendar, the same calendar he filled with the birthdays of all his friends and supporters. And he said his uncle would have wanted a note of celebration at his funeral.

"You really shouldn't be sad all the time, you should be happy and be positive," Davis-Correia said. "That's the attitude my uncle instilled in me."

Amnesty International, which worked for years to exonerate Davis, urged its supporters worldwide to remember him Saturday by wearing black armbands and "I am Troy Davis."

The advocacy group's U.S. director, Larry Cox, spoke from the dais behind Davis' casket Saturday urging those who fought to spare his life not to give up until America ends its use of the death penalty.

"If you thought you saw us fighting to save Troy Davis, now that we've been inspired by Troy Davis, you ain't seen nothing yet," Cox said.
