Despite her illness, Martina fought tirelessly and selflessly to prove that her brother, Georgia death row inmate Troy Davis, was innocent.
Sadly, Georgia executed Troy anyway on September 21, 2011, despite compelling evidence that he may indeed have been innocent. Martina followed him to her own grave shortly thereafter.
I generally don't believe in an afterlife. However, at times like this, I wish there were one, so that Martina and Troy could be together forever, enjoying their strong and inspiring sibling bond through eternity. Maybe they are.
