Monday is the 12th anniversary of Trayvon Martin’s fatal shooting in Sanford, Florida, at the hands of George Zimmerman, and Sybrina Fulton, Martin’s mother, said she is still fighting for change.

“I still remember that I was in disbelief. Even though it’s almost 12 years, it seems like it was a few years ago,” Fulton said in a recent interview, recalling the night her son died while making his way home from a convenience store, according to a report.
