ABC News has learned Martin’s family will soon be notified that the Justice Department will not be filing charges against George Zimmerman, who shot the 17-year-old after a confrontation in 2012. Thursday marks three years to the day since Martin was killed.

Federal prosecutors concluded there is not sufficient evidence to prove Zimmerman, a neighborhood watchman in Sanford, Fla., intentionally violated Martin’s civil rights, sources told ABC News.

The case sparked intense discussions over race in America because Martin was walking to his home with only Skittles and an iced tea in his hands.
