(CNN) -- The final, violent moments in the life of their son, Trayvon Martin, no longer dominate the national news, as they once did. Tens of thousands no longer attend rallies demanding justice for the slain teenager; pundits no longer debate the case on every media platform imaginable. What once had been the big story has increasingly become yesterday's news. But Sybrina Fulton and Tracy Martin haven't stopped fighting. One year ago Tuesday, they were grieving and relatively anonymous parents, trying to come to grips with the sudden death of their 17-year-old son. But in time, they became celebrities of sorts in a world of gun violence and vigilante justice.

That's when, and where, then-28-year-old neighborhood watch volunteer @placeholder spotted him.

What happened between then and when @placeholder fatally shot the teen is subject to dispute, one that could be settled by a jury starting June 10, when Zimmerman is set to go on trial on a second-degree murder charge.

Even as they continue to fight, Trayvon Martin's parents acknowledge that -- after months in the spotlight, trying to ramp up pressure on authorities to go after @placeholder -- much about their son's case is now out of their hands.
