Tuesday would have been Trayvon Martin's 18th birthday.
He was the unarmed teenager who was shot last year in a confrontation with George Zimmerman.
Zimmerman says he acted in self-defense.
Also Tuesday, Zimmerman was in court, where a judge denied his attorney's request to delay this summer's murder trial.
George Zimmerman's brother -- Robert Zimmerman Jr. -- tells CNN's 'Piers Morgan Tonight' they have faith in Zimmerman's attorney, Mark O'Mara.
Mark is going to turn every stone, we always had confidence in him to zealously represent George's interest, and if trial will go forth June 10th as it's on the schedule now, then it will be a prepared attorney that represents my brother," Robert said. "We all want closure in this case, but we do want George to get a fair trial."
In honor of what would have been Martin's 18th birthday, a peace rally took place in Sanford, Florida, the city in which Martin was shot.
