MIAMI -

Police said more than 5,000 people filled Bayfront Park in Miami Sunday afternoon to rally in support of Trayvon Martin, the 17-year-old who was shot and killed in Sanford, Fla. in February.

Martin's parents, Sybrina Fulton and Tracy Martin, joined civil rights and political leaders, such as Rev. Al Sharpton at the event.

"We've been a lot of places but this means the most to us," Fulton said.

Former Miami Heat great Alonzo Mourning showed up to the rally saying "There's strength in numbers." Mourning brought along his 15-year-old son who was one of many wearing a hoodie in memory of Trayvon.

Civil Rights activist Jesse Jackson got the crowd on it's feet.

"The real question is how do we turn pain into power," Jackson said.

The death of Trayvon is personal for many South Floridians who attended the rally. The teen was from this area and so the crowd was filled with classmates and friends. They told Local 10's Sasha Andrade that they are afraid any one of them could be next. The many people at the park became one in memory of the one who wasn't there.

"I am Isaiah Thomas but today I am Trayvon Martin," said the former NBA All-Star and FIU basketball coach as he pulled a hoodie on over his head.

R&B singer Betty Wright performed a song at the rally she said she wrote after the death of her own son. The song included lines that said the death of a black woman's son is just as important as the death of a white woman's son.

Miami-Dade County Public Schools Superintendent Alberto Carvalho also spoke to the crowd.

"You see, Trayvon is and was a son. He was my student, he was my child, he will forever be remembered as a child of God, of Miami-Dade," Carvalho said. "In his life, in his memory, in his spirit and soul, we will force the law, the rule, to do right by children in our community. It is time to educate our children one at a time, that is how you love the community, one child at a time. So to the family, we suffer with you, we pray with you, and we swear to you, never again, not for Trayvon, not for any of our children."

Attendees held signs bearing Trayvon's picture and the trademarked phrase "Justice," with a web address to the Advocacy Campaign for Truth by Sybrina Fulton and Tracy Martin, hosted by the family's attorney, Benjamin Crump. One woman wore custom earrings with Martin's picture on them and the phrase "Justice for Trayvon Martin."

Men with orange buckets collected donations for a newly created foundation to pay for the Martin family's legal and travel expenses. Sharpton announced the fund, saying they are fighting for the entire community and the community should make an "offering to the Trayvon Martin Foundation at justicetm.org.

The rally comes a day after thousands marched through Sanford.

Protesters say they will continue holding marches and rallies until an arrest is made.

Martin was shot by George Zimmerman, 28,  as he walked back to his father's fiancée's home in a gated community outside Orlando.

Zimmerman said the teen looked suspicious and that he shot him in self-defense after he and Martin fought.

It is being organized by Rep. Frederica Wilson.
