HALLANDALE BEACH, Fla. -

Dozens of people packed a park in Hallandale Beach Saturday to remember a teen they never met.

The candlelight vigil at Foster Park was aimed at reflecting on the killing of Trayvon Martin, 17, who was shot and killed while walking to a relative's home in Sanford. The teen was returning from a store where he purchased a bag of Skittles and a can of iced tea.

Martin was from Miami Gardens and was enrolled in classes at Dr. Michael Krop Senior High in Northeast Miami-Dade.

"This is about cold hearted murder," said Hallandale Beach resident Willie Thompson.

Participants carried candles, held hands, and sang songs as they emotionally recounted the events that led up to Trayvon's death.

"We have to pray that this young man did not die in vain," said Shauna Cox.

"I got a grandson. It could have been him," said B.J. Jordan, a retired police officer.

Martin was unarmed when he was shot in the chest and killed last month by a nightwatch captain who believed he looked suspicious.

George Zimmerman claimed self-defense in the confrontation in a gated Sanford development and has not been charged.

In Dania Beach, another march was held that mourners described as the Trayvon Martin movement.

"No matter what color you are, black or white -- all of us deserve the same justice. Equal justice and that's why we're here," one woman exclaimed.

Participants peacefully walked to a nearby store to purchase as many bags of Skittles and cans of iced tea as possible -- the very items Trayvon had the night he was killed.

Some people believe both events should serve as a teaching lesson for youth.

"I hope that other kids will learn from this and the whole world will be better," said Hallandale Beach resident Enease Jordan.
