Students in Cutler Bay form a "TM" on a football field in support of Trayvon Martin March 23.
Sunday, Feb. 26: Trayvon Martin, 17, a junior at Miami’s Krop Senior High School, is fatally shot in the chest by neighborhood watch volunteer George Zimmerman, 28, in a gated community in Sanford, according to police. Martin was visiting with his father at his father’s girlfriend’s home there and was returning from a 7-Eleven when Zimmerman followed him from his car and a fatal confrontation ensued, police said. Zimmerman told them that he shot Martin in self-defense, they said. He is neither arrested nor charged.
Friday, March 9: The story gets widespread media attention for the first time, as Martin’s parents hold a press conference. Father Tracy Martin said that "my son left Sanford, Florida in a body bag, while George Zimmerman went home to sleep in his own bed." Sybrina Fulton said “as a mother, my heart is broken.”
Several callers told police that they saw a fight and heard a gunshot at The Retreat at Twin Lakes on the night of Feb. 26. The Orlando Sentinel reported that Zimmerman was bleeding from his nose and head when authorities arrived. Sanford Police Chief Bill Lee Jr. said that evidence and testimony may corroborate Zimmerman's story, because he had a bloody nose and had grass clippings on the back of his shirt, like he had been in a defensive posture. Lee said a dispatcher asked Zimmerman, after he called them after seeing Martin, “to wait until we got there,” but he did not.
Martin’s parents and their lawyers called on police to arrest Zimmerman and release details.
Tracy Martin told The Miami Herald that his son was out of school because he was suspended for a week, and that he brought him to Sanford “to disconnect and get his priorities straight.”
Sunday, March 11: Martin’s parents demand justice in their son’s shooting in a gathering at the Antioch Missionary Baptist Church in Miami Gardens. Family and friends said a prayer and read a poem for the teen. "Not only did I lose a son, I lost a dear friend," Tracy Martin said outside the church.
At this point, police have said that Zimmerman called police and reported Martin as a suspicious person in the neighborhood, before following Martin from his car. "I think it's just profiling, I think it has something to do with the fact that he was a young black African-American kid," Fulton said. "I don't know why he became suspicious."
Zimmerman, who told police that he shot Martin in self-defense, has not been charged at this time.
"We need answers and we need justice," Tracy Martin said. "Not only are we looking for an arrest, we're looking for a conviction."
Monday, March 12: Lee said that his department had nearly completed “a thorough and fair investigation” into Martin’s shooting, but said police did not have anything to dispute Zimmerman’s self-defense claim. “Until we can establish probable cause to dispute that, we don’t have the grounds to arrest him,” Lee said of Zimmerman.

Ben Jealous, the president of the National Association for the Advancement of Colored People, called for the Sanford police chief to resign and for federal authorities to come in and take over the police department because of “a pattern and practice of discrimination.” About 350 people attended a town hall meeting at Allen Chapel AME Church in Sanford, and those who cannot fit indoors rally and chant “I am Trayvon Martin” outside.

A “Million Hoodie March” is held in Union Square in New York. Hundreds of people attend, including Martin’s parents.
Thursday, March 22: About 300 to 400 students walked out of Miami’s Carol City High School to protest that Zimmerman was not arrested. The protest brought traffic on nearby streets to a stop as students marched for several blocks, chanting and pounding on car hoods. The school’s principal approved the demonstration, which started on campus, but students were not given permission to leave school.
Lee temporarily stepped down as Sanford’s police chief amid mounting public criticism of his department’s handling of the case and outrage that Zimmerman had not been charged. He acknowledged that his presence as the chief had become a distraction, while standing by his department and its investigation. Tracy Martin said “the temporary step-down of Bill Lee is nothing” and said he wanted Zimmerman arrested and convicted. The Rev. Al Sharpton held a rally with Martin’s parents in Sanford that was attended by thousands. The rally was the latest of many held across the country over the previous week.
