Martin, 17, was carrying iced tea and candy as he walked from a convenience store to the home of his father’s fiancee in Sanford, Florida. Neighborhood watch captain George Zimmerman spotted the teenager and called 911 to report “a suspicious person” in his neighborhood.”
A scuffle broke out, but there were no direct witnesses. Moments later, neighbors reported hearing gunfire.
Zimmerman claimed Martin hit him, knocking him to the pavement. Zimmerman contends that he took out his gun and shot Martin in self-defense. Critics said Zimmerman was unjustified in confronting the unarmed teenager, particularly since Zimmerman disregarded a police dispatcher’s advice to stop following Martin.
In July 2013, Zimmerman was acquitted of a second degree murder charge, igniting protests.
The image of Martin wearing a hoodie became iconic. Professional athletes donned hoodies, and protestors repeated the mantra: “I am Trayvon Martin” to express solidarity and outrage.
Martin’s death inspired then-President Barack Obama to deliver a heartfelt message to Martin’s parents, saying, “If I had a son, he’d look like Trayvon.”
Writer, producer and director Ava DuVernay took a moment Sunday to remember Trayvon Martin before heading to the Academy Awards.
“Our hoodies are still up and the movement is still strong,” she wrote on Twitter.
After Zimmerman was acquitted, three activists — Alicia Garza, Opal Tometi and Patrisse Cullors — created the hashtag #BlackLivesMatter in protest.
Since then, the deaths of several African-Americans at the hands of police kept the “Black Lives Matter” movement in the public eye.
Here are some of the cases that led to protests, and kept alive the national conversation about the deaths of black Americans, police conduct, and what critics say is inequality in the justice system
Eric Garner, 43
Died on July 17, 2014, in Staten Island, New York
Police tried to arrest Garner, a father of six, in front of a store for allegedly selling cigarettes. Garner raised both hands in the air and asked officers not to shoot him.
The New York Police Department prohibits the use of chokeholds.
Garner, who had asthma, repeatedly said, “I can’t breathe! I can’t breathe!” as officers restrained him on the ground.
Police said he suffered a heart attack and died en route to a hospital. The death was ruled a homicide.
The jury later declined to indict Pantaleo, sparking protests and “die-ins.”
Michael Brown, 18
Died on Aug. 9, 2014, in Ferguson, Missouri
Brown, an unarmed teenager, was walking with a friend in the middle of the street when Ferguson police officer Darren Wilson approached them and told them to walk on the sidewalk in the St. Louis suburb.
From that point, the narratives vary. Authorities said Brown attacked Wilson and tried to take his gun. Some witnesses said Brown was surrendering with his hands in the air to indicate he was unarmed when Wilson shot him. Wilson fired his gun 12 times, documents show.
In November 2014, a grand jury decided not indict Wilson — a decision that led to heated and sometimes violent protests and clashes with authorities.
The Justice Department also found that local police had excessively stopped and ticketed black residents, often citing them multiple times in a single stop. The DOJ said “many officers” apparently viewed some of the city’s black residents “less as constituents to be protected than as potential offenders and sources of revenue.”
Walter Scott, 50
Died on April 4, 2015 in North Charleston, South Carolina
On the stand, Slager argued self-defense, telling jurors he shot Scott as he ran away because he posed a threat and could have turned around and charged him. A key piece of evidence in the trial was the cell phone video, which showed Slager chasing Scott, then shooting him in the back. Prosecutors estimated the two men were 18 feet apart when Slager opened fire.
Slager’s attorney, Andy Savage, had argued that the media created a “false narrative” of a white officer in Charleston who stopped a black motorist for a broken brake light and shot him as he ran away. The video, the attorney, contended, didn’t tell the whole story.
Slager’s re-trial on the murder charge is set for August.
Freddie Gray, 25
Died on April 19, 2015, seven days after he was fatally injured
Officers put Gray in a police van. At some point, somehow, Gray suffered a fatal spinal cord injury and died.
Between December 2015 and January 2016, the officers’ cases were heard in court. The jury deadlocked in the case against one officer, and three others — including the van driver — were acquitted. Charges against the three other officers were dropped in July 2016.
Months later, the DOJ found Baltimore police disproportionately stopped, searched and arrested black residents, and used excessive force against juveniles and those with mental disabilities, over at least a six year period.
