February 26: High school student Trayvon Martin is shot and killed in Sanford, Florida. He and the shooter, George Zimmerman, are identified the next day. Zimmerman claims he killed Martin in self-defense, and police do not arrest him or test him for drugs or alcohol.

March 9: The family of Trayvon Martin requests the release of 911 tapes from the night of the shooting, after a press conference the day before urging the arrest of Zimmerman for murder.
