The stop quickly escalated.
The jury deliberated five days before reaching its verdict.
Jeronimo (yeh-RON'-ih-moh) Yanez was also cleared Friday of two lesser charges in the July traffic stop in a St. Paul suburb.
Choi took time to mention Yanez, the former St. Anthony Police officer who avoided a conviction, but will wrestle with what happened that fateful night for the rest of his life.
Yanez proceeded to tell him not to reach for it, to which Castile replied that he wasn't.
Castile was one of 963 people who police officers fatally shot past year, according to a Washington Post database tracking such shootings.
A Minnesota police officer was acquitted Friday in the killing of a black motorist that drew widespread attention when video of the shooting's aftermath was streamed live on Facebook.
Castile's death made national headlines last summer after his girlfriend broadcast the aftermath of the shooting on Facebook Live.
Yanez hired three prominent Minnesota attorneys - Paul Engh, Earl Gray and Thomas Kelly - who have all handled big cases before. In it, Castile can be seen bleeding to death in the driver's seat.
The 32-year-old Castile was black and Yanez, 29, is Mexican-American. Within seconds, Yanez fired seven shots.
"There should have been, in our opinion, a very, very different outcome", she said.
"You just killed my boyfriend!" "Because if the government can take your life and no one is held responsible, you are a second-class citizen, if not fully dehumanized in the eyes of the law". "The city intends to offer Officer Yanez a voluntary separation agreement to help him transition to another career other than being a St. Anthony officer". Prosecutors said Castile's last words were, "I wasn't reaching for it".
The jury spent almost 30 hours deciding Yanez's fate. But defense attorneys called their own witnesses to back up Yanez's claim that he saw Castile pulling the gun and that Yanez was right to shoot. Reynolds's daughter was sitting in a vehicle seat on the other side of the auto. One teacher testified at trial that Castile remembered which kids had allergies, and nudged students to finish their veggies.
Yanez reportedly stopped Castile because he fit the racial profile of a robbery suspect who had a "wide nose", as reported by the Washington Post.
Allysza Castile, Philando's younger sister, was more resigned while speaking to reporters. Castile's death, like Sterling's, set off protests across the country. Philando Castile was fatally shot by police.
"The City of Falcon Heights is going to continue to do what we've been doing in terms of the task force on policing and inclusion, and continue to move forward and develop the city to be a welcoming and inclusive community". Yanez is the first officer in Minnesota charged for an on-duty shooting since at least 2005, according to Philip M. Stinson, a criminologist at Bowling Green State University in OH, who studies arrests of officers and has kept data since that year.
The trial began in May. Around 13 police officers were on hand in the courtroom while the verdicts were read.
An officer who shot dead a man at a traffic stop has been found not guilty of second-degree manslaughter. He pleaded not-guilty to the charges.
Prosecutors also planned to address the media later in the day.
