(Reuters) – A Minnesota police officer was charged with second-degree manslaughter on Wednesday for the fatal shooting of a black motorist that sparked outrage when the moments that followed were broadcast on social media.

St. Anthony police officer Jeronimo Yanez broke the law when he shot and killed Philando Castile in Falcon Heights, a St. Paul suburb, during a traffic stop, Ramsey County Attorney John Choi told reporters. Yanez’s attorney could not immediately be reached for comment.

The prosecutor said Yanez feared that Castile was reaching for a gun he had just calmly said he had in his possession, moments before being shot seven times by the officer.

A moaning Castile’s final words after being shot were, “I wasn’t reaching for it,” according to Choi, who said the conversation was picked up by a microphone Yanez was wearing.

Starting about 40 seconds after the shooting, Castile’s girlfriend, Diamond Reynolds, who was sitting in the vehicle’s passenger seat, streamed images of a bloody Castile on Facebook live, and the recording went viral on social media.

The incident began a little after 9 p.m. local time on July 6, when Yanez pulled Castile over on suspicion of involvement of a robbery, Choi said. Castile had no involvement in the robbery, he added.

Castile then, in a non-threatening manner, told the officer about the firearm he was carrying, according to Choi.

Yanez interrupted and replied, “OK,” and placed his hand on his gun, then said, “OK, don’t reach for it then.”

Castile tried to respond but was interrupted by Yanez, who said, “Don’t pull it out.”

Castile and Reynolds both responded that he was not pulling the gun out.

Yanez then screamed, “Don’t pull it out,” drew his own gun, and fired seven shots in rapid succession.

When officers and paramedics were moving Castile, they found a 40-caliber semiautomatic handgun in his right front pocket that had a loaded magazine but no round in chamber.

At the hospital, Castile’s wallet contained a driver’s license and his permit to carry a pistol.

“I have given officer Yanez every benefit of the doubt on his use of deadly force,” Choi said during a press conference on Wednesday.

“But I cannot allow the death of a motorist who was lawfully carrying a firearm under these facts and circumstances to go unaccounted for.”

Yanez has also been charged with two felony counts of dangerous discharge of a firearm that endangered the safety of Reynolds and her four-year-old daughter, who was also in the car at the time.

Asked why he did not charge Yanez with more serious offense, Choi said this was the “highest, most provable offense” beyond a reasonable doubt based on the facts of the case.

Choi said he met with Castile’s family on Tuesday night and informed them of the charges against Yanez.

“The family is pleased with that recommendation because we know what type of charges could be brought about by the statutes of Minnesota laws,” Castile’s mother, Valerie Castile, told reporters. “We’re here in solidarity, my family and I, to support that decision.”

She also called for peace as the legal process continues.

Castile was remembered as a gentle man who was so smart he was considered over-qualified for his cafeteria supervisor job at a Minnesota public school, where kids loved him, according to friends, family and others who knew him.

Because the case is ongoing, Choi said he would not release the video and audio from the squad car.

Yanez will make his first appearance in criminal court on Friday afternoon in Ramsay County Law Enforcement Center.
