Philando Castile shot by police in Minnesota, reports say, a day after Alton Sterling shooting

The death of another man at the hands of U.S. police has been caught on tape, according to multiple reports, with a video of the killing in Minnesota sweeping across social media platforms in the hours following the event.

The shooting of a man numerous reports identified as Philando Castile, 32, in the city of Falcon Heights on Wednesday, came just a day after the death of Alton Sterling, 37, in Baton Rouge, Louisiana.

Like Sterling's death on Tuesday, which was captured on video by a bystander, the immediate aftermath of Castile's shooting was also caught on camera - in this case, apparently live-streamed on Facebook, where it was reportedly viewed 50,000 times before being removed.

Castile's death prompted fresh anguish on Twitter, trending as Sterling's death had a day earlier.

CBS Minnesota and other news outlets reported that local police had confirmed the shooting of Castile, who later died at Hennepin County Medical Center.

Ted Haller, a reporter with Fox 9 in Minneapolis, live-streamed what he said was a press conference with police from the Minnesota town of St. Anthony, in which an unnamed officer said there was an ongoing investigation into the shooting, and that he had no further information other it had occurred during a routine traffic stop. The Minnesota Bureau of Criminal Apprehension had been informed, the officer said.

USA Today reported that St. Anthony Police's interim police chief Jon Mangseth said the officer involved in the shooting had been with the department for five years.

The Star Tribune and other news outlets said that a woman with Castile at the time of the shooting live-streamed via her phone on Facebook the minutes immediately after the event.

The Washington Post reported that the woman's Facebook page named her as Lavish Reynolds. It was not clear that that was the name of the woman in the video.

Reynolds' account appeared to have later been removed from Facebook, but the video was posted multiple times on Twitter under the hashtage #PhilandoCastile and #FalconHeightsShooting, as well as on other Facebook users' pages.

The graphic footage shows the woman and a man purported to be Castile in a car. The man is slumped sideways in the passenger seat, groaning and wearing a heavily bloodied t-shirt, while a police officer can be seen pointing a gun through the window of the car, sounding distressed and swearing as he shouts, "I told him not to reach for it! I told him to get his hands up!"

"You told him to get his ID, sir, his driver's license," Reynolds responds to the officer.

The woman speaks directly to the camera, saying calmly that the pair had been pulled over for a "busted tail-light" and that Castile had told the officer he had a firearm and that he was reaching for his wallet, then "the police just shot his arm off," the woman said.

It is apparent later in the video that the woman's daughter is in the car, and that the woman has been arrested.

CBS Minnesota reported that Castile's mother, Valerie Castile, said her son was a school cafeteria supervisor.

In Louisiana, meanwhile, the Department of Justice is leading the investigation into Sterling's death. The killing sparked protests on Tuesday, and NBC Philadelphia reported that police arrested people who marched through the city center.

It also emerged that the owner of the convenience store where Sterling was killed said he had his own cellphone video of Sterling being tackled by police before being shot multiple times.
