The black man shot many times in the back by Wisconsin police officers is paralysed from the waist down, his father has said.
Jacob Blake, 29, was shot several times as he went to a car and opened its door in the city of Kenosha on Sunday.
The shooting sparked two nights of protests in the city, with buildings and cars set alight.
His father has now told a US newspaper that his son is paralysed – although doctors do not know if it is permanent.
Jacob Blake Snr told the Chicago Sun Times his son had “eight holes” in his body.
“What justified all those shots?” his father asked. “What justified doing that in front of my grandsons? What are we doing?”
Video footage of Mr Blake’s shooting, taken from across the street and shared on social media, shows the father-of-three leaning into the car and an officer grabbing his shirt, with seven shots heard.
His fiancée, Laquisha Booker, described how the children – who witnessed everything as they sat in the back of the car – were screaming as their father was shot.
Speaking to a local NBC channel, she asked why the police would shoot someone “who’s not armed, not giving you no problems”.
“You shot him numerous times for no reason, it didn’t take all that,” she said. “[You] disregard that my kids was in the car at all – and you knew that they were in there because I kept screaming that before y’all made it to the other side of the driver’s side to get him in the car.
“I’ve been yelling that the whole time, let me get my kids. So that’s not important to y’all. What’s important is killing somebody.”
Police said they were responding to a domestic incident, but it is so far unclear who called police and what happened before the video recording began.
But it comes as the US grapples with the treatment of African-Americans at the hands US law enforcement, as well as wider questions about racism in society, following the killing of another black man, George Floyd, in May.
Mr Floyd’s death sparked protests around the country, and abroad.
