Police in Austin, Texas are investigating the fatal shooting of a protester at an anti-racism march.
Garrett Foster was pushing his fiancée’s wheelchair at the protest when a car drove into the crowd, his mother Sheila Foster told US media.
As demonstrators approached the car, someone inside the vehicle opened fire on the group.
Mr Foster was taken to hospital, but was pronounced dead shortly afterwards. Police have arrested a suspect.
Tributes were paid to Garrett Foster on social media, and by Sunday afternoon an online fundraiser had raised more than $67,000 (£52,400).
Protests against racism and police brutality, and in support of Black Lives Matter, have been held across the US since the killing of George Floyd in May.
