AUSTIN -- Austin police say a crowd attacked and killed a passenger in a vehicle that had struck and injured a child.
Police identify the man who died as 40-year-old David Rivas Morales of Austin.
The girl has non-life threatening injuries.
Police say the beating started Tuesday night after the car struck the child as it entered an apartment complex parking lot. The driver got out to check on the girl, believed to be about three or four years old, and was confronted by several people.
Morales was attacked when he tried to help his friend. The driver is cooperating with investigators.
Police believe as many as 3,000 people were at the city-sponsored Juneteenth celebration, but as few as two or as many as 20 carried out the attack.
Juneteenth marks the date General Gordon Granger arrived in Galveston in 1865 to share the news that slaves had been freed.
Police say the injured child is a girl, but a Morales family friend said the child is a boy with long hair.
