US police kill black father with barrage of bullets in Walmart car park

Police have killed an African-American father of three using two dozen bullets in the car park of a Walmart supermarket in California, authorities and his lawyer said.

Diante Yarber, 26, was unarmed and parking his car in Barstow, about two hours east of Los Angeles, at the time of the incident on April 4, according to his lawyer Lee Merritt.

Mariana Tafoya, 26, one of the four passengers in the car, is recovering in hospital from bullet wounds, Mr Merritt told AFP.

He said police officers shot a total of 30 bullets, two dozen of which hit Mr Yarber.

The lawyer plans to file a complaint this week for "excessive policing" on behalf of Mr Yarber's family.

Police indicated officers had responded to reports of a "suspicious vehicle."

"The suspect/driver began accelerating his vehicle in reverse, striking a police vehicle. The vehicle then accelerated forward toward the officers, and then accelerated in reverse toward officers and striking another patrol vehicle," police said.

"Afterward, an officer-involved shooting ensued."

Mr Merritt, the lawyer, said three police cars had responded to the incident.

Two other passengers in Mr Yarber's car were arrested on site and later released. One was lightly wounded during the incident, and a police officer was also lightly hurt.

The San Bernardino County Sheriff's Officer indicated that officers thought Mr Yarber was a car theft suspect.

However, Mr Merritt indicated the vehicle, a black Ford Mustang, belonged to Mr Yarber's cousin.

"The institutional racism that got 2 blk men arrested at @Starbucks got #DianteYarber killed for looking suspicious outside of @Walmart 30+ bullets poured into a car filled with people posing no threat to anyone!" the lawyer wrote on Twitter.

However, Mr Merritt said his planned lawsuit would not be a racism claim.

Walmart did not immediately respond to requests for comment, but the Barstow store will be closed during the investigation.
