'My dad was killed in first hate-crime after 9/11'

In the wake of the 9/11 terror attacks, the US saw a sharp rise in hate crimes. The attackers targeted those they believed to be Arab Muslims.

The innocent victims included Balbir Singh Sodhi, an American-Sikh who had a beard and wore a turban and ran the family gas station in Mesa, Arizona.

His murder, four days after 9/11, was the first racially-motivated hate crime in the backlash of the attacks.

The BBC spoke to Balbir's brother, and for the first time, his son and the gunman.
