People from as far as Afghanistan, Germany and London came to Greenwood Cemetery in the Mount Hope area to remember 68-year-old Mir Sadat Sahou, who was described as a man with outspoken political views.

Some people told 10News they believe Sahou may have been targeted for his political views.

Sahou's nephew, Mir Sadat, told 10News he hopes "the people who have done it ... that their conscience bothers them. I hope they don't sleep at night."

Late Wednesday night, police said Sahou was driving his cab along the 8600 block of La Jolla Scenic Drive before the shooting took place. Witnesses told police they saw Sahou arguing with a passenger outside of the car and then the passenger opened fire.

Police said the shooter sped away in the cab, leaving Sahou to die on the sidewalk. The taxi was found less than four miles away on Coast Boulevard.

10News learned one theory behind Sahou's death was his strong feelings about the injustices in his native Afghanistan.

Sahou, a former governor of the country's central bank, was granted political asylum 20 years ago and escaped the Taliban with his family.

He bought a taxi and started a new life in America, but he also never forgot his people and dedicated his life to helping his native country.

One family friend said, "He was very outspoken. I think [a] racial issue is involved."

Sahou bought airtime on public access and hosted a weekly TV show, and on the show he criticized the politics of Afghanistan and offered his solutions for change.

San Diego police have requested a copy of Sahou's show.

Mir Sadat said his uncle would never risk his life over a robbery and found it suspicious that his uncle's wallet and ring were left in the cab on the night of the shooting.

"I hope it is random because the pain will be much worse if it is something else," said Sadat.

San Diego police said their investigation into the shooting is ongoing.

A candlelight vigil will be held on Tuesday in La Jolla at the site where Sahou died.
