SAN FRANCISCO (KGO) -- San Francisco police hope new video will lead them to the person responsible for the deadly beating of an elderly artist.
Police released surveillance video of a man they say is a person of interest.
Officers say the attack was unprovoked and happened in the middle of the day at the busy intersection of Van Ness and Market.
On December 5, 74-year-old Stuart Jackson was waiting for a bus when police say a man punched him so hard he fell to the ground and hit his head.
He died a week later. His dead has left a void in the community.
"I'm still in shock over Stuart's death. Everybody I talk to, we're just sickened about what happened to him," San Francisco resident Richard Weinberger said.
If you recognize the person in the video, please call San Francisco police.
