On Dec. 9 friends and family of community activist David Lewis gathered at the spot where he was shot and killed to mark the six month anniversary of his death. They begged his killer to come forward and for people with information about the case to end their silence and talk to police.
Just two weeks later, San Mateo police made an arrest in the unsolved homicide. On Sunday, investigators arrested Gregory Elarms of Pittsburg. They said the two knew each other, but would not give a motive. Police said Elarms acted alone when he followed Lewis to the mall and shot him.
Lewis was killed by a single bullet in the parking lot of the Hillsdale mall on June 9. He was a community leader in East Palo Alto who co-founded a substance abuse treatment center called Free at Last.
San Mateo Police Chief Susan Manheimer credited her investigators for keeping the case alive and not giving up on finding Lewis' killer.
The chief would not say what cracked the case and would not say if anyone is now a candidate to recieve part of the $50,000 reward.
