This comes from the Arcadia Police Officers Association Blog:
The Arcadia City Council voted last night (Tuesday) to add an additional $20,000 reward in the robbery/murder case of Jason Wei. Jason was killed in November 2007 during a robbery at the Osaka Ya restaurant in Arcadia. This reward offer brings the total reward offer to $40,000. The Los Angeles County Board of Supervisors voted last week to offer a reward in the case.
