The suspects, George Huggins, 24, and Althea Housley, 33, both Oakland residents, are in custody on suspicion of murder for the death of Jinghong Kang on July 18.
Kang, 45, was shot at about 11:30 p.m. in the 1900 block of Webster Street during an apparent robbery as he walked to his car with a female friend.
Housley was arrested at 2120 Curtis St. in Oakland at 11:50 a.m. on Saturday. She is scheduled to be arraigned at the Wiley W. Manuel Courthouse in Oakland at 2 p.m. today.
Huggins, who police said also spells his last name "Hugguins," was arrested at the same location at 2:35 p.m. on Monday. His arraignment is scheduled for Wednesday afternoon.
However, Alameda County Chief Deputy District Attorney Tom Rogers said he hasn't yet filed charges against Huggins and Housley because he is still waiting to get the Oakland Police Department's report on the case. He said prosecutors have to charge and arraign Housley before the end of the day today or release her from custody.
Prosecutors have until the end of Wednesday to charge and arraign Huggins.
On the night of the shooting, Kang had driven to downtown Oakland to have his teeth cleaned by his friend, a dental hygienist, in preparation for an interview at Google the next day.
The two were heading to Kang's rental car from the dental office when two suspects approached them and demanded money, police said. Both Kang and the woman were pushed to the ground, and the woman heard gunshots.
Homicide investigator Sgt. Mike Gantt said the woman heard Kang tell the suspects before he was shot that he only had $17.
Last Wednesday, police released video footage of the two suspects, a man and a woman, who were captured on a nearby surveillance camera. Housley was arrested after a caller saw the footage on the news and recognized her, police said.
Police said Housley has admitted to taking part in the robbery and murder.
