HAYWARD -- Prosecutors have charged a four-time drunken driver with the death of a passenger who was fatally shot by police during a chase in downtown Hayward last month.

Arthur Pakman, 23, of Oakley, has been jailed since the March 3 traffic stop and subsequent police chase that culminated in the death of his friend, 19-year-old Shawn Joseph Jetmore Stoddard-Nunez of Hayward.

Police said that shortly before the fatal shooting, Pakman was drunk and defied orders during a traffic stop, ramming his 1988 Honda Civic into a police cruiser and nearly hitting a civilian riding along with police. The officer fired at the car, striking Stoddard-Nunez twice. Police said he was an unintended victim of the shooting.

Court papers show Pakman has been charged with murder, assault with a deadly weapon and driving while intoxicated with a blood-alcohol level of 0.15 or higher. Records also show he has four DUI convictions in Contra Costa County -- one from 2010 and three from 2008.

Pakman was arrested at 3:20 a.m. March 3, when he finally surrendered after fleeing the shooting scene at Fletcher Lane and Watkins Street and crashing at D Street and Foothill Boulevard.

Following the crash, Pakman submitted to a blood test, police said. Results of the test revealed his blood-alcohol level was 0.23 -- nearly three times the legal limit to drive, Sgt. Eric Krimm said.

Police have said that if Stoddard-Nunez had lived, he likely would not have been charged with a crime in connection with the chase.

Family and friends say that on the night of his death, Stoddard-Nunez asked Pakman for a ride to another friend's house early Sunday after a night of drinking.

Friends called Stoddard-Nunez a "sweet person" with a gentle smile. Pakman met Stoddard-Nunez while he was living in Pinole and attending Pinole Valley High School, said his foster mother, Loretta Hale.

At 14, Stoddard-Nunez came to live with Hale in Pinole after bouncing between foster homes throughout California. He and his brother were moved into a group home in 2011 after they were the victims of a home invasion perpetrated by their friends, according to Hale. Recently, Stoddard-Nunez was attending Laney College and had aspirations to be a chef.

Pakman had been jailed without bail in Contra Costa County for a parole violation stemming from his latest 2010 DUI convictions in connection to his March 3 arrest.

His Hayward-based attorney, Frederick Remer, has said his client was on his way to visit his girlfriend in Richmond on the morning of the incident and never intended to strike the police car.
