Police said Russell Weller told them he may have hit the gas pedal instead of the brake Wednesday, hurling victims into the air as his car careened down a street closed to traffic.
``Mr. Weller and his family want to express their deepest sympathies to the victims and their families of the tragic accident earlier today,'' Weller family attorney Jim Bianco said in a statement Wednesday. ``This was an unintentional and unfortunate accident.''
Eight victims were pronounced dead at the scene and a ninth, a 50-year-old man, died later at a St. John's Hospital, spokeswoman Barbara Bishop said. Fourteen others were critically injured.
Weller was not arrested, but authorities were considering whether the case was ``manslaughter of some type'' and investigating whether he was qualified to drive, said Police Chief James T. Butts Jr.
``There may be some negligence as to his capacity to drive safely,'' Butts said, although he added that Weller, of Santa Monica, has a valid driver's license.
Weller was taken to a hospital for a blood test and initial results found no traces of alcohol or psychoactive drugs such as antidepressants and hallucinogens.
Mary Roney, who has lived two doors down from Weller and his wife for 30 years, said he has never had any trouble driving and she did not know of any health problems.
``A more careful, gentle, loving person you'll never find,'' said Roney, who described him as active in the community, including serving on a library board and tutoring students at Santa Monica High School.
Butts said he did not have an estimate of the car's speed. Witnesses said Weller's 1992 Buick was moving very fast down the three downtown blocks of Arizona Avenue that were closed for the street market.
``Sixty miles per hour and it wasn't slowing down. It was flying. And then people down, dead and everything,'' said David Lang, manager of a shoe store along the market route.
``I heard a car just hit, bang, bang, bang,'' said Mojgan Pour, 38. ``I heard people screaming. By the time I looked, I never even saw the car. I tried to help a man and he died while I was helping him.''
Weller left police headquarters by late afternoon. Walking unsteadily with a cane, he hugged and smiled at people who picked him up from the police station. He declined to comment to a reporter.
The market, which takes place Wednesdays and Saturdays, bisects oceanside Santa Monica's popular Third Street pedestrian promenade and is near the famous Santa Monica Pier. It draws thousands of shoppers and was slated to close just as the incident occurred at 2 p.m.
The nine dead _ five women, three men and a 3-year-old girl _ were not identified. Police said 20 to 30 people had moderate or light injuries. They were taken to four hospitals by a fleet of ambulances and rescue helicopters.
A witness, Bahram Manahedgi, 50, said one person was on the hood of the car when it finally came to rest after the incident. A woman's body was crushed beneath the vehicle.
Manahedgi said that when he went to pull the driver out, ``His eyes were open and he was alive. I said, 'Do you know what the hell you did?' He said, 'No.' I just opened the door, I pulled him out.''
A crowd gathered around the car and ``wanted to beat him up,'' Manahedgi said. ``I said, 'He's an old man, leave him alone.'''
