WALNUT CREEK -- Police are asking for the public's help in finding two suspects who kidnapped a 57-year-old woman as she left work last week in the Shadelands Business Park, used her bank information to withdraw cash from ATMs and then left her in the Oakland hills.

Detectives released surveillance photos as well as a bank surveillance video of the suspects in a news conference Tuesday afternoon. Police believe the crime, which occurred about 7:30 p.m. Nov. 7 on the 300 block of North Wiget Lane, north of Mitchell Drive, was planned but that the victim was random.

"She was at the wrong place at the wrong time," said Lt. Steve Gorski of the Walnut Creek Police Department.

Police said the suspects, who the woman said went by the names "David" and "Aubrey," drove her around for about three to four hours, forcing her to give them her banking information as they attempted to withdraw cash from two or three banks in Walnut Creek.

"David" is described as a white male in his early to mid-20s, 5 feet, 11 inches tall, 185 to 190 pounds with broad shoulders and short, dark hair. He was wearing a light-colored T-shirt under a black zip-up colored shirt and blue or black jeans.

"Aubrey," who is the suspect that can be seen in surveillance photos and the surveillance video, is a white male in his early to mid-20s, 5 feet, 9 inches tall, 150 pounds with a slight build. He wore a mask below the nose, a black hooded sweatshirt and dark jeans.

Police are still unsure if the names the woman heard were the real names of the suspects.

The amount of money withdrawn and the names of the banks are not being released.

When the suspects finally abandoned the woman in her car in the Oakland hills, police said they believe a car with a loud muffler possibly followed or picked up the suspects and drove off.

The woman was able to free herself enough from her bindings to scream for help and make her way to a nearby residence, where the homeowner contacted Oakland police, Gorski said.

Police said the woman has since recovered from most of her injuries but did not elaborate on how she was hurt or what injuries she suffered, only that most of her injuries resulted from being bound and gagged.

Anyone with information is asked to call Walnut Creek police at 925-943-5868 or 925-943-5844.
