Friday is Phuong Le's 25th birthday but instead of a celebration, her family is planning a candlelight vigil.
The Suisun City woman was last seen Sunday at a bookstore in Fairfield. Her family says she left without telling them where she was going. Police found her car unlocked with the windows down, her backpack and wallet locked in the trunk.
It's unclear whether Le disappeared on he own or whether she was kidnapped. Police are investigating both possibilities.
Le is 5 feet 3 inches tall, weighs about 105 pounds and has black hair and brown eyes. Fairfield police have set up a tip line for information in her disappearance: 707-428-7345.
