Update (11:54pm 01/03): KNTV is now reporting that the girl has been found safe and the suspect is now in custody.
An Amber Alert has since been canceled for 7-year-old Natalie Calvo out of a San Francisco, California suburb.
Police said the 7-year-old girl was abducted from her Antioch, California home at 6:45 p.m. Friday. The alleged kidnapper spotted the family at a Walmart and followed them to their home about six miles away, according to police.
The suspect then jumped out of his car and took Natalie from her mother, police said.
Natalie is described as a Filipino girl, 3 feet tall, 54 pounds, black hair and brown eyes. She was last seen wearing a neon pink scarf and jacket, gray leggings (jeans style), brown boots and with her hair in a ponytail.
The suspect is an unknown Asian male, about 40-50 years old and possibly armed with a black, long gun, police said. He was last seen driving a 1990s gold, four-door Toyota Camry leaving Natalie's home.
Anyone with information is asked to call Oregon State Police at (541) 776-6111 or dial 911.
