The parents of a missing 12-year-old Silver Spring girl spent Friday hanging up flyers in the District's Columbia Heights neighborhood, hoping to re-establish contact with their daughter after more than four days.

Tania Carolina Molina-Raudales was last seen about 7:15 a.m. Monday as she left her family's home headed for her bust stop at Northampton Drive and Beacon Road in Silver Spring.

But Molina-Raudales never made it to White Oak Middle School. She was spotted near the bus stop, getting into a car driven by a Hispanic man, police said. The girl has not attended school or contacted her family since.

"I don't know how to explain to you what I feel -- I feel very, very bad," said the girl's father, Ricardo Hernandez. "We're scared and very worried."

Molina-Raudales has not run away from home in the past, police said. And family members say she had no reason to run away.

"This girl is very good, plays in the house, goes to school and come back and I don't know what's going on," said Ronald Brown, a family friend.

Investigators suspect Tania knew the man in the car. They say there is no evidence of foul play, but there is concern for her welfare.

"She's a 12-year-old little girl and the longer she remains unaccounted for -- We don't know who she's with, what she's doing -- the more concern there is for her welfare," said Lucille Baur, Montgomery County (web|news) police spokesperson.

The girl is described as a Hispanic female, 5'5" tall, weighing 135 pounds with brown eyes and long black hair. She has three piercings in each ear. Molina Raudales may have been wearing a gray sweatshirt, blue jeans, and carrying a black purse or book bag.

She was seen getting into an older-model black four-door vehicle.

Anyone with information was asked to call the Family Crimes Division at 240-773-5400 or the Montgomery County Police non-emergency number at 301-279-8000.
