It could be a big break in the case of a missing seven year old girl in Southern California. Police have arrested a suspect in the disappearance of Danielle van Dam.

They aren´t saying who it is but television footage showed David Westerfield a 49 year old neighbor being led away in handcuffs from his attorney´s office. Westerfield had been questioned several times in the disappearance of the San Diego area girl.

Danielle was last seen three weeks ago when her father put her to bed. Her parents spoke briefly to reporters this afternoon and said they´re pleased with the arrest but upset that their daughter is still missing.
