SEASIDE, California (CNN) -- Hundreds of FBI agents, sheriff's deputies and armed forces personnel searched in the Monterey area on Saturday for a 13-year-old girl who disappeared on June 12.

Investigators are pursuing reports of two men seen in a car near where Christina Williams was last seen walking her dog near her family's home in Seaside.

Officials released a sketch of the car's driver Friday, two days after circulating a drawing of the car's passenger based on a description from a jogger who was harassed by the men the night Christina was abducted.

According to that account, one of the men turned to the other and indicated that the woman wasn't the type they were looking for. The men then drove away.

Police have received more than 200 calls since releasing the first sketch, most of them with information regarding the men in the car.
