(ORANGE, Conn.) -- Connecticut police and the FBI are knocking on doors, combing the woods with dogs and searching by air for missing 12-year-old Isabella Oleschuk.
The Orange, Conn., girl was last seen Saturday night at her parents' home. Isabella is partially deaf and normally uses a hearing aid. Her hearing aid was left behind, prompting concerns among rescuers that she might not be able to hear people calling her name.
When ABC News reached Isabella's grandfather by phone, he said that the family is "anxiously awaiting her safe return."
Isabella's parents reported her missing early Sunday morning.
Police have issued a Silver Alert, which indicates that her disappearance is "mysterious" but not necessarily an abduction. Fliers being handed out throughout the town characterize the seventh-grader as an "endangered runaway."
Police have enlisted the help of the FBI, fire department and even police cadets to assemble a team of 100 that has fanned throughout the town of less than 14,000 people.
Isabella is described as five-feet, four-inches tall, 120 pounds with blue eyes and shoulder-length blond hair. She was last seen wearing a light blue jacket, brown-felt hooded cap and black rain boots.
