Aldenberg said at a press conference on Monday updating the investigation a special phone line was established at 603-203-6060 that will be manned 24/7 to take information and tips about Harmony Montgomery.

"I can not emphasize enough how important any and all tips are. Even if you believe you saw this little girl a year ago or two years ago please call in. Knowing where she was can help narrow down where she is now," Aldenberg said.

Anonymous Massachusetts businessman from Lynn and Newton added $10,500 to the reward for information leading to finding Harmony. The reward now stands at $33,000.

Montgomery is described as approximately 4 feet and 50 pounds with blonde hair, blue eyes and glasses. She is blind in her right eye.
