1-Year-Old Recovering After Day Care Car Crash in Billerica, Mass.

A 1-year-old boy who was pinned under a car that crashed into a day care center in Billerica, Massachusetts, is recovering Friday.

Billerica Police say a driver having a medical episode struck several cars and crashed through the wall of a daycare center, pinning a toddler beneath her vehicle.

Deputy Police Chief Roy Frost says an SUV driven by a 38-year-old Billerica woman slammed into A Brighter Rainbow Learning Center around 5:30 p.m. Thursday.

"I saw her car catch air, it came off the ground and landed and she still was slumped over," said Mark Chen, who was nearly hit by the car.

New surveillance video shows the Subaru Outback careening down Boston Road in Billerica just moments before it crashed into this daycare, pinning the young boy beneath it.

"I heard first a big bang and then I saw a lady hit a car and then there's a berm, she hit a berm and she caught air and then she bounced off a telephone pole and she was headed right for me," said Chen.

Chen says he was pulling his pickup truck out of the parking lot when he realized the driver of the Subaru was not right.

"She was just slumped over," said Chen, "she had no hands on the steering wheel, she wasn't awake she was passed out, I don't know what happened."

Chen says he watched in horror as the car bounced off this fence, tore across this lawn, and jumped these rocks before smashing into the daycare.

"There was someone screaming, he's under there, he's under there!" said neighbor Mike Madigan.

Madigan rushed over to help, spotting the 22-month-old boy wedged under the car with blocks, glass and toys.

"I didn't know if he was stuck under there or whatever, so I crawled underneath and got right up to his face and tried to make sure that nothing was pinning him in," said Madigan, "so I just grabbed him by his shoulders and was able to drag him out."

Madigan says as a parent himself, it was a nightmare situation, but he was thrilled the injuries weren't worse.

"He was pretty hysterical, he had glass on his face and I just tried to comfort him," said Madigan, "I'm just still amazed with all the debris and everything around him, he just walked away with glass on his face."

Police said the child appeared to have mostly suffered facial injuries and is expected to be released from Tufts Friday or Saturday.

Doctors were trying to determine what type of medical episode the 38-year-old Billerica woman driving the car had before the crash.

Officials say the building is not structurally sound after the crash.

The crash remains under investigation.
