HINGHAM, Mass. (WHDH) -- A woman in Hingham is accused of taking a dangerous drive with a three year-old in the back seat of her car.

Police said Marcia Blake, 54, was high on painkillers when she crashed head-on into another car Friday. Blake had been babysitting the three year old, who was not hurt. Blake broke her knee when she crashed the Chrysler Sebring.

“It sounded like someone hitting the ignition on a gas grill when you leave the gas running too long…that thing just lit up,” said Brian Claffey.

Two cousins, both off-duty firefighters, saw the accident and the fire. They pulled over and rushed to pull Blake and her sister’s granddaughter to safety.

“Flames started coming around the hood so he and I had to bend the door open to get the woman out of the driver’s seat. So I was in front of them, so I just wrapped her up and picked her up and walked away,” said David Buckley.

“I looked at the kid and the car just started to fill up with the smoke. And the kid, who is three, was trying to get out and ended up making the situation worse, got her hands and her legs wrapped around the straps,” said Claffey.

Claffey an EMT, who happened to have his gear in his personal SUV, was able to get the girl out safely.

The 67-year-old woman driving the other vehicle, a Nissan Maxima, was seriously hurt and taken to the hospital.

Blake said she was not high on pills, but was distracted by the child who was trying to hand her a toy. But, police said she was being tracked on different streets by another driver who dialed 9-1-1.

“She was traveling all over the road, crossed over the center line several times. She stayed on the phone with us and gave us an updated location of where the car was going,” said Sgt. Steven Dearth, Hingham Police Dept.

The woman driving the Nissan is still hospitalized, but will survive. Blake was convicted in 1999 for driving under the influence. Now, she has five new charges, including child endangerment.
