Miraculously, the baby survived and suffered only some gashes on her leg and cuts on her head. But her mother says the normally playful and happy 9-month-old has seemed troubled ever since the incident at a McDonald's restaurant drive-through.

It all began a few days ago when Jenifer Pisano was walking her baby, Sofia, in the stroller along a Ballard street. As they were in a crosswalk, a young male driver in a white Honda CRX nearly ran them down as he drove past.

She walked over to the McDonald's to confront the driver about nearly hitting her, pushing the stroller ahead of her.

As she stood in front of his car in the narrow drive-through lane, Pisano spotted an open beer can in the vehicle and threatened to call 911.

That's when the driver seemed to lose it.

"He just put his car into neutral and revved the engine, and then bumped her stroller a couple of times," Pisano says.

The stroller was pushed ahead along the drive-through, with the baby girl inside, then the driver gunned it and ran over the stroller, spinning his tires.

Mechanics at a shop next door looked over in horror and couldn't believe what they were seeing.

"I saw the stroller being pushed under the car for maybe 10 feet, then under the tires. Heard the plastic crunching," says one of the mechanics, Bradyn Lyon, describing the incident.

Another mechanic, Collin Baroh, describes what happened next.

"His tires spun. It pretty much spit the stroller out and grinded up on the rail," he said.

The Jeep stroller's steel tubing snapped, and the frame collapsed. But the stroller's heavy-duty construction likely saved the baby girl's life.

Pisano ran to her baby, convinced that Sofia was probably dead. And she still remembers the huge relief she felt at find her baby still alive.

"I just can't believe she's here," Pisano says.

The mechanics who witnessed the incident said it was obvious that the teen driver knew the baby stroller was there when he ran over it and fled.

"There's no way he didn't know the stroller was there," Lyon said.

Pisano says, in retrospect, that it probably was not prudent to walk in front of the car with the stroller.

"I feel just absolutely stupid for doing it now, but the mother bear in me, I guess, came out," she said.

Although Sofia survived, she hasn't been the same since the incident, her mother said.

"I mean, I don't know if 9-month-olds have nightmares, but that's what it seems like to me," Pisano says.

She was able to get a partial license number of the car, and detectives have a fair amount of evidence to track him down.

If he's caught, he could face a charge of attempted homicide, police said.
