HOBOKEN, New Jersey (WPVI) -- After receiving numerous reports of a baby left inside of a locked vehicle alone, medics in Hoboken, New Jersey broke the driver's side window of the vehicle to rescue the apparently lifeless looking child.After gaining entry to the car, the EMTs discovered the reason the baby seemed lifeless was because it was a doll belonging to the granddaughter of the owner of the car.While this turned out to be a false alarm, police say they are very serious about rescuing children left alone in cars.There have been numerous incidents this summer. Earlier this month , relatives said a 3-year-old South Carolina boy died several days after being trapped in a hot car. They say he had climbed into the vehicle while his mother slept. Last week , police told Action News a 6-week-old baby was left unattended inside a SUV in the parking lot of a Northeast Philadelphia Walmart store.
