Melissa Gerson cradles her 9-month-old baby, Kayla, as rescuers reunite the two after an accident on I-275 Wednesday. Kayla was secured in a child safety seat when a semitrailer truck rammed into the back of this Honda, right, in a southbound lane of the interstate near the Armenia Avenue exit. The impact crumpled the car's rear, pinning the baby inside. Rescuers had to back the truck off the car before the baby could be removed. Gerson and Kayla escaped serious injury in the crash. The two are visiting from Colorado and were with Gerson's mother, Penny Bailey, when the accident occurred. The crash tied up traffic shortly after 1 p.m.
