A couple Phoenix, Arizona driving to the hospital had no idea that their baby girl would arrive as soon as she did. When it became apparent that the baby would have to be delivered before reaching the delivery room, the couple called 911 and pulled off into a parking lot. The baby was delivered with the assistance of a police officer that responded to the 911 call. Ivy Cate Casteel, the new addition, weighed in at 10lbs 6oz.
