Donna Gant sat reading a magazine on the couch in the family room of her center hall colonial. It was around one o'clock on an August afternoon, and the late-summer heat and humidity was swelling outside. Donna was enjoying her last "free" days before the new school year began, and she would have to get back to work. Donna was a science teacher at the local high school where here sons, Ryan and Mitchell, attended. She and her husband, Tom, had moved to the town some 12 years ago, when Ryan was just five and Mitchell was only two.
