The night Zach left us will remain etched in my memory forever.   It began with the dogs’ frantic barking at 2 a.m., waking me from a restless sleep. I opened the Velux window to see a police officer standing outside.   "Mrs. Whittall, it’s the police," he said softly but firmly.   In that moment, my heart broke into a thousand pieces. I didn’t need to hear the words; I already knew. This was about Zachary.
