Frequently choking back tears, African-American computer technician Michael Shaw bid an emotional goodbye to his wife and 6-year-old son before making his morning commute Thursday, sources confirmed. I dont know when or if Ill see you guys next, so I just want you to know how much I love you, Shaw said, his voice breaking as he prepared to embark on the 25-minute trip, including a stop at a Dunkin Donuts drive-thru, from which he might not return. Kevin, you take care of Mommy. Whatever might happen before I get to the office, you have to be strong, okay? According to sources, Shaw then grabbed his briefcase and his car keys and took one last look over his shoulder before opening the front door and walking down the lawn to the driveway.
