Murder of sibling changes demeanor of victim’s brother

DEAR ABBY: Last year, my son, his girlfriend and two others were murdered outside a city where “things like this don’t happen.” My other two boys received a call to come immediately to their dad’s home, where it had happened. My boys were the first to witness the bloody scene. They called 911. My son lived two days more. Today would have been his birthday. His brothers witnessed something beyond imaginable.
