A Metairie family experienced something similar to what the world saw happen to Damar Hamlin Monday night. Nancy Barcia said she was watching the Bills game and knew exactly what was going on. "I saw Demar stand up, kind of stumble a bit, and just completely fall flat back ways. And when that happened, I looked at my husband and said, 'He’s in sudden cardiac arrest,'" Barcia said. Her 17-year-old son, Chad, died from cardiac arrest in 2005 while playing rugby. Watching Monday night's game brought back the memories.
