From Halopedia, the Halo wiki
Rowan Daoud was married to Sedran nurse Laura Daoud, and helped father two daughters, Sara Daoud and Nadia Daoud. He and Laura competed against each other to complete crossword puzzles without looking up the answers.
On February 7, 2556, his wife sent a message reminding him to pick up Nadia and Sara after school. The message was received sometime in between 0918 and 0955 hours due to large amounts of communications traffic as a result of the terrorist attack. He replied to his wife's message at 0955 hours while dropping the kids of to school, at that point Laura had sent three more messages detailing the dire situation at the hospital.
Later that day (presumably after receiving Laura's messages), Rowan was confronted by SER operative Ader Haddak while making his way to Saidia Elementary to make sure his children were okay. After a brief argument and the realization that Rowan was contaminated with the virus, Rowan was taken to Contamination Reduction Zone Guia by force. Rowan later died fourteen hours later on February 8, 2556.
