Sam Singer

Sam Singer was the father of Kyle Singer and the husband of Helen Singer. He lost his job, which was why Kyle snuck the coke into the country. Sam was upset that Kyle had paid the rent because he wanted to care for his family. When Sam found out, he tried to stop him, but he tore the bag open instead. CTU thought this released the virus, but luckily it was part of a sting operation by Jack Bauer, Gael Ortega, and Tony Almeida.
