The mother of one of the men who was fatally shot by authorities as he was executing a terrorist attack in Texas over the weekend is speaking out.

The gunmen, who have been identified as Elton Simpson and Nadir Soofi, drove from Phoenix to Texas on Saturday to attack a drawing contest of the Prophet Mohammed. After they open fired outside of the provocative contest, they wounded a security guard before they were instantly shot and killed by police, reports CNN.

Sharon Soofi, 59, said that she was shocked to learn that her son, Nadir, was involved in a terror attack. According to her, Nadir was an all-American kid who grew up in privilege and caused little trouble. He was born in Texas to a Pakistani American engineer father and a Catholic nurse. He attended a prestigious private school in the Middle East before his parents separated, and he moved back to the U.S. with his mother. He then went on to study pre-med at a college in Utah and later opened several difference businesses.

Nadir was also the parent of a 9-year-old son, who lived with his ex-girlfriend.

"He was a good parent," Sharon Soofi told The Los Angeles Times. "He loved spending time with his son. For him to do this sort of thing and leave him behind, you know, I still can't figure it out. And never will, probably."

"He was outgoing, he was intelligent, he did well in school; he just had a normal American upbringing," she continued. "He lived in nice neighborhoods. ... He really wasn't denied anything. ... He even told me himself that he had a very good life that was provided for him by his parents."

Soofi's father, Azam Soofi, added that his son "lived a real privileged life all his life. He was a very humble, soft-spoken person. Never said no to me."
