I don't recall those incidents from the book (American Sniper), either. I did find this via Google:I guess I need to read the book again because I don't recall him claiming to have shot people from the super dome. Nor do I remember him claiming that he shot two carjackers at a gas station. I heard the story, but not from Kyle himself.
Was there ever an interview where he made these claims himself, or were these stories generated by others?
According to several reports published after his death, Kyle told a story about shooting two men who tried to carjack his truck not long after he left military service. As the story goes, police investigating the incident were directed to a phone number at the Department of Defense, where they were apparently told of Kyle’s military background and accomplishments as a sniper.
But the carjacking story could not be independently confirmed by various publications, including The New Yorker in its latest issue. Asked about the carjacking story, Taya said, “All I can say in response to that is that people enjoy taking rumors and try to paint a picture of what they want it to be.”
Taya said she couldn’t recall ever hearing Chris tell the carjacking story publicly. Asked if he had ever told her the story, she said, “I’ve been sticking to what he decided to share publicly and only share those things.”
She added: “I can tell you Chris was as honest as the day is long.”

Plenty of reports of people being told this story by friends and acquaintances of Kyle, but nothing to confirm that Kyle himself ever told it the way it was reported.
