Who Is Evan Dooley?

"Really the thing I remember most about Brent is that he was always smiling," Whitehead said. "He always had a great sense of humor, he cared about how other people were doing. He was just as very friendly."

Today, Dooley lives in Olive Branch, Miss., a growing suburb. He has at least one child, friends said, and is a committed family man who is involved in his church.

He's "the guy next door," said Whitehead, a partner at a Memphis financial firm, who still occasionally meets Dooley for breakfast.

"I don't know how it happened, but I can assure you that in the worst case, it's a mistake," Whitehead said. "I don't think in any way Brent Dooley would ever be deceitful."
