A few weeks ago, not long before Saturday's 20-year anniversary of the 9/11 terror attacks, Mariah Jacobsen got a tattoo on her left foot.
"Do something," it reads.
The words are inspiration from a man she never met, from someone she never knew until several years after he had died in the attacks, when, at 19, Jacobsen got her birth certificate from the Minnesota Department of Health and learned the identity of her biological father — Thomas Edward Burnett Jr., of Bloomington.
When Jacobsen, who had been adopted, read those words, she thought back to that September morning in 2001, when, as a junior at St. Paul's Cretin-Derham Hall High School, she saw news of the attacks and had the inescapable feeling she'd lost someone close to her.
"I cannot explain it, not in any way," she said this week. "I just had this knowing."
The discovery of her birth father's identity — that Burnett had been one of the heroes who charged the cockpit on United Airlines Flight 93, fought the hijackers and steered the plane into a Pennsylvania farm field instead of a Washington, D.C., landmark — would change her life.
On Saturday, during a 9/11 remembrance ceremony on the Minnesota State Capitol Mall, she'll tell of how the Sept. 11, 2001, attacks affected her and of the life lessons she's learned from Burnett's inspirational story.
"I felt lost for a while there," said Jacobsen, now 36, a Northfield attorney and mother of three. "How do I even begin to honor this man that I don't remember? But I've really learned lessons from my father and the passengers on United 93. Some of my father's last words to [his widow] Deena were, 'Don't worry, a group of us are go to do something.' "
