Hannah didn't speak publicly before entering the building, though her father later did talk to reporters. The media were invited to the fundraiser at the family-friendly restaurant, but were not allowed inside.
"This is a small community that we are a part of, and the community came together putting on this great fundraiser for Hannah and hopefully for her future and healing," Brett Anderson said, before he thanked local residents, family and friends, the media and law enforcement. "This is how Lakeside rolls."
Speaking Thursday about her condition, Brett Anderson said "she's just happy to be here."
"Hannah sends her love," her father said. "She's doing good day by day, and we'll keep moving forward from here."
One of her friends, Alyssa Haugum, said from outside Thursday's fundraiser that she was looking forward to seeing Hannah and giving her a hug. They had communicated via Facebook, she said.
Haugum described Hannah, whom she knows from school and dance, as strong, funny and "usually really bubbly."
"It takes a lot to make her upset," she said of her friend.
The entire ordeal was surreal and scary, as it hit so close to home, Haugum said.
"It just felt like it was untrue: One day somebody could be with you, and the next day they are missing and you don't know where they're at," Haugum said.
Then, alluding to her friend Hannah, she added, "But I knew she was strong. I knew she would come back."
