Authorities said Wilbanks purchased a bus ticket out of town a week in advance using an assumed name and cut her hair in an apparent effort to disguise her appearance. She subsequently invented a bogus tale of being abducted by a Hispanic man and a white woman.
Gwinnett County District Attorney Danny Porter said Wilbanks' disappearing act was not "just a spur-of-the-moment thing."
But none of this appears to have made any impact her fiancé, John Mason.
"Her cutting her hair and getting on a bus and riding out of here ain't none of Danny Porter's business," Mason said. "And that's not criminal as far as I'm concerned."
Mason is defending his fiancée's decision, and says he still wants to walk down the aisle with her. The guilt she is dealing with "has got to be consequence enough to me," Mason said in an interview with Fox News' "Hannity & Colmes" show.
It was Mason's first public statement since he learned on the morning of his wedding day that his intended had gotten cold feet.
"We would still welcome her back to the family," Mason's father Claude said Tuesday on CBS News' The Early Show.
"I just said, 'John, you just know what's best for you. We've tried to help you through this as best we can, and it's your decision to make," Claude Mason told co-anchor Harry Smith. "'And if you decide you still want to marry her, be happy. Go with what makes you happy.'"
Mason and his fiancée's father, Harris Wilbanks, who also appeared on the show, said the 32-year-old woman was working on releasing a written statement. "She just needs some space and some time," Mason said. "She just wants the whole world to know she's very, very sorry."
But, Carter Brank, an agent with the Georgia Bureau of Investigation, said the would-be bride "didn't come right out and apologize" when he interviewed her. But, "she was somewhat remorseful for what she had done," he said.
If Mason and family members are ready to forgive Wilbanks, authorities are still peeved. Officials are looking into the possibility of suing Wilbanks for the estimated $40,000 to $60,000 cost of searching for her.
"We feel a tad betrayed and some are very hurt about it," Mayor Shirley Lasseter said.
A decision on whether to sue Wilbanks will be made in the next several weeks, reports CBS News Correspondent Randall Pinkston.
District Attorney Danny Porter said Wilbanks could face a misdemeanor charge of false report of a crime or a felony charge of false statements. The misdemeanor carries a penalty of up to a year in jail; five years in prison is the maximum sentence for the felony.
Mason said he has given Wilbanks her ring back — she had left it at the house — and said they still planned to marry. She was wearing the engagement ring during questioning Monday, authorities said.
"Just because we haven't walked down the aisle, just because we haven't stood in front of 500 people and said our I Do's, my commitment before God to her was the day I bought that ring and put it on her finger, and I'm not backing down from that," Mason said.
At a press conference on Monday, Duluth Police Chief Randy Belcher provided a chronology for Wilbanks' disappearance. He said Wilbanks bought a Greyhound bus ticket to Austin, Texas, a week before running away April 26. That day, she had a taxi pick her up at the local library and take her to the bus terminal in Atlanta.
She never made it to Austin, instead getting off in Dallas and buying a ticket to Las Vegas. She spent some time there, mostly hanging out at the bus station, before going to Albuquerque, N.M., authorities said.
It was in Albuquerque that she called Mason and police from a pay phone, saying she had been kidnapped.
