According to court documents Swift filed for divorce on October 10, 2011 due to irreconcilable differences.
"I think she's kept it pretty private and quiet out of respect for family, kids, and husband," Engelhardt said.
Friends said this is the second divorce for the couple, who still lives together. David Swift has until November 10 to respond to the petition for divorce.
Action News 5's attempts to contact David Swift were unsuccessful Thursday, but on Facebook, he told a friend, "We want her home and love her very much. Preston, my son has been speaking with the media. My main focus is to working with the authorities to get her home safely. Thanks for the many prayers and kind words which is greatly appreciated."
As authorities continue to search for clues in Swift's disappearance, friends like Engelhardt hoped for the best.
