NASHVILLE, Tenn. -- Country singer Whitney Duncan is on a roll. After traveling the globe on the CBS reality show The Amazing Race,  Duncan released the new single "Roll All Night." She also married her 'Amazing Race' teammate, Keith Tollefson, this year.

"I was so stressed out about that I think planning a wedding is almost as stressful as The Amazing Race," Duncan said.

But she said it was a good distraction from the others things she wasn't ready to deal with in her life.

"Yeah, ups and down throughout the whole tragedy with Holly. It's just been a rough year," Duncan said.

In March,  Zach Adams was arrested and charged with the kidnapping and murder of her cousin Holly, and in September, the nursing student's remains were found in Northern Decatur County.

"It's just something still so bad it's hard to even grasp. Who could do something like that to someone you love?" Duncan said.

Holly Bobo disappeared from her home in Darden, Tennessee, in April of 2011.

Jason Autry was also charged with her murder and kidnapping. Dylan Adams, Zach Adam's brother, was charged with rape. A fourth man, Jeff Pearcy, is facing a charge of  tampering with evidence.

Duncan can't talk about the case or people involved, but says right now she just wants justice for Holly.

"I'll be there when it matters most. It's really hard. It's going to be really hard, I think, to hear some of the details. That's not what I want to think about or know,  but I'll be there to support my family, and for Holly," Duncan said.

Duncan says all the support the family is getting from the community is also helping.
