BARRON, Wis. (CNN) - Jayme Closs' family says they are resolved to bring her home.
It's now been more than a month since anyone has seen the 13-year-old.
Authorities believe the girl was abducted from her home in Barron County after her parents were shot and killed on October 15.
Jayme's aunt and godmother, Jennifer Smith, says her life has been turned upside-down since her sister Denise and brother-in-law James were found dead and her niece disappeared.
"I keep thinking maybe it's targeted, 'cuz what else? I can't come up with anything else. As much as my mind keeps going and trying to think of something, I can't. Why this would ever happen?" Smith said.
Just hours before the murders, Jayme and Denise were at Smith's home to celebrate a family birthday.
The family is determined they will see Jayme again.
"We will not give up to bring that girl home. We love her more than anything," Smith said.
There is a $50,000 reward for information that helps investigators find Jayme.
Earlier this week, Barron County Sheriff Chris Fitzgerald said investigators cleared more than 2,300 tips, and the FBI was expanding the collection of surveillance videos after reviewing more than 80 videos from security cameras at homes and businesses near the home.
