Jayme Closs's aunt: 'We will never stop looking for you'

Showing signs of strain and heartbreak, the aunt of missing Barron teen Jayme Closs promised to never give up hope of finding her 13-year-old niece.

"To whoever may know where Jayme is, please contact the Barron County Sheriff's Department. Jayme, we need you here with us to fill that hole we have in our hearts. We all love you to the moon and back and we will never stop looking for you," Jennifer Smith said during a news conference held by the FBI and Barron County Sheriff's Office.

"Your dog Molly is waiting for you. She is sleeping in one of your sweatshirts. Grandpa needs new artwork on his fridge," Smith said. "I want that girl's shopping date we planned."

Jayme has been missing since the early morning hours of Oct. 15. Investigators believe she was abducted after her parents, James and Denise, were shot to death in their Barron home.

On Wednesday, the FBI announced a $25,000 reward for information leading to the location of Jayme Closs.

Sheriff Chris Fitzgerald has identified two vehicles of interest that were captured on home and business surveillance video near the Closs home around the time of the incident.

One vehicle is believed to be a 2008-2014 Dodge Challenger that's red or orange in color.

The second vehicle is black in color. The sheriff says it is believed to be either a 2006-2010 Ford Edge or a 2004-2010 Acura MDX.

People who have information on these vehicles or spot them are urged to take down the time, location and license plate and call the Jayme Closs tip line at 1-855-744-3879.

"There's a lot of tips coming in on the vehicles. The last uptick in tips has been due to those vehicles," Fitzgerald says.

On Tuesday, 2,000 people searched a large area along Highway 25 for possible clues.

Sheriff Fitzgerald says nothing of evidentiary value has been found to date, but investigators are still analyzing items.

The gun used to shoot James and Denise Closs has not been recovered.

Investigators have received about 1,740 tips. They've closed out more than 1,400 of those tips.

"We believe Jayme's out there, Jayme's endangered, and we need to bring a 13-year-old girl home, Fitzgerald said.

The sheriff wants anyone who was driving in the area at the time of the crime to call the tip line.

"We're looking for anyone who was on Highway 8 on that early Monday morning from 12:30 to 1:30 to help with that investigation. You're not a suspect. You may have seen something on the side of the road that you don't realize you've seen," Fitzgerald says.

Jayme's aunt, Jennifer Smith, just wants her niece to come home.

"Jayme, not a moment goes by when we aren't thinking about you or praying for you," Smith says.
