The Barron County Sheriff's Department may have a lead in the case of missing 13-year-old Jayme Closs.

The Department shared three images on their Facebook page Monday afternoon, saying the photos are "images of the two vehicles of interest that we determined were in the area of the Closs home at the time of the incident."

They also reiterate the fact that as of now, these are only vehicles of interest. See the photos below:

You are asked to call the tip line if you have seen either of the vehicles in or around Barron County over the past two weeks. While leaving a tip, you should mention the time you observed the vehicle or vehicles, location you spotted it at and the plate number, if possible. The tip line is 1-855-744-3879.

The Barron County Sheriff's Department will not be looking into tips involving any other makes or models at this time.

On Monday, the Department also asked for 2,000 volunteers to help with "conducting an expanded routine search for articles of evidentiary value that may be related to the incident."

Just over a week ago, an Amber Alert was issued for the missing teen after her parents were found dead in their home.
