(CNN) Tennessee authorities are looking for a 15-month-old who was last seen two months ago and the reward for her safe return has reached $33,000.

An Amber Alert was issued for Evelyn Mae Boswell who was reported missing this week. But according to the Tennessee Bureau of Investigation (TBI), she was last seen on December 26.

The TBI believed people who were traveling in a gray 2007 BMW had information about the girl's whereabouts, the agency said.

Authorities located the car and the people in Wilkes County, North Carolina, late Friday. It's unclear how the people were connected to the missing girl.

Evelyn remains missing and no one has been charged in connection with her disappearance, the agency told CNN.
