October 17, 1991 -- that's when a Missoula teenager vanished in Deming, New Mexico, after using a pay phone at a gas station to talk to her mother.

Fast forward to 2021. On April 4, Jennifer Pentilla would have turned 48.

He just got back from New Mexico, where he retraced her footsteps.

In this Spotlight Montana, D’Ambrosio shares with us what he discovered in New Mexico and how he hopes officials will take another look at this case.
