On July 17, 2017, 24-year-old Brianna Jayde Vibert was last seen in Flint Township.

Surveillance footage from a gas station shows her anxious—possibly panicked—with visible injuries to her arm. In the early morning hours, she accepted a ride from a man in a red Pontiac Aztek. Over the next few hours, she would appear at multiple locations—disoriented, unsteady, and clearly in distress.

Then, she vanished.

Her phone was left behind. Her purse was later found in a ditch near her home. And Brianna—who was a mother of four—has never been heard from again.

In this episode of The Lost Girls, Amy Smith and LaDonna Humphrey walk through the final known hours of Brianna’s life, the people she encountered, and the troubling gaps that remain. They also examine the circumstances surrounding her relationships, her past, and the question that still lingers:

Was Brianna Jayde Vibert running from something—or did she cross paths with someone she couldn’t escape?

Her story didn’t end that night.

It simply disappeared.
