 One of the original investigators, Andre Edwards, told "Columbus Monthly" that after extensive review of the camera footage at the Ugly Tuna from the night Brian disappeared, which was intended to rule out the idea that Brian could have left in disguise, he could "say with 100-percent certainty" that Brian did not leave via the escalator.Police say they have three theories about the case but declined to discuss them even generally with the magazine.Between Brian's disappearance and his own death, Randy Shaffer joined the families of other missing adults in Ohio in lobbying the state legislature to pass a bill establishing a statewide protocol for such cases.
