On the morning of January 7, 2010, fifty-five-year-old Terry Joe Mabry was shot and killed at the ABB Power transformer plant in St. Louis, Missouri. Mabry was outside near the winding room during a shift change around 6:30 a.m. when a disgruntled colleague opened fire in the parking lot. Mabry was hit in the leg and became unable to walk. Two coworkers, Stephen Sharp II and Matt Elder, tried to carry him to safety across the lot but were forced to retreat when the shooter advanced and fired again. Witnesses reported the gunman then walked up to the injured Mabry and fired fatal shots to the head.

The assailant also killed two other employees, fifty-seven-year-old Carlton Carter and twenty-seven-year-old Cory Wilson, and wounded five more before being found dead inside an office at the plant from a single gunshot wound. Investigators later identified the shooter’s mounting paranoia and dissatisfaction with his employer as the primary motives described in the inquiry. Does anyone have information about Mabry’s work life or those final minutes that could add detail to the timeline?
