On June 15, 2021, a workplace shooting at the Mueller Co. plant in Albertville, Alabama, ended the life of 44-year-old employee David Lee Horton. The attack occurred around 2:30 a.m.; another employee, Michael Lee Dobbins, was also killed and two others were wounded. Authorities described the attack as apparently unprovoked.

Police identified the shooter as 34-year-old Andreas Deon Horton, a fellow plant employee. He fled the scene but was found a few hours later in a vehicle in Guntersville, about 15 miles from the Mueller Co. facility, dead of an apparent self-inflicted gunshot wound. Officials said there was no known familial relationship between Andreas Deon Horton and David Lee Horton.

Friends and colleagues remembered David Lee Horton as kind. The motive remained unclear as investigators continued their work. If anyone knew David, his routine at the plant, or saw anything relevant that night, please share what might help the inquiry.
