The shooting took place around 2.30am on Tuesday morning at the Mueller Co plant in Albertville in the northeastern part of the state, WAAY reported.
Albertville Police Chief Jamie Smith said the shooter was an employee at the plant, but that the reason behind the shooting was “unknown”.
During a press conference later in the day, Chief Smith identified the shooter as Andreas Horton. He said Michael Dobbins and David Lee Horton were shot and killed at the Mueller Water Products plant.
The shooter was found dead along with his vehicle and multiple weapons just before 6am in Guntersville, about 26 miles northwest of where the shooting took place.
The company released this statement: “Mueller Water Products is shocked and deeply saddened by the horrific tragedy that occurred early this morning at our Albertville, AL, facility.
“Our hearts are with the victims and their loved ones, the Albertville community and the entire Mueller family during this extremely difficult time. Our entire focus is on the health and wellbeing of our colleagues, and we are committed to providing any and all support to them and their families.
“We continue to work closely with law enforcement, with whom we share our deepest gratitude for their support.”
Horton reportedly fled in a vehicle after the shooting and was not found until hours later.
The plant of Mueller Co is situated in an industrial park that houses a number of other companies, close to the city limits of Boaz and Albertville.
Police said earlier that other businesses in the surrounding area “are safe to conduct business as normal” and that “there is no danger to the public”.
Those who were injured were initially taken to Marshall Medical Center South in Boaz. Their conditions were not immediately made clear.
