ALBERTVILLE, Ala. — The Albertville community continues to be in shock after a deadly shooting at the Mueller manufacturing plant Tuesday morning.

According to Albertville Police (APD), two people, Michael Lee Dobbins and David Lee Horton, were killed with two others, Casey Sampson and Isaac Byrd, critically injured and transported to the hospital after being shot by Andreas “Andy” Horton.

The gunman was found dead several hours later in Guntersville from a self-inflicted gunshot wound. No motive has been confirmed for the deadly attack.

Michael Lee Dobbins has been described by friends and family as a loving husband to his wife Amanda and a great father to his daughter, Daisy. Friends of the Dobbins family have set up a GoFundMe to help with funeral expenses that can be found here.
