He used the killing curse.
Lord Voldemort killed Alastor Moody because he was helping to transport Harry Potter to the Burrow. To make it harder for Voldemort to capture Harry, six people took Polyjuice potion with Harry's hair in it - which meant there were seven Harry Potter's and the Death Eaters and Voldemort wouldn't know which was the real one. Each of the Potter's would fly with an adult guard to a safe house and would take a portkey to the Burrow. When they took off the Death Eaters attacked and Voldemort thought that the real Harry would be with the most experienced Auror so he went for Moody and his Harry, who was really Mundungus Fletcher. Mundungus was reluctant to take part in the plan anyway and as a killing curse was sent towards him he disapparated, the curse then hit Moody.
Moody was killed during a battle with Death Eaters. Voldemort killed him personally while moving Harry from the Dursley's house. He was aiming for the Mundungus, who was disguised as Harry beside Moody, but Mundungus disapparated and the curse hit Moody instead. This happened in The Deathly Hallows, Chapter 5, The Fallen Warrior.He died in the diversion the Order of the Phoenix created. One of the Death Eaters killed him. (7th book, Deathly Hallows)
