Anton Lundin Pettersson

Anton Niclas Lundin Pettersson was a Swedish mass murderer who was responsible for the Trollhättan School Massacre on October 22, 2015. It is the deadliest school massacre in Swedish history.

Background
Pettersson was born on June 22, 1994.

Stabbing
Sometime before the massacre, Pettersson purchased a German World War II helmet and a sword, the former of which he painted black. He applied white makeup and black eyeliner to his face, then put on a black trench coat, black boots, and a black face mask which resembled that of the Star Wars character Darth Vader. After seeing his brother one last time on Facebook and sending a private goodbye message to one of his online gaming friends, he took his father's car and drove over to his brother's house. Pettersson placed his remaining money on the kitchen table before driving over to Kronan School.

Pettersson entered the school through a side door and quoted one of Darth Vader's most famous lines: "I am your father." (He reportedly said this multiple times during his attack.) He approached teaching assistant Lavin Eskandar and killed him by cutting him diagonally across the head before stabbing him twice in the back. Eyewitnesses initially believed that the attack was just a Halloween prank. A woman activated the school's emergency alarm while Pettersson searched for more victims. Two minutes later, the assistant principal called the police.

While the principal and his colleagues ran around the school warning staff and students about the rampage, Pettersson played a remix of Rob Zombie's "Dragula" on his mobile phone. After bumping into several locked doors, he went up the stairs to the second floor. He then stabbed Ahmed Hassan in the abdomen, who proceeded to stagger down the stairs and fall to the floor. Three students noticed Pettersson and, still believing it to be a prank, asked if they could take a picture with him. Since they were all white, he made no attempt to harm them and granted their request without saying anything. The infamous photo depicts him posing with two of the students while the third takes the picture. The blood from his previous victims can be seen dripping from his sword. Moments later, teacher Nazir Amso approached them and, deeming Pettersson's outfit to be inappropriate for school, demanded to know his identity. He was stabbed in the abdomen, and he and the three students realized that the event was completely serious. As Amso fled, Pettersson chased after him, but stopped when his victim managed to escape the building.

Pettersson matched back to the second floor and knocked on a door to one of the classrooms. Wahed Kosa opened it and asked, "Who are you?" After staring at the student for about 20 seconds, he stabbed him in the stomach. Amazingly, Kosa was able to close and lock the door despite the severity of his injuries. His classmates saw the blood oozing from his body and assumed that it was a prank, some even jokingly yelling, "Now it is war!" He escaped from the room and fell down a teacher's lounge where educators then tried to stop his blood flow.

About ten minutes after the rampage had begun, two police officers arrived at the school and almost immediately spotted Pettersson patrolling the second floor. When they told him to stop his weapon, he raised his sword and charged towards them; he was consequently shot in the abdomen. Upon being placed in handcuffs and unmasked, he told the police his name. Pettersson and three of his victims were rushed to the hospital, where he later died.

Aftermath
Pettersson's rampage initially resulted in one death and three injuries. Eskandar was the only one to have died in the building, but Hassan then died the same day in the hospital. On December 3, Amso died in the hospital as well, leaving Kosa as the only surviving victim.
