crazy and/or badass:
Howard Barton Unruh (January 21, 1921 - October 19, 2009) was an American spree killer who killed 13 people on September 6, 1949, in Camden, New Jersey, when he was 28 years old. Unruh is considered the first single-episode mass murderer in U.S. history.
He had trouble getting along with his neighbors, and his interactions with them deteriorated in the three months before his spree. [...] Eventually Unruh became paranoid about his neighbors and started to keep a diary detailing everything he thought was said about him. Next to some of the names was the word "retal.", short for "retaliate." He arrived home from a movie theater at 3 am on September 6 to discover that the gate he had just built in front of his house had been stolen. This appears to have been the trigger; Unruh told the police, "When I came home last night and found my gate had been stolen, I decided to kill them all."
After sleeping until 8 am he got up, dressed in his best suit and ate breakfast with his mother.
At 9:20 am, Unruh left the house armed with a German Luger pistol looking for his first victims. In only twelve minutes he shot and killed 13 people with 14 shots. Although in general the killing was premeditated, the victims seemed to be chosen at random. Unruh's first shot missed its intended victim, a bakery truck driver. Unruh shot two of five people in a barber shop, sparing the other three. One victim was killed when he happened to block the door to a pharmacy. A motorist was killed when his car slowed to view the body of a victim. Intending to kill a local tailor, Unruh entered his shop, but the tailor was not there; Unruh killed the man's wife.
Other intended victims successfully locked themselves inside their businesses (a tavern and a restaurant), and Unruh was unable to reach them.
When he heard the sirens of the approaching police, Unruh returned to his apartment and engaged in a standoff. Over 60 police surrounded Unruh's home, and a shootout ensued.
During the siege, Philip W. Buxton, a reporter from the Camden Evening Courier, phoned Unruh's home and spoke briefly with him. On a hunch, Buxton had looked up Unruh's number in the phone book. Buxton later recounted the conversation, which was cut short when police hurled tear gas into the apartment:
Buxton: "What are they doing to you?"
Unruh: "They haven't done anything to me yet, but I'm doing plenty to them."
Buxton: "How many have you killed?"
Unruh: "I don't know yet. I haven't counted them. But it looks like a pretty good score."
Buxton: "Why are you killing people?"
Unruh: "I don't know. I can't answer that yet. I'm too busy. I'll have to talk to you later. A couple of friends are coming to get me."
