Maybe it's the Guns...

It was that gun loon heaven, Switzerland, that led the drive to ban absinthe after Jean Lanfray killed his family.  Maurice Zolotow, in a 1971 article, provides this account of the murders:

"On August 28 1905, Jean Lanfray, a vineyard worker and day laborer in the little village of Commugny, Switzerland, awoke at 4.30 in the morning. He began his day with his usual eye opener: a shot of absinthe, to which he added three parts of water. Before the day was over, Lanfray would commit a series of horrible murders and, ultimately, he would bring about the downfall of a $100,000,000 industry. Lanfray was a tough, burly peasant. He weighed 180 pounds. He was almost six feet tall and was in robust health. He was a Frenchman by birth He had served his three years of military service with the Chasseurs Alpins regiment of the French Army. There he had learned two things: how to kill and how to drink absinthe.

At that time, absinthe was the best-selling before-dinner drink in much of the civilized world. It was - and is - an anise-flavored liquor of high alcoholic strength, preferably 136 proof. It is made by steeping various herbs in neutral grape spirits for eight days  and then redistilling the concoction. Among the 15 herbs in absinthe are the dried flowers and leaves of wormwood, a plant that grows about three feet high and is botanically related to our South-Western sagebrush. The German word for wormwood is Wermut, or vermouth; there are small amounts of wormwood oil in vermouth. The Latin for wormwood is Artemisia absinthium, and its oil is known as absinthol, hence the name of this elixir. For many years, a considerable number of French physicians and biologists had regarded the wormwood plant as deadly poisonous.

On what was to be a most eventful day in the history of drinking, Lanfray, 31, got dressed . He lived with his wife and two children on the second floor of a farmhouse. His parents and his brother, Paul, lived downstairs. Lanfray had a second absinthe and water. He wiped his lips. He told his wife to wax his boots while he went about his chores, as he planned to go mushroom hunting in the woods the next morning. His wife grumbled something or other. During the past year, the couple had been constantly quarreling - about money, about her in-laws, about his drinking habits.

"Don't forget to wax my boots," Lanfray repeated. "And make it good, you hear?"

He went to the barn and watered the cows and let them out into the pasture. He returned and had some coffee and bread. The children - Rose, four and a half, and Blanche, one and a half  - were still asleep. Lanfray went downstairs. He joined his father and brother. The three Lanfrays then began walking to the vineyards near the village where they were employed. En route, they passed the local auberge and Jean, a man who could not go very long without slaking his awesome thirst, went in. It was about 5:30 A.M. (a Swiss law- enforcement official, as we shall see, compiled a meticulous record of Lanfrey's alcoholic intake that fatal day) and our man had, first, a creme de menthe with water, and then a cognac and soda. He worked until noon. He had brought bread, cheese and sausage for lunch. With the food, he downed two or three glasses of chambertin . (This was not the famous Burgundian chambertin so prized by wine experts but a local homemade wine made from the district's pinot noir grapes and known in the patois as piquette.) Jean Lanfray's piquette was celebrated for being the strongest in the area. Lanfray could have paraphrased Will Rogers' famous remark about men and said that he had never met a drink he didn't like.

At three P.M., he took a wine break - two more glasses of his piquette. At 4:15, he accepted another glass of red wine offered by a neighbor. At 4:30, the day's work over, Lanfray, his father and his brother dropped into a cafe and he had a cup of black coffee laced with brandy. Later, when the police and psychiatrists delved into his behavior pattern, they found that he drank every day two to two and a half liters of vin ordinaire and two to two and a half liters of the stronger piquette - about six quarts in all. Besides this, he consumed several brandies and cordials plus one or two absinthes a day.

It was then about five P.M. Jean Lanfray and his father went home. There, they each polished off a liter of piquette. Jean's wife was in a bad mood. Besides having two small children to look after, she had to clean the house, cook the meals and help out with the farm chores. She asked her husband to milk the cows. They had a herd of 20 and sold the milk to a local creamery. Lanfray, having put in a hard day of drinking and digging, was not up to milking cows. He ordered his wife to go to hell and milk the cows herself. Then he demanded hot coffee. She put the coffeepot on the stove. She did not say anything. In those days, women who knew what was good for them didn't get sassy with their husbands. Lanfray laced the coffee with a healthy slug of marc, a powerful brandy he made himself. His wife went outside. Sometime later, she returned and said she was going to take the milk to the creamery. Her husband complained that the coffee had not been hot enough. She shrugged. Suddenly, he noticed his boots under the sink - unwaxed. He gave her a further piece of his mind. His father started to leave, not wanting any part of this family quarrel. He said goodbye to his daughter-in-law. She shrugged insolently. Lanfray fils shouted that she should behave more politely to the old man. She shrugged again. He was enraged. He began yelling. And then she yelled back.

"Shut up!" he barked.
She lost her temper: "I'd like to see you make me!"

You would, would you?" he snarled. He went and got his old Vetterli rifle, a long-barreled (33.2 inches), bolt-action repeater that took a magazine of 12 cartridges.

"Don't do anything foolish," the old man pleaded.
"You stay out of this, Poppa, unless you want trouble yourself!"

Lanfray raised his Vetterli, took aim and shot his wife in the head. She fell and died almost instantly. The old man ran out, shouting, "Au secours, secours!"  The oldest daughter ran into the room. She screamed. Jean shot her in the chest. She fell, mortally wounded. Next, he went to the cradle where little Blanche was sleeping. He killed the infant. Then he set out to take his own life. He held out the rifle and tried to aim it at his head, but it was too long. He got a string and tied it to the trigger, passed it behind the trigger bar, then held the free end of the string with one hand and the rifle by the barrel with the other hand. He was thus able to draw a bead on his own head, but he missed his brain; the bullet lodged in his lower jaw. Bleeding profusely, Lanfray tucked the corpse of his youngest girl under his arm. He went into the barn. He lay down on the ground and fell into a deep sleep, where the police found him and took him into custody. He was "dazed and incoherent," according to their account. He was taken first to the hospital in nearby Nyon, where the bullet was removed from his jaw. He fell asleep again at once. Later, he was taken to see his three victims in their coffins. Nurse Marie Blaser said that the murderer wept and moaned over and over, "It is not me who did this. Tell me, O God, please tell me that I have not done this. I loved my wife and children so much." Lanfray insisted he did not remember anything about the murders.

On September 3, 1905, a Sunday, the citizens of Commugny held a mass meeting in the schoolhouse. The villagers, horrified by the crime, learned after an autopsy on Mme. Lanfray that she was four months pregnant with a male fetus. The community had to find a scapegoat. Absinthe became that scapegoat.

At the meeting, speaker after speaker denounced the liquor. "Absinthe," declaimed the mayor, "is the principal cause of a series of bloody crimes in our country." The citizens voted to petition the local legislature to ban absinthe in their canton of Vaud. Within a few days, 82,000 people signed—including women, who did not then have the right to vote."

These days, it's pretty much accepted that Jean Lanfray only had a couple of glasses of absinthe during his binge.

OTH, he did use a gun to kill his family: not any other weapon.
