List of mass stabbing incidents (before 2010)

At approximately 9:30 a.m. (UTC+09:00) on 5 June 1931, Graciano Bilas, a 42-year-old Filipino steerage passenger, began stabbing people randomly with a pocketknife aboard the Empress of Canada.

[11] In 1954, Ugandan police constable William Unek used an axe to kill 21 people in one and a half hours near Mahagi, Belgian Congo.

[12][13][14] Three years later, Unek went on another rampage near Mwanza, Tanganyika, killing 36 people using an axe, a knife, a rifle, as well as burning and strangulation.

[24] At around 1:30 pm, Lee stabbed his mother and sister in their flat, Room 5274, Block 8, Un Chau Street Estate.

[27][32] Chief Secretary Philip Haddon-Cave and other government officials, who had coincidentally been visiting the nearby Cheung Sha Wan fish market, arrived soon after to inspect the scene and offer condolences.

[28] After the stabbing, security measures at nursery schools were upgraded, and it was made compulsory for discharged patients of mental institutions to regularly attend psychiatric out-patient clinics.

Lee was charged with six counts of murder,[28] and in April 1983 he was sentenced to be detained in a mental hospital for an unspecified period.

[34] The massacre began at Wirjo's home, where he attacked his adoptive son Renny and his friend Arbaiyah, both 4-years-old, with a parang and a sickle.

After an extensive manhunt, including police, dogs, and the army, Wirjo was found the next day just 5 kilometres (3 miles) west of his house, dangling from the roots of a tree growing over a riverbank.

Guozhen then proceeded to travel to the local market and began to kill individuals at random, including children and the elderly.

Guozhen was eventually subdued by bystanders Huang Guoqin and local CCP party secretary Zhou Youbang.

[42] On 16 July 1990, a mentally ill woman attacked the courtyard of the Jewish Kadimah College's primary school in Central Auckland, stabbing four children with a knife while screaming antisemitic slogans.

This apparently random act of antisemitic violence in New Zealand, a country known to be tolerant of its Jewish community, shocked many.

She then produced a 4-inch, stay-sharp vegetable knife and began screaming antisemitic slogans and a Jewish surname (not one shared by any of the victims), before wildly lacerating these four children.

[47] He had been admitted to the All Saints' Hospital, Winson Green in 1988 following the death of his father, and was diagnosed with schizophrenia and hypomania and depressive psychosis.

After treatment psychiatrists said that he had recovered and he was discharged with directions that he should receive support from the community psychiatric team and continue on his course of drugs for three months.

Jan Twining, 50, was browsing Christmas cards when she felt a tap on her shoulder and turned round, and Morgan slashed her in the neck.

[47] In 2002, he was transferred from the Broadmoor Hospital to a medium security unit where he would be allowed on escorted shopping trips as part of rehabilitation.

[51][52][53] Dương Văn Môn, a member of the Nùng minority, was a poor rice farmer, and was said to have once had an unspecified mental illness.

Yasuaki Uwabe, a 35-year-old former architect, drove a car into Shimonoseki Station and then stabbed passers-by at random, killing five people and injuring 10 others, before being arrested at the scene.

[67][68] After the attack, Yanming ran away from the school, but was arrested hours later after he failed to commit suicide because his mother had reported his location to the Ruzhou police.

[75] The suspect, who carried two knives, stabbed the 27-year-old man to death and hurt at least seven others, while the victims were walking along a short hallway connecting Arakawaoki Station.

[89] The victims were Todd Bachman, a prominent horticulturalist from Lakeville, Minnesota,[90] his wife Barbara, and their female Chinese national tour guide.

[98] The Nonhyeon-dong massacre was a mass murder that occurred in the Gangnam-gu ward of Seoul, South Korea on October 20, 2008, when 30-year-old Jeong Sang-jin (Korean: 정상진) set fire in a goshiwon and slashed several women with a sashimi knife.

[102] At about 8:15 a.m., according to police, Jeong, who lived on the third floor of a four-story gosiwon, a low-cost lodging facility, poured gasoline on his bed and set it ablaze.

Dressed all in black, wearing a headlamp, and hiding his face with a balaclava and goggles, he emerged from his smoke-filled room and, armed with a sashimi knife, two fruit-knives strapped to his legs, and a tear gas gun in a belt holster, began slashing and stabbing the residents of the building who were fleeing the fire.

At 9:20 a.m., Jeong, initially thought to be another victim, was rescued by a fireman from a storage room in the fourth floor where he was hiding.

[103][104][105][106][107][108][109] Jeong Sang-jin, originally from Hapcheon, South Gyeongsang Province, moved to Seoul in 2002, where he scratched a living with part-time jobs as food delivery man or parking valet, though as of April 2008 he was unemployed and had to face severe financial difficulties.

According to unconfirmed reports, he was convicted eight times, once for skipping an obligatory training for military reservists, for which he was fined of 1.5 million won.

[100][105][110][111] Jeong was in severe financial distress and couldn't pay his rent and mobile phone fees for months prior to the rampage.
