The Niles Canyon ghost story is the Northern California variation on the vanishing hitchhiker archetype.
 There are many different variations of this story depending on whom you ask.
 All stories include a girl being involved in some sort of motorized vehicle accident on February 26 (year often changed).
 One variation of the story includes a girl being involved in a car crash on Niles Canyon road (off the 680 freeway in Sunol, California) on the way to her prom.
 The girl died on impact and to this day is said to haunt Niles Canyon road every February 26.
 The tale of the haunting goes that people traveling along Niles Canyon road (now Highway 84) on the night of February 26 will see a normal-looking high school-aged girl walking along the road in a prom dress (many people have said it is white).
 People traveling along the road (mostly those traveling alone) have said to have stopped and offered the girl a ride.
 She accepts the ride, giving the driver an address across the bridge (either Dumbarton or Bay Bridge depending on the storyteller).
 Once the driver gets to the beginning of the bridge, the girl will disappear.
 Sometimes people have gone to the address to find that a girl many years ago matching that description once lived there.
 Today, many people will travel along this treacherous pitch black road in the hopes of catching a glimpse of the Niles Canyon ghost.
Jeffrey James Weise (August 8, 1988 – March 21, 2005) was an American teenage mass murderer and spree killer, who was a student at Red Lake Senior High School in Red Lake, Minnesota, located on the reservation of the Ojibwe people.
 He murdered nine people in a shooting spree on March 21, 2005.
 He killed his grandfather and his grandfather's companion before going to the reservation high school, where he murdered seven more people and wounded five others.
 He committed suicide before being captured by police.
The Sri Lankan Civil war was very costly, killing over 100,000+ civilians and 50,000+ fighters from both sides of the conflict.
 The "Tamil Centre for Human Rights" recorded that from 1983 to 2004, 47,556 Tamil civilians were murdered by both the Sri Lankan government and IPKF forces.
 Another organization called NESOHR published that from the beginning of the war to the , 4000 to 5000 Tamil civilians were killed in large scale massacres, with a total civilian death of around 40,000.
 Civilian casualties that occurred on 2009 is of major controversy, as there were no organizations to record the events during the final months of the war.
 The Sri Lankan government revealed that 9,000 people were killed in the final months of the war, but it did not differentiate between LTTE cadres and civilians.
 The UN, based on credible witness evidence from aid agencies and civilians evacuated from the "Safe Zone" by sea, estimated that 6,500 civilians were killed and another 14,000 injured between mid-January 2009, when the "Safe Zone" was first declared, and mid-April 2009.
 There are no official casualty figures after this period but estimates of the death toll for the final four months of the civil war (mid-January to mid-May) range from 15,000 to 20,000.
 A US State Department report has suggested that the actual casualty figures were probably much higher than the UN's estimates and that significant numbers of casualties weren't recorded.
 A former UN official has claimed that up to 40,000 civilians may have been killed in the final stages of the civil war.
 Several human rights groups have even claimed that the death toll in the last months of the war could be 70,000.
 The Sri Lankan government has denied all claims of causing mass casualties against Tamils, arguing that it was "taking care not to harm civilians".
 Instead, it has blamed the LTTE for the high casualty numbers, stating that they used the civilians as human shields.
 Both the Sri Lankan government and the LTTE have been accused by the U.N for war crimes during the last phase of the war.
Seung-Hui Cho (in Korean, properly Cho Seung-Hui; January 18, 1984 – April 16, 2007) was a South Korean spree killer and mass murderer who killed 32 people and wounded 17 others armed with two semi-automatic pistols on April 16, 2007, at the Virginia Polytechnic Institute and State University in Blacksburg, Virginia.
 An additional six people were injured jumping from windows to escape.
 He was a senior-level undergraduate student at the university.
 The shooting rampage came to be known as the Virginia Tech shooting.
 Cho committed suicide after police breached the doors of the building where most of the shooting had taken place.
 His body is buried in Fairfax, Virginia.
The El Ayyat train disaster happened at 02:00 on the morning of 20 February 2002 in an eleven-carriage passenger train travelling from Cairo to Luxor.
 A cooking gas cylinder exploded in the fifth carriage, creating a fire which engulfed seven third-class carriages, reducing them almost to cinders.
 The initial number of dead given by officials at the time was 383, all Egyptians.
 However, considering that seven carriages were burnt to the ground, and each carriage was packed with at least double the maximum carrying capacity of 150, this number is considered by many people to be a great underestimate.
 The dubious nature of the given death toll lies with the absence of a full passenger list; accounting for those missing was almost impossible at the time.
 In addition, the fire was so intense and the carriages so badly burned that many corpses had been reduced to ash.
 As there was no means of communication between the driver and the rear carriages, the driver did not know of the fire until about two hours after it had begun, resulting in many people, attempting to flee from the overcrowded carriages, jumping to their death.
 Some important Egyptians have commentated that the official number of 383 dead is grossly inaccurate and was an attempt to lessen the damage done to the reputation of the government.
 Many people consider a number of about 1000 deaths to be more accurate.
Charles Joseph Whitman (June 24, 1941 – August 1, 1966) was an American mass murderer who became infamous as the "Texas Tower Sniper".
 On August 1, 1966, he murdered his mother and wife in their homes, then went to the University of Texas at Austin where he shot and killed three people inside the university's tower.
 He then went to the tower's 28th-floor observation deck, where he fired at random for some 96 minutes, killing an additional eleven people and wounding thirty-one before being shot and killed by police.
 Sixteen people were killed in total; a 17th victim died in 2001 from injuries sustained in the attack.
Kevin P. Granata (December 29, 1961 – April 16, 2007) was an American professor in multiple departments including the Departments of Engineering, Science and Mechanics (in which he was tenured) and Mechanical Engineering at Virginia Polytechnic Institute and State University (Virginia Tech), Blacksburg, Virginia.
 Granata held an additional academic appointment as a professor in the Virginia Tech-Wake Forest School of Biomedical Engineering and was an adjunct professor at the University of Virginia in the Department of Orthopedic Surgery.
 During the Virginia Tech shooting, he shepherded students into his office in order to safeguard them.
 He was then killed by Seung-Hui Cho after he went to investigate and intervene.
Kume no Heinai-dō (久米平内堂 ) is a small folk shrine located in Asakusa in Taitō, Tokyo.
 The shrine houses a stone statue of Kume no Heinai, a samurai from the early Edo period (17th century).
 According to the Asakusa tourism bureau, there are few facts about the life of Kume no Heinai, but he is said to have died in 1683.
 Oral tradition holds that Heinai excelled in Kenjutsu, the martial art of swordsmanship, killing many people over the years.
 In the latter half of his life, he is said to have lived in the Sensō-ji temple in Asakusa where he devoted himself to Zen-Buddhism and held religious services in honor of the people he killed.
 Shortly before his death he ordered his followers to carve his likeness on a stone and bury it near the Niōmon – the entrance to the Buddhist temple and a busy district in the city.
 His wish was to have his statue be stepped on by as many people as possible in order to expiate the crimes he committed in life.
 The statue was eventually retrieved and is now stored inside the shrine itself.
 It is because of this that the shrine initially carried the name "Fumitsuke" (踏みつけ ) , which means "to tread on", but over time the meaning was lost and the shrine's name came to be spelled 文付け, which means "love letter".
 Both words are pronounced "Fumitsuke" and the shrine is now worshipped by the general public as a deity of marriage and match-making.
 Kume no Heinai-dō was destroyed in March 1945 during World War II.
 The current temple was rebuilt in October 1978.
Rukn ud din Firuz was the fourth sultan of the Mamluk Sultanate (Slave Dynasty), who ruled for a little over six months, which is said to be a very less time compared to other rulers and was the Governor of the Royal state of Badayun.
 He was the son of Iltutmish (1211–36) and was raised to become Iltutmish's heir.
 As the newly crowned ruler he had the following qualities; physical aristocracy, courteous behaviour and resolved consciousness.
 He was a self-endowed person and spent much of his time resolving in music.
 Taking advantage of his vulnerability as a king, his mother Shah Turkan embraced the entire power of the throne to herself.
 As a person, Shah Turkan was a tyrannical ruler on her command many people of the kingdom were killed.
 However after Iltutmish's death in April 1236 he was viewed as being unfit to rule and was murdered in November 1236.
The May 2004 Caribbean floods were a flood event that took place in the Caribbean Islands, mainly Hispaniola and some parts of Northern Puerto Rico from May 18, 2004 to May 25, 2004.
The storm caused significant rainfall, with over 9.7 inches of rain falling at the most in Haiti, and 10 inches falling at the most in the Dominican Republic.
 These floods were caused by over two weeks of persistent rain in the Caribbean area, which eventually caused the landslides that killed many people.
 The floods caused much damage in Haiti and the Dominican Republic, with over 1,300 homes being destroyed and about 2,000 people being killed.Due to this destruction, nearly 15,000 people were displaced with nowhere to live.
 The area that felt the worst of the flooding was the town of Jimani, near the border of Haiti and the Dominican Republic.In fact, the destruction present at Jimani was so bad that Dominican president Hipolito Mejia declared a national day of mourning after seeing the effects of the storm.
