The dark journey from acclaimed Olympian to accused murderer took double-amputee sprinter Oscar Pistorius just five months — and four gunshots. The South African track star, once a source of global inspiration, was locked inside a South African jail for the vicious Valentine's Day murder of his gorgeous model girlfriend.
Gun-loving Pistorius, dubbed the "Blade Runner" for his prosthetic carbon-fiber legs, was alone with blonde Reeva Steenkamp when the gunfire erupted inside his tony home around 3 a. Thursday, police said. When cops arrived, a bloody Steenkamp, 30, was dead from four bullets to the head and upper body. Pistorius, a six-time Paralympic gold medalist, was questioned for hours and then charged with her slaying.
The suspected murder weapon, a 9-mm. As Pistorius sat in a jail cell awaiting a Friday court date, forensic investigators scoured the murder scene for evidence against the first double-amputee to compete in the Olympic Games. Neighbors and witnesses were also grilled by police about the killing that transformed the sprinter from courageous role model into the O. Simpson of South Africa. Authorities will ask a judge to hold the so-called "fastest man on no legs" without bail pending a murder trial in a slaying that reverberated worldwide.
The runner's family delivered a home-cooked meal, a pillow and fresh blankets to the jailed Pistorius, according to TMZ. Pistorius, a South African national hero honored as one of Time magazine's most influential people in the world, was previously investigated for domestic violence, authorities revealed after his arrest. The prior attacks occurred in the same home where Steenkamp was killed, although they reportedly did not involve the leggy model cited twice as one of the world's sexiest women.
In a particularly heartbreaking touch, the slain Steenkamp was outspoken in her calls for an end to violence against women.
But she was also close with Pistorius and referred to her boyfriend of four months as "my boo" on her Twitter account. Pistorius, cheered by 80, fans at the London Olympics last summer, was greeted by a horde of paparazzi Thursday as cops led him from the Boschkop police station. The unlikely athlete covered most of his face with a gray workout jacket as photographers fought for shots of the newly accused killer.
His lawyer declined comment pending the Friday hearing. But neighbors told police they had "heard things that happened earlier in the evening and during the shooting," Buekes said.
Pistorius had a history with guns, and enjoyed target practice. A London newspaper profile of the runner last year noted that he slept with a pistol alongside his bed and a machine gun near a window.Nv45ab2 rebuild kit
And a Twitter post in November found the sprinter musing about "getting home to hear the washing machine on and thinking it's an intruder" — and then "going into full combat recon mode.
A Nike ad featuring Pistorius used the tagline "I am a bullet in the chamber" was yanked from the runner's website after his arrest.

The circumstances of the incident are still unclear but police in South Africa said they would oppose bail when the Paralympic gold medalist appears in court Friday. The hearing was scheduled for Thursday afternoon but was delayed to give forensics investigators time to do their work, the Associated Press reported. Police in South Africa do not name suspects in crimes until they have appeared in court but police spokesperson Brigadier Denise Beukes said that Pistorius was at his home after the death of the victim and that "there is no other suspect involved," The Associated Press reported.
The original source of the report appears to be Beeldan Afrikaans-language daily newspaper. Local radio also reported on the fatal shooting.Sd40 sight mount
Some media commentators speculated that the victim may have been in the act of surprising Pistorius for Valentine's Day.
Steenkamp had posted on Twitter about Valentine's Day on Twitter. Police spokesperson Captain Sarah Mcirca confirmed to South African media that a woman was shot in the arm and head. A 9mm pistol was recovered at the scene.
Brigadier Denise Beukes told members of the media in South Africa that police were not the source of the report that the victim was mistaken as a burglar. Our detectives have been on the scene, our forensic investigators have been on the scene and the investigation is ongoing. South African police said that there had been "previous incidents" of a domestic nature reported at Pistorius' home.
Pistorius, 26, made history by being the first double amputee to take part in the Olympics. Known as the "Blade Runner" for his use of carbon fiber prosthetic blades, Pistorius won gold medals in the 4 x meter relay and meter individual events at the Paralympic Games in London. He was born without the fibula, the long, slender bone running along the outside of the leg from below the knee joint and down to the ankle, in each of his legs, information on his website says.
Pistorius is a huge star in South Africa and is viewed as an ambassador for the nation's sporting achievements. InTime magazine named him as one of the world's most influential people. He has sponsorship deals with brands including Nike, Oakley and the French fashion designer Thierry Mugler. The South African Sports Confederation and Olympic Committee said that it was not in a position to comment on the alleged fatal shooting.
We didn't really speak about my disability, not because it was a topic that was taboo And that's the mentality that I've had. He's sad at the moment. The navigation could not be loaded.It was one of amazing triumph and unspeakable tragedy. He overcame having both feet amputated at 11 months old due to a congenital defect to become a world-class sprinter and an Olympian for South Africa in the Olympics.
He was found guilty of culpable homicide and sentenced to five years in prison.
Where is Oscar Pistorius today? Oscar Pistorius made his international debut at the Summer Paralympic Games. While Pistorius is classified as a T43 or double below-knee amputee, he competed in the T44 division, which is designated for single below-knee amputees.
Pistorius finished third and earned a bronze in the meters. He then proceeded to set a world record in the meters with an astonishing time of He dominated the next two Paralympics winning multiple medals in the, and meter events. Oscar Pistorius became a worldwide sensation in when he qualified for the Summer Olympics in both the meter race and the 4 X meter race for South Africa. In thePistorius finished second in his qualifying heat and then placed eighth in the second semi-final.
He had better success in the relay where the team made it to the finals and finished eighth. Six months after carrying the South African flag in the closing ceremony, Oscar Pistorius shot and killed his girlfriend, model Reeva Steenkamp, in what he described as an intruder incident.
The story shocked the world. Pistorius went to trial in March After one delay, in which his defense team claimed he had generalized anxiety disorder and might not be criminally responsible for the shooting, the trial resumed in July.
A couple of months later, Pistorius was found guilty of culpable homicide and one firearm-related charge of reckless endangerment. He received a prison sentence with a maximum of five years for culpable homicide and a concurrent three-year suspended prison sentence for the separate reckless endangerment conviction.
In Julythe same judge who initially sentenced Pistorius to five years, amended his sentence, adding an extra year.
That decision also did not sit well with prosecutors, who said they would take their appeal back to the Supreme Court of Appeal and request a lengthier sentence. In DecemberOscar Pistorius filed papers to appeal the increased sentence and have his previous six-year sentence reinstated. He is not eligible for parole until at least Home Sports.
Oscar Pistorius and his amazing rise to fame.Investigators identified the man as Robert Howard searcha University of Arkansas search medical student who competed in track and field in the and Olympics, said medical school police Capt. Bryan Patterson. Leslie Taylor, a spokeswoman for University of Arkansas for Medical Sciences, said campus police received a call early Saturday from someone concerned about a medical student. Police arrived at the dormitory room and tried to talk to the man, but he jumped out of the window about 20 minutes later, Patterson said.
Later that morning, investigators went to a private residence and found the student's wife, Dr. Robin Mitchell searchstabbed to death. Mitchell was chief resident in neurosurgery at the medical school.
Howard finished eighth in the triple jump at the Olympics in Atlanta and seventh at the Games in Sydney.

Oscar Pistoriusthe South African Olympic and Paralympic athlete who killed his girlfriend, Reeva Steenkamp, by firing four bullets through a closed toilet door, has been sentenced to a lower than expected six years in prison.
The sentence, given by Judge Thokozile Masipa in the high court in Pretoria, may be the final chapter in a story that attracted intense worldwide attention. Pistorius, who gained global fame when he reached the semi-finals of the m sprint at the Olympics in London, was taken down to cells immediately after the sentencing at The former athlete showed little emotion, but looked relieved.
His family made no immediate statement. The sentence was much lower than many had expected and public prosectors had demanded the mandatory minimum for murder of 15 years. Nothing will bring Reeva back. The record has been set straight and justice done. The truth will always prevail. After an appeal by state prosecutors he was convicted of murder last year, a crime which carries a mandatory sentence of 15 years. Pistorius arrived for court looking anxious but healthier than during the hearings last month.
He hugged members of his legal team and his family. Relatives of Pistorius and those of his victim filled a bench along the front of the courtroom. Prosecutors had called for the mandatory minimum, saying that a message needed to be sent in a country with extremely high levels of violent crime, often involving firearms.
Defence lawyers had argued that a non-custodial sentence — such as community service — would be most appropriate. The judge said she had to balance the interests of society, the accused and relatives of the victim.Shadow kwgt 4pda
He cannot be at peace. She also stressed that a court should not be swayed by public opinion but that punishment must also reflect the seriousness of the offence. Pistorius, who became the first double-leg amputee to participate in the Olympics inwas a hero to many in South Africa and across the world. But the fairytale story of tenacity and talent overcoming disability ended abruptly in the early hours of 14 Februarywhen Pistorius, whose lower legs were amputated when he was 11 months old, shot Steenkamp dead with a 9mm handgun.
Pistorius has always denied deliberately shooting Steenkamp, claiming that he believed a burglar was hiding in the toilet in his home. Prosecutors said he killed Steenkamp in a jealous rage. The trial revealed a different and much darker side to Pistorius: a taste for fast cars and guns — and a short temper.
His defence lawyers argued that, though a hero to many, the truth was that the athlete was a deeply anxious man.
On the third and final day of the sentencing hearing last month, Pistorius removed his prosthetics to hobble on his stumps across the courtroom to demonstrate his physical vulnerability. Then there was the other [Oscar] without his prostheses who was a vulnerable, anxious man. More recently, I saw a third Oscar that really has almost given up. His spirit seems broken. I believe he is quite ill. I smoke my cigarettes. During the sentencing hearing Gerrie Nel, leading the prosecution team, told Masipa any sentence needed to consider the needs of the broader community and send a strong message to deter violent crime.
The killing and the trial also held a mirror to South Africa more than 20 years after the end of apartheid and the coming of democracy amid widespread disillusionment at a perceived failure to achieve the lofty goals of that time.

But the mapping of computer science data types to statistical data types depends on which categorization of the latter is being implemented.
Other categorizations have been proposed. Whether or not a transformation is sensible to contemplate depends on the question one is trying to answer" (Hand, 2004, p.
The probability distribution of the statistic, though, may have unknown parameters. Commonly used estimators include sample mean, unbiased sample variance and sample covariance.
Widely used pivots include the z-score, the chi square statistic and Student's t-value. Between two estimators of a given parameter, the one with lower mean squared error is said to be more efficient. Furthermore, an estimator is said to be unbiased if its expected value is equal to the true value of the unknown parameter being estimated, and asymptotically unbiased if its expected value converges at the limit to the true value of such parameter.
Other desirable properties for estimators include: UMVUE estimators that have the lowest variance for all possible values of the parameter to be estimated (this is usually an easier property to verify than efficiency) and consistent estimators which converges in probability to the true value of such parameter.
This still leaves the question of how to obtain estimators in a given situation and carry the computation, several methods have been proposed: the method of moments, the maximum likelihood method, the least squares method and the more recent method of estimating equations. Interpretation of statistical information can often involve the development of a null hypothesis which is usually (but not necessarily) that no relationship exists among variables or that no change occurred over time.
The null hypothesis, H0, asserts that the defendant is innocent, whereas the alternative hypothesis, H1, asserts that the defendant is guilty.
The indictment comes because of suspicion of the guilt. The H0 (status quo) stands in opposition to H1 and is maintained unless H1 is supported by evidence "beyond a reasonable doubt". However, "failure to reject H0" in this case does not imply innocence, but merely that the evidence was insufficient to convict. So the jury does not necessarily accept H0 but fails to reject H0.
While one can not "prove" a null hypothesis, one can test how close it is to being true with a power test, which tests for type II errors. What statisticians call an alternative hypothesis is simply a hypothesis that contradicts the null hypothesis.Aldo coppola barvikha
Working from a null hypothesis, two basic forms of error are recognized:Standard deviation refers to the extent to which individual observations in a sample differ from a central value, such as the sample or population mean, while Standard error refers to an estimate of difference between sample mean and population mean. A statistical error is the amount by which an observation differs from its expected value, a residual is the amount an observation differs from the value the estimator of the expected value assumes on a given sample (also called prediction).
Mean squared error is used for obtaining efficient estimators, a widely used class of estimators. Root mean square error is simply the square root of mean squared error. Many statistical methods seek to minimize the residual sum of squares, and these are called "methods of least squares" in contrast to Least absolute deviations. The latter gives equal weight to small and big errors, while the former gives more weight to large errors.
Residual sum of squares is also differentiable, which provides a handy property for doing regression. Least squares applied to linear regression is called ordinary least squares method and least squares applied to nonlinear regression is called non-linear least squares.
Also in a linear regression model the non deterministic part of the model is called error term, disturbance or more simply noise. Measurement processes that generate statistical data are also subject to error. Any estimates obtained from the sample only approximate the population value. Confidence intervals allow statisticians to express how closely the sample estimate matches the true value in the whole population.
From the frequentist perspective, such a claim does not even make sense, as the true value is not a random variable.Rosie's Tiara (4) 1. Music Scene (6) 5.Oscar Pistorius trial: The ballistics evidence
A Nature Research Journal EditorialWorthy reports are as frequently encountered in Washington DC as grand monuments and are just as likely to be ignored by the locals. But lawmakers will fail their constituents if they manage to ignore the latest study on competitiveness by the National Academies.
The report, Rising Above the Gathering Storm, addresses resurgent fears that the United States' longstanding global leadership in research and development is on the wane. Written by a panel chaired by Norman Augustine, former chief executive of technology corporation Lockheed Martin, it offers several concrete recommendations designed to keep that leadership intact.
Whether the US government pays any attention or not, its competitors will find the panel's findings well worth a look. Whereas previous studies of this kind have focused primarily on research funding, this one concentrates much of its attention on improving the nation's scientific literacy.
It calls for the annual recruitment of some 10,000 science and maths teachers, proposing that science undergraduates be lured into the classroom with generous scholarships, with the lofty goal of improving science education at school for some 10 million people. This proposal may appear to some US politicians to be central planning run amok and it doesn't really address the low pay and social standing of teachers in the United States.
But it does have potential and precedent: an existing programme called Teach for America has succeeded in recruiting thousands of young college graduates to teach in the nation's most troubled neighbourhoods. Other recommendations of note include a call for the creation of a new energy-research agency that would conduct low-cost, high-risk, high-reward research projects.
