Blade runner Oscar Pistorius will learn his sentence today for the murder of his girlfriend, Reeve Steenkamp, on Feb. 14, 2013. An appellate court had thrown out the previous conviction for South Africa's version of what we call manslaughter and his 5-year sentence. The high court, instead, found him guilty of murder where he faces at least 15 years in prison. He served one year of the original five years. The judge, however, could find mitigating circumstances to justify a sentence less than 15 years.
