South African judge Thokozile Masipa has wide latitude in deciding the sentence after several days of legal arguments and testimony that will begin Monday. Last month she convicted the double-amputee runner of culpable homicide, or negligent killing. Sentences for such a crime can range from a suspended sentence and a fine to as many as 15 years in prison.
Pistorius, once a celebrated athlete who ran in the 2012 Olympics, was charged with premeditated murder in a televised trial that transfixed many people around the world, but Masipa found him not guilty of that charge.
She drew criticism from some South Africans who thought Pistorius could at least have been convicted of a lesser murder charge on the grounds that he knew a person could die when he fired four bullets through a toilet door in his home early on Valentine's Day last year.

Predictions About the Sentence VarySouth African lawyers vary widely in predictions about what kind of sentence Pistorius will get. Some say he is unlikely to go to jail because defense lawyers will successfully argue that the athlete is a first-time offender with a disability that would subject him to particular hardship in prison, while others anticipate that Pistorius will be sentenced to some prison time because of the severity of his crime.
"I think that the probabilities are that the judge will send him to prison for a certain period, but not a very long one," said George Bizos, a human rights lawyer. He did not specify the length of a possible jail term.
