PRETORIA, South Africa — The chief prosecutor in the Oscar Pistorius trial urged the judge today to send the Olympic athlete to prison for at least 10 years, calling it the minimum acceptable term and noting the horrific nature of the shooting death of Reeva Steenkamp.

Judge Thokozile Masipa is expected to announce Pistorius’ sentence on Tuesday.

She adjourned court today after chief prosecutor Gerrie Nel and chief defense lawyer Barry Roux presented their final arguments for sentencing, summing up the testimony in the weeklong hearing.

Masipa found Pistorius guilty last month of culpable homicide for negligently killing Steenkamp, but acquitted him of murder. Culpable homicide is comparable to manslaughter and Masipa has a wide range of options on Pistorius’ sentence. She could issue a suspended jail sentence and a fine, order the 27-year-old Paralympic champion to go under house arrest, or send him to prison for up to 15 years.

Nel said to Judge Masipa: “The minimum term that society will be happy with is 10 years in prison.”
