Oscar Pistorius will spend a fourth night in custody and a day later he will go to court to apply for bail. The case against him, and his version of events, will be laid out in front of the court.
Pistorius will concentrate on defending himself against allegations that he murdered his model girlfriend on Valentine's morning.
The South African press say the weapon is a key piece of police evidence, but Pistorius' family said the death is a 'tragic accident.'
The family and management of Oscar Pistorius have released a statement disputing the murder charge against him 'in the strongest terms'.
