Pretoria - Oscar Pistorius's lawyers intend calling four witnesses during the paralympian's sentencing proceedings in the High Court in Pretoria.
Judge Thokozile Masipa on Monday morning asked Barry Roux, for Pistorius, how many witnesses he would call.
He said three, which he did not expect to take long, and a fourth person from the correctional services department.
Masipa asked the same question of prosecutor Gerrie Nel.
“It's difficult to say My Lady, we can't anticipate what the defence will lead,” he replied.
The first defence witness, Pistorius's therapist, psychologist Lore Hartzenberg then made her way to the stand, holding her bag and a bottle of water.
Four police tactical response officers were in court, two on either side of the judge's bench.
Pistorius arrived at the court on Monday morning amid heavy security. He was escorted by a group of police wearing bulletproof jackets while a media contingent swarmed around him.
When he arrived in court, Pistorius mouthed "morning" to Reeva Steenkamp's parents June and Barry, who did not respond.
Before his arrival security guards wheeled out a bag scanner and a walk-through metal detector to the entrance of the court GD. This was the first time the devices were placed at the court room.
Pistorius was convicted of culpable homicide on September 12 for the shooting of Steenkamp on Valentine's Day last year.
Judge Thokozile Masipa found him not guilty of murdering Steenkamp, but convicted him of culpable homicide.
With regard to firearms-related charges, Masipa found Pistorius guilty of firing a Glock pistol belonging to his friend Darren Fresco under a table at Tasha's restaurant in Johannesburg in January 2013.
However, she found him not guilty of shooting through the open sunroof of a car with his 9mm pistol while driving with Fresco and ex-girlfriend Samantha Taylor in Modderfontein on September 30, 2012.
