Apparently a cricket bat was discovered inside Oscar Pistorius's bedroom and it was covered in blood.
"This is a key piece of evidence that police will use in their trial." Mr Basson said.
"The bat is still at the police laboratories where it is being tested to see whose blood is on it.
"A
possible version that the police are looking at is that Mr Pistorius
may have indeed assaulted his girlfriend before shooting at her.
"This is supported by these injuries to her head.
"What
I was told was that she suffered extensive injuries to her head - that
in fact her skull was crushed, at the back of her head which was
probably not caused by one of the bullets that was hit her from where
she was hiding in the bedroom
Mr Basson added that sources close
to the investigation told him that claims the athlete mistook his
girlfriend for an intruder were not backed up by evidence.
He said: "The first shot that was fired allegedly by Mr Pistorius was fired in the bedroom.
"The bed was crumpled, they clearly slept in the bed before the incident happened."
Pistorius
will appear in court on Tuesday for a bail hearing, something police
have said they oppose. Prosecutors also say they will pursue upgraded
charges of premeditated murder against him, which means the athletics
hero could face a life sentence.
Meanwhile Reeva Steenkamp's
father Barry has said that the family was struggling to come to terms
with her death, but revealed: "There is no hatred in our hearts".
