As others have said Exchange, I expect you're on the wind-up but if not, do you think all the following are true/reasonable (if Pistorius is to be believed):
1. No reply, conversation, questions or outbursts at all from Steenkamp after OP says get down and call the police.
2. Blood splatter (lined up with matching splatter on carpet) and jeans, both on top of duvet that Pistorius said had been on the bed is due to Police tampering.
3. Pistorius would hear the window not just slam but slide at the other end of the hallway when standing next to a tripod fan at the other end of the bedroom.
4. Food contents in Steenkamp's stomach were from 7 hours before, or that Steenkamp got up and went downstairs to eat whilst Pistorius slept.
5. Ear witnesses, (notably without exception) who independently identified a women's terrified screams, interspersed with a man's were all mistaken.
Re. the ear witnesses, here's their testimony that the Judge will have to reconcile with Pistorius' version:
Mrs Van der Merwe testimony (paraphrased)
Woke up around 1:56am in the morning (irritated by the woman's voice)
[Her elaboration: It was a woman's voice]
Sounded like someone was involved in fight, people talking in loud voices
[Her elaboration: The person was talking / stopping, it wasn't continuous. It sounded like two people in an argument but I couldn't hear the other person's voice]
It lasted about an hour. I couldn't hear what the person was saying, or in what language the person was talking
I fell asleep again
At some stage I woke up and tried to see if there was something I could see. I couldn't see anything.
Around about 3am in the morning, I heard 4 shots/bangs..
[Her elaboration: bangs were shortly one after another]
[Her elaboration: I didn't hear another other sounds (gunshots)]
After hearing the 4 sounds, there was total silence.
Her husband woke up and said that it was a firearm.
Her husband then called security
Can't remember how long after that I heard someone crying out loud.
I asked my husband who it was and he said it was Oscar
[Her elaboration: I didn't hear any screams]
Dr. Stipps' testimony (paraphrased)
Awakened by 3 loud bangs
Got out of bed, walked to balcony
Heard female screaming (3 or four times, moments later) (could have heard another voice, lower pitch, not included in statement)
Looked out and light was on in Pistorius' bathroom.
Went inside to phone security (no answer)
Heard another 3 loud bangs.
Got through to security (3:15:51am), said they would send someone.
Went outside whilst waiting
Heard man shouting "Help help help"
Security arrived, spoke to them from balcony
Went out to other balcony to watch them and looked at where noises came from and noticed someone moving right to left through the bathroom.
Mrs Stipps' testimony (paraphrased)
3:02am (2:59am?) woke up feeling fluish
Heard 3 loud bangs like gunshots
[Her elaboration: After the first set of shots, there was definitely a female screaming for quite a period]
Could see the light was on at Pistorius' bathroom window from her bed.
Went onto the balcony and could hear a lady's terrified screaming (continuing as they walked out)
At one stage, it sounded as though the screaming was coming closer
She went inside, looked at the clock it was 03:17am (likely 3:14/3:15am as her clock was fast)
[Her elaboration: Just before the second set of shots, there was a male voice in between, you could definitely hear two different voices.]
At this time she heard 3 or 4 more shots
...Could still hear woman screaming up until the 2nd set of shots
After the shots it became quiet.
Ms Burger testimony (paraphrased)
Just after 3am woke up from a woman's terrible screams
Husband also woke up from the screams.
Still sitting in the bed and heard her screams.
She screamed terribly and yelled for help.
Also heard a man scream "help, help, help"
Husband called security, relayed account to 2nd person..
Husband went back to balcony
Was still in bed and heard her screams again, worse, it was more intense
She was very scared, it was a climax
[Her elaboration: it was very traumatic, you could hear it was blood curdling screams, it leaves you cold, the anxiousness in her voice]
Just after her screaming, I heard four shots, gunshots (bang....bang, bang, bang)
After he screamed for help, we did not hear him again.
