I don't think it was a butt dial - I think it was OP trying to call security but not being able to speak. Then Baba called back. Those were the only two calls.
Baba misremembered the order of the calls
I agree it wasn't a butt dial.
And if he called and was sobbing with no one around, then it flies in the face, I think, of someone calculatingly trying to cover his crime immediately after the shooting.
I, too, think Baba may have misremembered the order of the phone calls. Phone records show that OP called Baba first. When Baba called OP back, OP said "Everything is fine."
Whether or not OP intended to call Baba is a question I have. He may have accidentally pushed a speed dial button, or he may have called Baba on purpose. OP sounding like he was crying during that call to Baba (which lasted about 9 seconds) is proof of nothing, IMO.
If he called Baba on purpose, why then did he tell Baba that everything was fine when Baba called him back less than a minute later?
I think it's because OP didn't want security to come to his house, both before he killed Reeva and afterward. When he heard the alleged mysterious noise that he claims he thought was a burglar, he didn't press the panic button, which would have alerted security immediately that he needed assistance, nor did he tell Baba what had happened after he shot Reeva.
I would have expected an excited utterance at that particular point (when he was on the phone with Baba). I would expect OP to have blurted out the intruder story to Baba, if OP's belief in the intruder story is true. Such is the nature of excited utterances. They come out automatically without thinking or forethought. They don't occur later after someone has had time to think or reflect.
Instead of an excited utterance about a mistaken belief in an intruder, OP calmly told Baba "everything is fine". It wasn't until several minutes later, after he carried Reeva downstairs and saw Stander, Stander's daughter Clarice, Baba, and Dr. Stipp, that he said "I shot Reeva by mistake. I thought she was an intruder."
Why didn't he tell Baba "I shot Reeva by mistake. I thought she was an intruder" when Baba called him at 3:22:05?
Personally, I think OP was surprised that so many people showed up on his doorstep so quickly. I think he was only expecting Stander. I think he came up with the "intruder" excuse when he saw all the unexpected witnesses in his foyer and at his door. I think the excited utterance window had closed by that point, and I think he intentionally blamed his actions on a phantom intruder because it was the first excuse he could think of.
1. OP's statement to Baba that "everything is fine" when everything was not fine, but was, in fact, disastrous, and then, when faced with multiple, unexpected witnesses several minutes later, to say that he mistook Reeva for an intruder, seems like an attempt to cover his crime, IMO.
2. Let us also not forget that his personal phone went missing from the crime scene. Someone orchestrated its removal from the house. I think that person was OP, with a little help from his friends, who were allowed to talk with him and comfort him after he killed Reeva.
3. Oh - and after that phone was finally turned over to the prosecution, OP conveniently forgot his whatsapp password.
Collectively, if the above 3 numbered points are not evidence of potentially trying to cover up his crime, IDK what is.
