It's really muddled. In the 911 call, CW says "My daughter is freaking out." It was never made clear if SHE heard her freaking out, or if IF said she was freaking out. The PI did say IF said the intruder hit the sister, BUT did not say IF said that in the 911 call.
"Her brother called Leila’s father and girlfriend who were attending a Little League baseball game at the time to tell them he saw a man hitting his sister and that he scared the stranger from the house." To me, that's quite unclear. It does not ever say he DID tell them this, only that called in order to tell them. (But did he? What DID he tell them? On the 911 call we do hear, it's very clear that CW thought she was OK. She said as much.)
BUT, the lawyer has already said IF could be making the intruder up. "An attorney for the 12-year-old boy said the youngster might have lied about seeing a long-haired intruder fleeing the scene, but that doesn't make the boy the killer."
We don't know what "may have" means. Does he mean it's possible he made it up, but I'm not sure at this point? Or, does it mean he "may have" made it up, because he didn't see the intruder and was scared? There is such a huge difference between the two scenarios. In the first, there could be no intruder. In the second, there is an intruder he just didn't see. The lawyer is being very vague, but still...is not really fighting for the intruder theory...it seems.
As always, just my opinion!! I do agree completely, that we don't know what he saw...of anything. We might never know.
