I'm not saying anything about whether it's believable or not. I'm saying that parallel construction is an explanation the government gives of how they found someone. But the government isn't saying they found him from this picture. They're saying they first found him, then subpoenaed his cloud account, then found this picture. Since this picture isn't an explanation of how they found him, it's not parallel construction.
