Five nights at Freddy's: Theories and rumors

Who killed phone guy?

Many fans ask, 'Who killed phone guy?'. Well, Theory 1 suggests that he had the left door closed from foxy, and was checking the Kitchen camera. Freddy was playing his tune in the kitchen, and it was loud enough to hear on the recording. Then, the groaning was chica, who got in,and he put his camera down, but how did Chica kill him if you hear golden Freddy's scream? I heard a theory that he had the door closed, checked the kitchen, heard the jingle, then went to check on the left hall corner. There, Bonnie made a groaning sound(I've heard sometimes when you look at him on camera he groans) and he saw the Fazbear poster, but it was golden Freddy. In this case, he put the camera down and died by golden Freddy. I agree more with the second theory, but I want to change it up at the groaning part. So, he checked the left corner, saw the G. Freddy poster but heard CHICA  groaning. And Chica can interrupt other animatronic's jumpscares, right? So he pulls the camera down and golden Freddy attacks, making the scream, but Chica interrupts without changing the scream. Therefore, both Chica and golden Freddy killed PG. RIP.
