From the camera angle shown, the catcher initiates contact with intentional excessive force above the first runner's waist.
I have a dead ball right there because of malicious contact on the catcher. Malicious contact always is an immediate dead ball. Score the first run. Eject the catcher. Place the batter-runner where appropriate.
I don't. I think he didn't know where the runner was and lunged, creating extremely violent, albeit unintentional, contact.
