Point 1 - When the two first start talking
Point 2 - He rips her dress
Point 3 - he threw her pendant in the tub

Story related, impossible to miss.
Chapter Three. Once you have examined the crime scene, the environment will turn red and ghosts will appear just as they did in the Chapel. You must examine the scene that plays before you at three set points in order to further the story: as they hug, as they start to fight, and as the woman is pushed away.
You can die during these visions, so be aware of when the screen starts to become black. Moving away from the vision will halt the danger.
Story related. I suppose you could miss it, if you keep dying and then just quit the game... but all you have to do is interact with the vision in a timely fashion and move slightly away from danger before interacting again.
