Cass's lips curled in disdain when he saw the woman in the room, raped, torn up, killed. He hated looking at cases like this, but right now, his distaste for rape and rapists didn't matter.
Instead, he waited for Cormac to be done with the camera, taking in the scene as Cormac worked. When Cormac talked to him, he cast the necessary spells, finding plenty of semen left behind.
'They didn't even try to cover it up,' he said, collecting it, thankful he was a wizard and didn't need more distasteful methods. He followed through on the rest of his observations, casting some of the same spells as before.
'The other one was watching,' he said in distaste. 'Possibly even taking part.' He looked at the woman, shaking his head. 'And she...' He nodded at the woman on the floor. 'Definitely followed them here willingly. The footsteps in the other room matches her shoes and they come into this room too.'
So she'd left her husband, went with what was most likely complete strangers while her husband was killed, then ended up raped and killed herself. Probably not what she expected.
