As her magically boosted focus fades away, Forty repeats the familiar ritual of cursing herself for not being able to do proper magic, then turning her anger toward the world at large. After a few moments of standing with her arms crossed, scowl on her face, and violence in her stare she mutters to herself "No fragging point in standing around Forty -- you don't work for the Corp, you don't get coffee breaks. You might be a dumb thug but you gotta do something useful."
But what to do? She already had Bolt check for traces of magic, and the spirit couldn't find anything interesting. She looks around at the carnage again, the blood and bullet wounds, then replays the camera footage that Ravener shared with the team. Finally she flicks on her microphone and shares ">>The invis says someone good at magic. But looks to me like all the killing was with guns. No spirit on the cam, no fireballs, no nobody acting strange for what was going on. I'm gonna look to see if anyone doesn't have the right kind of damage on 'em for guns and knives, to be sure. But I don't think their caster was a killer."
Then she gets to work, checking over the bodies one by one. She doesn't know much about wounds besides that they hurt, but she figures she'd notice if one of the corpses was burnt in places, or didn't have any bloody holes in it. Thinking through what her spirits can do, she also looks for signs of vomit. Of particular interest is the part of the room killed last, since she would have used guns to herd people into waiting spirits.
