[Forensic Pathology] The blood on the floor is beyond recovery - it has landed in a complex slurry of broken glass, nutrient fluids and blood from the two slain clones. You are ankle deep in the stuff and every time you lift your armoured boot it leaves an impression like you have stepped in gelatin.

You might still find a sample splashed into a wall, but that itself is no easy matter. Bolt rounds are mass-reactive explosive projectiles, meaning any splatter has been thrown in wild directions and potentially mixed with the blood of the clones who died to the same manner of weapon. Spend one point to obtain a clean sample.

[Military Science] That is the tread of a power armoured boot all right, but Emperor help you if you can figure out the mark of the armour from that alone. Maybe if you could somehow preserve the impression before the sludge loses cohesion you could reference it later but fuck knows how you'd do that.

[Research] Though - when in doubt, you can always do worse than asking a Tech Priest.
