Your assailant, Erdred Kenn, appears to have been a freelance gun-for-hire, though without identification credentials his identity and trade are assumed (based upon the information you provided).
The scene was handled by Magistratum officers from the local IV-7 hub. They've determined the names of the two other "guests" who were to join you at Posh Formal Dining, these from the Maitre D'. Destatte assumes they will be pulled in for questioning at the IV-7, and would appreciate if you could get their measure without exposing yourselves. As of yet, the weapon Kenn used has not been identified. Destatte may need to make a formal inquiry for this.
Lastly…
The prayer walls have been droning on about renewing our devotion to His Most Benevolent Emperor as proof against a burgeoning contagion. Devotion is all well and good, as it should be, but I recommend you purchase (at the very least) filter paper masks and avoid physical contact with the proles as additional precautions.
