Look at various notes on the wall.

You hop off your skate-truck and look at the notes on the wall, quickly finding them to be time punch cards. Most of the employees seem to be out at the moment, save for Grand Homme, who has yet to punch out for tonight. The most recent punch out was one Custodial Staff, who clocked out... five minutes before the murder was reported. There's a possibility that this Custodial Staff fellow and Grand Homme are related, since Grand Homme's last shipment was ten minutes before the murder.
