So, working theory: Lutran meets the refugees and gets them to board the module that is due to be transferred from the Merchant Docks to his transport waiting in the Public Docks. (The transfers were all done by bot; haulers moved the recently loaded modules to the lock and pushed them out. If it was an inert module, the cargo bots would take it and attach it to its transport. If it was a powered module, the cargo bots would place it on one of the set paths around the station where it would get a go-signal and then head toward its destination. When it arrived, another cargo bot, or the transport itself if it had the right configuration, would attach the module.) With the refugees safe aboard the module, Lutran then goes back to his transport to make sure the module attaches correctly when it arrives and that the refugees get aboard. But it’s not there, the module has been diverted to an unknown destination. Someone else is aboard the transport, and that person kills Lutran. Then that person, who somehow has hacked the PA’s systems, deletes the record of Lutran’s module transfer.
