I also feel bad for speculating but it feels unethical to me to try and sell a business just days after an employee had died without mentioning it at all to potential buyers, he commented today saying that vans would be sold etc - at the very least I'd like to think I would hold off on the sale...
That said, while I was digging I also found that his company cleaned windows that belonged to another window cleaner and posted a slip requesting payment as though the customer was theirs, so his morals are questionable
I'm assuming the road is open now so the police have investigated and have a good idea of what's happened. He would surley have been pulled by now. If there was anything dodgy about the van I'm sure the other workers would be getting it out there too. It will be reported online somewhere.
