The detainees made sure that they were foreigners, and without family, so that they would not be claimed. In one operation, they collected more than 5,000 euros.
Those arrested falsified documentation to be able to remove the bodies from hospitals and later sell them to universities for study for 1,200 euros per body. They invoiced a university for carrying out 11 cremations of bodies, once studied, which were not reflected in the invoices issued by any of the incinerators operating in the city.
