The detective who led the investigation into Robert Bush fears the disgraced undertaker has committed more crimes "we are completely unaware of". Bush was sentenced to 20 years in prison for 67 offences relating to Legacy Independent Funeral Directors. The 48-year-old gave families the wrong ashes and kept their loved ones' bodies after their funerals. Det Supt Al Curtis from Humberside Police said he feared they have "just scratched the surface" of Bush's crimes. Curtis said "the saddest thing" was that he could not reassure previous customers that Bush "acted wholly appropriately" in relation to their loved ones.
