Ron Marsh said he had contacted Legacy Independent Funeral Directors when his mother Joyce Moulton died in September 2023, aged 98.
He said Bush was professional and the service he organised was “excellent”, but the family never received her ashes, with attempts to contact Legacy going unanswered.
In March 2024, he was visited at his Surrey home by police family liaison officers who told him his mother’s body had been found during a raid at Legacy’s premises in Hull.
“I was gobsmacked. It was just not anything I ever thought happened, would happen, and certainly not happen to my mum.
“I couldn’t comprehend something like that happening,” he said.
“Because there is no legislation with regard to funeral directors, and therefore, there’s no checking to see that once a funeral service has been had, if it’s not at the crematorium or at the church, that body has actually been either cremated or buried.
“So it still gets to me and I think it will for the rest of my life,” he added.
