Mike this is quite serious , ive known wrong deceased going to the crematorium , ive seen one coffin opened in the commital room to remove a ring on someones finger, you have to go to the top to do this, Sheilas name might be in the book of rememberance ,they too will exist, and when the twins were buried Sheilas ashes were buried also in a casket, those caskets are heavy and well built, it should still be in the grave,the funeral directors must have to the crematorium to collect the ashes of Sheila, i used to collect many taking a plastc urn and the staff would transfer the ashes or i would back at the funeral home, Colin would have been given a reciept for the ashes of sheila.
