Dennis Melnyk - Dennis Melnyk's death

Dennis was the love of my life. His birthdate is Aug 11th 1954
He died Aug 9th 1973
was layed out for his 19th birthday Aug 11th / 73
and was buried Aug 13th / 73

I don't understand how these dates could have gotten mixed up

I have updated the profile for you since both the one who added the profile and the manager of it seem to be abandoned accounts.

Thank you from the bottom of my heart
