The bodies of Eric and Dylan

I wonder if E&D have gravespots somewhere. MOST mass murderers and serial killers end up getting cremated with the ashes given to a family member or they're buried in an unmarked grave or secret location so that people dont vandalize the grave or memorialize the spot.

I know Dylan was cremated. His family probably has his ashes. I'd only guess the same happened for Eric.

They also could've spread their ashes in a secret location.

I think Eric's parents scattered his ashes out of state if I remember correctly, possibly where they used to live.
Dylan I seem to remember reading somewhere that his ashes were scattered on a trail near their house where they used to go on walks. I could have it wrong

I'm pretty sure that Sue has said she has Dylan's ashes.

Eric's ashes have been scattered.

Is it 100% certain that they were both cremated though? I only know Dylan was because Sue said so.
