[Spider-Man] How did Sandman know that Green Goblin was impaled with his own glider but Harry Osborn didn't?

"They both died fighting Spider-Man. It was all over the news, Green Goblin impaled by the glider he flew around on and then a couple years later, you, Doc Ock drowned in the river with your machine ."

But it took another few years after Normans death for Harry to find out how he died when the bulter told him. So how come everyone else knew except Harry? Was the rest of the world in on Norman's whole "Don't tell Harry"?

Sandman seems to have come back from 2024 as Raimi Peter did. It’s more like that the truth of the Osborn’s and Goblin’s was revealed in the aftermath of Harry’s death, after he died fighting against Sandman and Venom unmasked with hundreds watching and Bernard and Peter no longer having any reason to hide it. There isn’t any other reason why anyone would have known how the Goblin died beforehand when Peter would have been very invested in keeping it all a secret, and we can imagine the military would have been sniffing around Oscorp during 2&3 to know what was happening if so.
