I didn't think there were witnesses willing to share this with the
Daily Prophet? Or were they?

Carol chimes in:

Okay, I'm just going to ask a simple question. (I have my own theories
regarding DD and Snape, which I'm not going to bring in here.)

How did anyone from, say, the Ministry or the Daily Prophet, know that
Voldemort had killed the Potters and then vanished rather than being
killed himself? 

Hagrid was not an eyewitness to their deaths, even if he had time to
talk to anybody, and could not report exactly what happened even if he
was on the scene when the Aurors and reporters arrived. Harry, who had
a vocabluary of perhaps a dozen words at the time, would be even less
help. Sirius Black wasn't talking--he was in pursuit of Peter
Pettigrew--and he (Black) wasn't present at the Potters' deaths,
either. Pettigrew, the probable eyewitness, probably wasn't talking,
considering that he would implicate himself if he wasn't extremely
careful. 

So what did the Aurors find? Were there identifiable bits of Voldemort
lying around? (They didn't get his wand; Wormtail seems to have hidden
that and retrieved it later.) If so, wouldn't he have been pronounced
dead (wrongly, as it turns out)? And if no bits of him were found,
what proof was there that Voldemort did it and that he was vaporized? 

All we have is two presumably unmarked bodies, an exploded house, and
a living toddler with a lightning-bolt-shaped cut on his forehead. And
if Hagrid got Harry away before the Aurors and reporters (and Muggles)
arrived, how did the Daily Prophet even know about the Boy Who Lived,
whose scar was caused by a deflected AK that ought to have killed him?

Not so simple after all, even setting aside how and by what means
Dumbledore knew that the Potters were under attack, which is, IMO, a
separate question. At any rate, I think maybe DD was more responsible
than Hagrid for spreading the story, which would account in part for
the missing twenty-four hours. 

Carol, hoping for satisfactory answers in DH to what now looks to her
like a giant plothole
