I'm sure the DC police have to question the guy again to cover all their bases, (Hmmmm... I can't believe I said DC Police and cover all their bases in the same sentence)!, anyway, I'm in agreement with you and the reporter. This guy that's locked up sounds like a kook but not the kook they're looking for this time around.
As far as the blood, I know forensics are amazing. Don't you think though, that had she been shot, there would be a bullet hole in her clothing? There apparantly isn't one in the skull. And, if she were stabbed there would be a knife slash in the clothing and blood stains. Or had her throat been cut it would have bled terribly and I would think the naked eye could see stains even at this late date. Gruesome I know, sorry!
I don't think the killer wanted any screaming or struggling. This is why I would favor a blow to the base of the skull or strangulation by garrote in the car. Both quick and lethal with little or no bleeding and no traceable weapon.
This is a question from the ozone layer but here goes.
Who found Chandra? Was this turtle hunter identified by name to the publc?
