Re: NK. I've done some fairly extensive looking into him. Here's what I think may be pertinent:
First of all, I believe he has changed residences since MH's disappearance. I looked him up when this first broke and recall he was listed living quite near JPJ. Now he's a ways away.
He starts the detailed time reporting of his activities only one or two reports prior to the 10/17 one, but this is not the first.
A few things about his reports:
On the October 17th trip, he reported 3 hours exactly as travel time from Charlottesville to Alexandria on 10/17, to cover 171 miles. That’s almost 60 mph with no stops, faster if he stopped. On the way back to Richmond, 102 miles in 2:08, arriving at 6:08. That's a reasonable 50 or so MPH.
If he then drove back to Charlottesville (70 miles), he would have been in the vicinity before MH disappeared.
On 10/22, according to his figures, he averaged 65 MPH to Newport News and 55 MPH on the return. On 10/29, according to his figures, he averaged 57 MPH overall to Chesterfield, south of Richmond, 65 MPH on I-64 and 44 MPH after turning off I-64 (stay with me here).
What jumped out at me are some possible inaccuracies he had in his November 6th entry, his last.
NK says it’s a 72 mile drive, but it's actually 98.2 miles from Kane Furniture to Lake Braddock High School in Burke, Virginia (108 circling through Reva). Suggested to have taken 2:49 (this makes the suggestion work out to 35 MPH), actually reported by NK at 3:16, but he reports at least 3 stops (7-11, Reva, Sheetz). Covering 98.2 miles in 3:16 is a 30 MPH average, and to cover his reported distance of 72 miles in 3:16 would work out to only 22 MPH!
Kane Furniture to Reva is 41.1 miles, estimated at 1:14, or 33 MPH. He says it took him from 1:48 p.m. to 3:06 p.m. including the stop at the Reva, Virginia gas station/post office convenience station. That’s 1:18, so about a four minute stop fits that.
Here’s where it gets interesting…he says 11 minutes later, at 3:17 p.m. he passed Eastern View High School, a new school just off 29-N at State Route 666. But that’s 13.2 miles, which he says he did in 11 minutes??? That would be 72 MPH.
He passed George Washington University at 4:34, one hour and 17 minutes after Eastern View High School. Another 53.2 miles in 1:17 (estimated at 1:19), 41 MPH.
Another 4.4 miles to Hunan West in Springfield, covered in 20 minutes…driving around deciding on dinner place? 1.2 miles to Lake Braddock high school.
The high school is 67.2 miles past Reva, estimated at 1:46. He says he covered all but about 4 miles of it from 3:06 to 4:34, 88 minutes. 63.2 miles in 88 minutes is a reasonable 43.2 MPH. But if we assume that 13.2 of those miles were covered in 11 minutes, that would leave 54 miles in 1:35...34 MPH.
I have driven 29-N and 66-E a lot before, and nobody averages in the 30's unless they are stopping to shop for antiques, eat, whatever...29 is 55 or 60, four lane highway from the outskirts of Charlottesville for 90 minutes where you pick up 66 (with some traffic lights on 29, but very few traffic snarls).
So, either he was driving really slowly that day, he was stopping a lot, or he didn't actually make that trip and made up a time line that fit what Google maps said it would take, give or take a few minutes, without considering that to do so would be driving much slower than the speed limit.
Thoughts? Sorry for the long post...
