@ Sustained: Your calculations are correct. There is at least 300 miles unaccounted for and several hours. She was ordering at an In N Out in Sparks, NV at 10:43 AM on 6-6. 26 hours later, she is putting gas in the car in Redding, CA. Then a little less than an hour after that she return the car. She was scheduled to turn it in at 9:30 AM. If she was 3-4 hours away on 6-6, why was she unable to tuen the car in on time? What did she do or where did she go in that missing 26 hours?
Looking at the receipts a couple of things jumped out at me:
1) She ordered two meals 5 minutes apart at In N Out starting at 10:38 AM. 5 minutes isn't a long time from the end of one purchase to the end of the next if you consider that the food had to be prepared, she had to eat it, she had to get back in line, and she had to re-order. One of In N Out's selling points is the freshly cooked hamburgers they serve. When was the last time you ate a hamburger in 5 minutes and did not look like a ravenous dog doing it. 5 minutes is about the right amount of time to finish putting gas in the car and walk across the street to the In N Out. The gas transaction started at 10:34 Am and she had made the first order at 10:38 AM. Most pay at the pumps have you swipe your card prior to filling up, so the time stamp would be at that point.
2) Who uses multiple transactions to fill their car up or fill the car and cans? Most people do it all in one transaction. When did she fill the cans up? None of the transactions seem to support an extra 10-15 gallons of gas being purchased. No where she bought gas was significantly different in price, with the exception of Sparks which was 4.99 a gallon. Everywhere else was within $0.30 of each other. For that savings on 20 gallons, who would want the headache (fumes) of having cans in the car or the worry that they might spill in the rental car?
3) Her times don't add up. She drove from SLC to Sparks (525 miles) in about 6.5 hours. That is an average of 80-81 mph. She drove from Pasadena to Mesa in 7 hours, a trip according to MapQuest that should take almost exactly 6 hours (she would have averaged about 54-55 mph). One would assume that she had traveld from/to Mesa before, so she should not get lost on that portion of the trip. So, that is 1 hour, Pasadena to Mesa, and 26 hours, Sparks to Redding, unaccounted for. Travis was killed between 5-6 PM, 16-17 hours later she shows up in Utah (36 hours later than she lead Burns to believe she would be there. The trip is roughly 11 hours by MapQuest. That is 5-6 hours unaccounted for. She had to sleep at some point, but where did she sleep?
Those are just a few questions from a quick glance at the receipts.
