Bottom line: JA made 3 SEPARATE GAS purchases in SALT LAKE CITY (after the murder) at one gas station: 2 were for around 10 gallons and 1 was for around 5 gallons and SHE THREW OUT THE RECEIPT FOR THE 5 GALLON PURCHASE BUT KEPT THE OTHER TWO RECEIPTS. She was obviously trying to hide the approx. 5 gallon purchase. And if she didn't have that 3rd, 5 gallon gas can, where did she put that extra 5 gallons of gas? Not one receipt for gas shows more than approx. 12-13 gallons of gas purchased in one transaction during her trip, so there is no way the car could hold 15 gallons of gas. Did she dump 5 gallons of gas on the ground? COMMON SENSE.
Also, the defense did not bring up the lie that JA returned the gas can to a different Walmart until closing arguments, so there was no way for JM to then ask any witnesses about existence of other Walmarts in Salinas or returns to other Walmarts. Defense did this on purpose - they could have asked the Walmart witness if other Walmarts existed in 2008, but they wanted to present that possible lie at a time that prosecution couldn't effectively rebut it through witnesses. If it was the truth that JA had returned it to another Walmart, then defense would have asked the Walmart witness about other Walmarts to show that in fact other Walmarts existed, to prove she was telling the truth. They did not do this.
