Two answers here, one IIRC, I think her body was found around 3 miles from their residence.
As for the money, many of us are referring to the time frame of 6:00 a.m. Saturday morning. Why didn't Brad swing by the ATM on one of his trips to/from Harris Teeter? He was busy surfing the web, supposedly, yet he didn't get Nancy's allowance she wanted? He did all this cleaning to make her happy, laundry, but the one thing even Brad said 'nancy was pissed about was him not giving her, her allowance on Friday.' So why then, once the girls were up and fed, didn't Brad load 'em into the car and swing by the ATM? Why, on Brad's way to look for Nancy, didn't he get the allowance money? He never thought about getting her that allowance money because by that time he KNEW she was dead and wouldn't be needing it anymore. MOO. If I knew my husband was mad because I forgot to pick up his dry cleaning, I wouldn't be cleaning out his garage for him, I'd be high-tailing it to the cleaners to pick up his suits. Just a hypothetical to demonstrate the futility of trying to appease your angry spouse, but not attempting to do the thing they are most angry about.
