I think that when Nancy returned from Hilton Head, after being lovingly supported by her family, after telling them all about how unhappy she was, after being given lots of advise and encouragement to take the next big step (leaving the house with her children); I believe Nancy returned to Cary with a new mindset and attitude. I believe she became empowered. Brad had to see this immediately, knew things were definitely at a head. He probably started facing how his plans were getting all messed up, short term and medium term goals were going up in smoke. He probably had been brooding for a few days. The reality of the mess he had made of their marriage was sitting on a plate in front of him like steaming poo.
I do think that with Nancy's new attitude, she started verbalizing and showing her strength and will. He knew it was about over. She probably was looking for another place to live and her friends were helping her. I'd expect her family pledged money to help her do this.
I have wondered if she struck the first blow? Threw something? Threw several things? I hope LE compare pictures of the inside of the home before and after to see what heavy object could have DNA on it, or is missing or damaged. It is probably an object that was close and easy to grab. I imagine she was killed within a few minutes of returning home. That's my theory...
I have to say your theory is very close to mine.
I will add I do not feel it was premeditated. If he thought it thru he would have taken her to Regency where she was known to jog. There is so much construction going on near the lake and so much wooded land he could have made this look like a random act that occured while she jogged.
I don't believe she walked in on him Friday nite since she was 100' from her own front door.
The break ins occuring around the area have been coming in spurts for the past 3 yrs. Purses, laptops, GPS's are the items they are looking for. The ones committing these crimes are supposedly only doing cars that are unlocked and in the early morning hrs before daylight.
At first I wondered if Nancy came home from the party to see someone in her car, confronted them, it turned to violence. But, Brad told what she was wearing to go jogging and at what time. So my theory is gone regarding a thief.
My kids are always going to the lake to walk, meet friends at the pier, or to swim. There is just no alert going on as it would be if this were a random act. I have to say that speaks volume.
Lochmere is a huge subdivision. It contains approx. 1400 homes. Pools, lakes, tennis courts, jogging trails, woods, etc. Just imagine all the females and children living there if there is danger lurking and not being alerted.
So my theory is this....IMO Brad is involved. He blew when she came in Friday nite. She finally stood up to him with her new found energy and encouragement from her family. He was not prepared for this at all.
He was already furious because of the call he received at home when Adams called looking for NC, casually mentioned painting Sat. Brad didn't know about the painting and realized he had the girls Friday nite, Sat morning and now Sat afternoon. This would encroach on his time and plans! Nancy had a glass of wine at the party, said some things that angered him further, triggering a physical reaction.
My reason behind this is...what friend needs to call at 10:30pm to confirm painting for 2pm the next day? One that has concern because of a certain tone, or a statement said when she called earlier that evening. She tossed it around to tell NC or not, and decided to call Nancy so she could be prepared for an angry Brad. This call was not about a flight out of RDU at 6am which would warrant the call. Nancy is an early riser and this friend had to know she could confirm painting early Sat morning.
I feel Adams is the link to all this, especially because of her call to NC and to the police.
