There are plenty of things that changed just before the murders, those out of the ordinary things that police look for. I had a list on another board but am too lazy to go find it now. For starters though, you have: 1. suicide threat one month before the murders 2. hiring of a maid just two days before the murders after going without one for months 3. bringing all of her jewelry downstairs to show to the maid (to see if the maid knew of anyone who might want to buy it?) 4. Telling the maid she needed to raise $10,000 which was the same amount as the boys' life insurance policies. 5. being on the diet pill Fenphen for too long (she shouldn't have been on it at all) 6. Therapy after the suicide with confusing details (pretty much skated over at the trial) 7. Depression (possibly PPD) 8. Sending Dana home (Dana says it was her idea to go home so there are conflicting stories there) 8. The Jaguar breakdown coupled with the loss of her Pathfinder and her feeling like a caged animal without it 9. Boys dumping out the hottub water, upsetting both parents 10. Darlie and the boys sleeping downstairs with Darin and Drake out of ear shot of the downstairs 11. Them taking the biggest draw they ever had out of the company just a couple of weeks before.
