This is the partial banking records they are attempting to put in, instead of a complete picture.
We have records here on WS that Raven's ebay account was still active and he was still selling stolen goods after his initial arrest and he lost his job from Eurosports up until the time of Janet's murder.
So though they got a break on their rental, though he was pawning things, they didn't have to pay for ANY groceries for three months prior (I spent like $200 a week or more and that's without baby formula & diapers) they still had some disposable income, the issue is he would have had ZERO income come May because he knew at the beginning of April he was going to lose his job and he knew he wasn't going to get the job in Washington because because of the EMBEZZLEMENT (the fight with the soccer ref) was well, what it was, but the embezzlement hadn't even shown up on his record then, so just imagine how much crap he would be in after that came out.
He knew he couldn't get a productive job again.
Raven was was getting rid of things, and attempting to make it look like someone broke in and stole things, he was probably trying to get rid of the TV to say that someone stole it but got caught by the Home teacher.
The painting on the wall was on the floor, so maybe he had plans to get rid of that as well. Perhaps Janet did have her rings on when he stabbed her and he took them off and washed the blood off them and forgot to pocket them as well, who knows, he didn't forget to take her cell phone though!!!
All speculation but it all points more to the fact there was PLENTY of motive, plenty of opportunity, plenty of means to do this.
