I don't think that explanation will work though. If he was just using the blank checks he already had, why would he create one on Joey's desktop on the 4th?
None of it works IMO.
To believe him, the jury is going to have to suck up the following:
Saudi Arabia money;
1. Joey asked Chase to create himself a cheque (and delete it) and he already had three blank cheques in his possession to do that before Feb 1st. Two cheques which he printed on 1st for $2500 but never banked (memo line deposit), and one printed on Feb 2nd which he did bank for $2495 - memo line deposit sa 1001.
2. Joey gave Chase two more blank cheques to create for himself on the 4th, one which he backdated printed and deleted on the 5th but didn't bank ($6505 - memo line bal sa 1001) and one he backdated printed and deleted on the 8th which he did bank ($6500 - memo line saudi arabia final).
So that's five blank cheques there just for Saudi Arabia, three of them given to him before Feb 1st (two trashed and one cashed) and two of them supposedly given to him on Feb 4th (one trashed and one banked).
Paul Mitchell money;
3. On the 4th, after giving Chase blank cheques for it at lunch time, Joey supposedly according to DT created a cheque for Chase $4000 memo Paul Mitchell.
4. On the 5th Chase would write a Paul Mitchell cheque not knowing that Joey had created one on his computer the night before.
Plus jury needs to either believe or ignore;
5. Joey would go to the bother of creating a cheque but not bother printing it.
6. Joey would be murdered when that cheque on the 4th was created but his murder is not connected to the cheques.
7. The murder is personal and it is someone who was right up close to Joey, within an arm's reach with this short hammer, in his personal space, and he didn't know it was coming - took no steps to run away, but the murderer didn't just leave the bodies in the house to let the world know they had been murdered, the fact of the murders had to be hidden, which adds to the murderer's profile as being someone who would be connected immediately.
8. Metro calling and emailing Joey on the 5th, might well raise the alarm about Joey being missing would be paid cheques and stop calling Joey. Who created the cheques for Metro? Chase. Such bad luck.
9. Chase would create cheques the next day backdated to the date of Joey's murder, not knowing he's been murdered, making that date a highly significant and sensitive issue to the writer.
10. Joey would not give Chase a cheque on the 2nd for Saudi Arabia but would give him a cheque for $100, knowing he already had three blanks, and Chase would drive all the way to Fallbrook and back on 2nd just to get that $100.
11. Joey would not follow his usual practice of issuing cheques to Chase that week.
12. Joey would send Chase an email on Feb 1st saying Chase owes him $42845, and not include the Saudi Arabia money as deductible or payable yet.
13. Chase would not mention the $ he had paid himself to detectives when he showed them the email. He says Joey owed him after those projects but since he's already paid himself he's not owed anything when they talk to him.
14. Joey would give blank cheque stock to Chase or tell him to sign his cheques, knowing he is financially reckless, has prior convictions, has had to pay money to help Cathy before, and is not working as expected but is in the casinos.
15. Cheque stock is missing and it's pure coincidence that Chase was writing and printing his own cheques somewhere other than on Joey's computers.
16. There is zero evidence that Joey met Chase at lunch on the 4th. There is however a bit of a panic on Chase's end as he makes 13 calls in 9 minutes. And if that meeting is unproven then not only did Chase not get more blank cheques from Joey that day he didn't touch his hand either.
17. Joey just happened to coincidentally call his bank, log into QB must have been to look at something else in his books as he's driving, and then call his bank again on his way to Rancho Cucamonga, but it's unconnected to the murder or the cheque that cleared on the 4th.
18. Chase has never had an alibi for the 4th but now his memory has improved and he can tell Cathy where she was and where he was, even though they wracked their brains together over this for years, she saw a call on his phone that never came in and then called his phone knowing it was on the counter, while she's also at school and he's at the movies.
19. Phone pings where the bodies were buried.
20. No calls to Joey that Saturday, one on Sunday and none on Monday morning when he's telling Carmen he hasn't been able to get hold of Joey.
21. Chase calls Susan Blake the day after the Trooper went to San Ysidro.
22. Chase's bank account shows balances far higher than he's had before, looking back over the prior year. Joey got generous when he was murdered.
Of course all this can be explained by confirmation bias.
