On Thursday AM this was reported after the Greta show. I believe Geragos called Rocha's attorney Wednesday night after seeing the show. He said they could go in on 6/3 and didn't say a word about only taking three items. He sprung that on them the next day along with the autopsy blindside. That resulted in the argument and the ultimate breakdown between the parties.
Now where is your source stating they had a deal prior to the show?

Defense lawyer Mark Geragos says he has worked out an agreement to let Laci Peterson's family visit the house and remove her journals, a food processor and a watering can that said "Laci's Garden."
