The remaining 3 have nothing to offer the state, so they will not be making any deals with them. They have Jake and he has given it all up so the other 3 have two choices go to trial or plead guilty. The law is clear on how the deal with Jake was made and all 4 are at present not in line for DP. with it being such an horrific case the state could not (IMO) have reduced the sentence down from LWOP so the only thing Jake could be given in return for his plea was the DP off the table, and he used that bit of leverage to get it removed for all 4.
