So, the interrogation plan was for the 1st guy to go in and talk to EAR about the Sacramento murders and then Holes was going to go in and talk to EAR about the other Northern California cases. Holes didn't get his chance because the plan was interrupted to bring the Southern California homicide detectives (of GSK cases)into it beforehand.

Ergo, EAR interrupted the plan by refusing to talk without a global deal settling all the DP cases beforehand for LWOP plea agreements. By the time the S. Cal cops got to Sacramento, 4-6 hours later, they all decide that to seal the LWOP deal in exchange for EAR talking EAR lawyers up to handle the whole mess.
