When a defendant is arrested on an arrest warrant from another county for a crime committed in that other county, is the police officer's statement that they would "try to explain the whole thing" to that other agency?

Similarly, in People v. Carrington, supra, 47 Cal.4th 145, the defendant was arrested on a burglary warrant from another county. While in custody, officers questioned the defendant regarding a homicide in their county. During the interrogation, an officer stated they "'would try to explain this whole thing'" to the other agency "'as [best] we can'" if the defendant cooperated in the interview. However, he also noted he had no control over the other agency. The court found the statement was not an express or implied promise of leniency. (Id. at pp. 169-170.) Instead, the court found the statements, taken in context, only relayed that the officer would try to get more information about the out-of-county burglary to assist the defendant regarding her status for that crime. (Id. at p. 170.)
