What is the difference between a resisting, delaying or obstructing a peace officer charge and a murder charge?

^4. True, all charges were not "of the same class." For example, the Pearl Ridge robbery included a resisting, delaying, or obstructing a peace officer charge. These are not the same class of crimes because they share no "common characteristics or attributes." But they are still "connected together in their commission" because the resisting was motivated by a desire to flee and avoid prosecution. (See People v. Valdez (2004) 32 Cal.4th 73, 119 [murder and escape properly joined because connected together by motive "to avoid prosecution."].)
