Convictions for first degree murder are affirmed in part, reversed in part, and remanded where: 1) defendants' challenges to the sufficiency of the evidence were rejected; 2) defendants failed to show a clear abuse of trial court's discretion; 3) defendant failed to show a reasonable likelihood that the jury applied the trial court instruction in a way that denied fundamental fairness; 4) section 1203.1l emergency medical services restitution fines, which the statute authorized solely "as a condition of probation," was stricken from the judgment since neither defendant received a grant of probation; 5) there was no basis for reversal of the judgments on the basis of cumulative error; 6) defendant failed to show either an actual conflict that adversely affected counsel's performance or informed speculation with a factual basis in the record about a potential conflict that adversely affected counsel's performance and an abuse of discretion by the trial court in denying his or her motion to disqualify counsel; and 7) denial of defendant's Marsden motion as "not timely" was an error.
