Bates v. United States, 51 A.3d 501

Appellant Donald Bates was convicted by a jury of three counts of robbery and one count of credit card fraud, arising from two purse snatchings in March 2006 and a third purse snatching plus credit card fraud in September 2007.
The 2006 robberies involved a getaway car linked by license BX-5228 and the car was later found registered to Bates’s mother; items from victims were recovered in or near Bates’s vehicle.
The 2007 robbery also involved BX-5228; a victim identified Bates from a photo array and in person, and one stolen credit card was used at a gas station on the date of the robbery.
Bates moved for severance of the 2006 charges, arguing prejudice from joinder with the 2007 charges; the trial court denied, concluding identity evidence from 2007 would help prove Bates’s identity for 2006.
Bates also moved to suppress admissions made to police on March 12, 2006 without Miranda warnings, contending custody was present; the district court denied, finding non-custodial interrogation.
The Court of Appeals upheld the denial of severance and suppression, and affirmed the remaining convictions after rejecting Bates’s other challenges.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether severance was required for the 2006 charges	Bates argues severance would prevent prejudice from the 2007 robbery evidence.	Bates contends joinder prejudices his defense to 2006 charges.	No abuse of discretion; admissible identity evidence outweighed prejudice.
Whether admissions to police on March 12, 2006 were Miranda-violative	Bates claims custodial interrogation without warnings.	State argues no custody; interrogation was consensual.	Miranda warnings not required; interrogation not custodial under standards.
Whether sufficient evidence identified Bates as participant in 2006 robberies	Prosecution showed Bates used the getaway car and possession of evidence.	Defense challenged inference from other-crimes evidence.	Sufficient evidence; circumstantial links and 2007 identification support identity.
Whether the aiding-and-abetting instructions were plain error	Instructions did not expressly require same mens rea for aider and abettor.	Lack of explicit mens rea instruction not plain error.	No plain error; the instruction properly conveyed required mens rea.
Whether the court’s response to jury's credit card fraud note was error	Note required further guidance on aiding-and-abetting for the 2007 charge.	Supplemental instruction clarified law.	Appropriate, no error.
