Perales v. United States

How later courts describe this case

• noting that failure by defense counsel to indicate the defendant could not assist in her defense or understand proceedings was “substantial evidence” of competency
• upholding district court’s denial of motion to suppress unwarned statement where defendant “failed to establish that when she made the Statements she was in custody or that she had invoked her right not to be questioned except in the presence of her counsel”
• it is harmless error when a co-defendant’s statements implicating defendant is elicited at the trial because the evidence of the defendant’s guilt is overwhelming and the statements did not contribute to the verdict beyond a reasonable doubt
