question

A defendant is on trial for possession of heroin. During the prosecution's case-in-chief, a police officer testifies that he watched another officer seize a bag of white powder from the defendant and seal it in an envelope, which both officers initialed and dated and then placed in the police property room. The prosecutor then calls a chemist to testify that she obtained, intact from the property room, the dated, sealed envelope with the initials of both police officers, whose handwriting she recognized police officers, whose handwriting she recognized from previous experience, and that testing disclosed that the powder therein was heroin. The defendant argues that the prosecutor has not sufficiently authenticated the powder tested by the chemist as the powder that was seized from the defendant. Is the chemist's testimony admissible?

options

  1. No, unless the envelope and powder are produced in court or their absence is explained.
  2. Yes, because the chemist's recognition of the officers' handwriting is sufficient authentication.
  3. No, because the chemist did not personally witness the seizure of the powder.
  4. No, because the chemist did not directly receive the envelope from the police officers.
  5. Yes, because the powder is sufficiently identified as having come from the defendant.
  6. Yes, because an object in official custody is self-authenticating.
  7. Yes, because the envelope was properly sealed and initialed by the officers.
  8. No, because the chemist lacks firsthand knowledge that the powder came from the defendant.
  9. No, because there is no proof that the powder in the envelope is the same powder that was seized.
