Q

What is the point of establishing chain of custody?

A
  • Chain of custody - commonly for undistinguishable items; witness(es) can testify to where item was from the moment that mattered to the moment when offered.
    o EXAMPLE: Drugs are offered in a criminal prosecution. Officer can testify to personally seizing drugs (or seeing the seizure), placing them in and sealing a bag, delivering them to the police department’s Evidence Control Unit, picking them up the morning of trial, and opening them in court.
  • Chain of custody also serves to confirm that the item of tangible evidence is in “substantially similar condition” in which the witness found it; this confirms it was not tampered with or materially altered.

Q

How can authentication be done through distinctive characteristics?

A
  • Other distinctive characteristics - distinctive appearance, contents, substance, internal patterns, etc.

Q

How can handwriting be authenticated?

A
  • By a layperson with familiarity (NOT acquired for litigation);
    o EXAMPLE: W can authenticate letter as defendant’s as they’ve been pen-pals for years.
  • By comparison by an expert with person’s known writing sample; or
  • By comparison by the trier of fact - this is unique!
    o EXAMPLE: If W claims letter was written by defendant, it can be submitted to the jury who can compare it themselves and if they believe by a POTE, it is the defendant, it is deemed authenticated.
