Authentication and Identification Flashcards
Authentication as a condition precedent to admissibility requires evidence
sufficient to support a finding that the matter in question is what the proponent claims it to believe

its ability to explain or simulate material facts in the case.
Must assist the trier of fact \+ Fairly and accurately the scene \+ Witness must be substantially familiar with the evidence shown
e.g. maps and charts
Real evidence may be authenticated by:
Testimony from witness about first hand knowledge
Distinctive characteristics:
Chain of custody for fungible items
Must be used with fungible items (all items appear identical—cocaine, pills, blood). Accounting for an item’s whereabouts from the time of issue until trial. Big area for impeachment by defense counsel in criminal cases.
(2) The party entering the item must account for any change in the evidence.
Documents may be authenticated or identified by

(1) custodian: witness must be substantially familiar with the items
(2) one who prepared the document/report (preparer of lab report)
(3) eyewitness to the signing of the document
(4) opinion by expert witness re: handwriting, fingerprints, shoe prints, tire tread marks, ballistics, etc.
(5) by the jury: comparing samples
Three ways to authenticate handwriting
- lay person familiar with the writing (≠preparing for trial)
- comparison by expert
- comparison by trier of fact

A showing that a call was made from an assigned number, proves?
That the call came from the person assigned to a number
