Q

Writings/Email

A

Writings can be authenticated via:

o Personal knowledge of the content (ex. yes I prepared this)

o Lay opinion handwriting identification (ex. recognize signature on check is my husband’s signature) - Civilian does not need to be handwriting expert – just need to be familiar with someone else’s writing

  • May have to lay foundation:
    • Ex. seen mom’s signature a hundred times
    • Ex. get check from roommate each month and see her signature each time
  • A non expert’s opinion that handwriting is genuine based on a familiarity with the handwriting
  • And such familiarity was not acquired for purposes of the current case

o Expert opinion handwriting ID

o Distinctive characteristics: The appearance, contents, substance, internal patterns, or other distinctive characteristics of the item, taken together with all the circumstances

Q

Object recognition

A

Photos, X-rays, Computer print outs.

Photos: What you want is anybody to say that photograph accurately represents the crime scene on that date/your car/what it is meant to be a photograph of - anybody can authenticate a photograph

X-rays: You will need the lab tech to testify. Or might recognize limb or something b/c have metal in it, can testify to that.

Computer print outs: Who printed this? What kind of computer is this? This is the program I used. Opposing party has to try to show it is a fraud, etc.
