How to use investigative statement analysis to examine statements

By examining statements for equivocations and extraneous information, investigators can gain valuable insights


By Stan Burke, P1 Contributor

Investigator Callahan recently responded to a robbery. After arriving at the scene and conducting a preliminary investigation, he interviewed the victim. Specifically, he asked, “What happened?” The victim said:

  1. “I left my work at 11:00 pm. Before leaving I purchased some
  2. cigarettes and locked up the store. I set the alarm, turned out the
  3. lights and locked the doors. The back door was hard to close. I have
  4. talked with owner about having it fixed, but he doesn’t seem to care
  5. about the store like I do. After I was finished closing the store I
  6. started heading home. I walked down Fifth Street and took a right on
  7. C Street. I stopped at a bar, smoked a cigar, shot two
  8. games of pool and drank three beers. After that, I continued with my
  9. walk home. When I was close to my home I thought I
  10.  heard a noise and when I looked around I was somehow pushed or
  11.  grabbed from behind and pulled down to the ground. I believe I was
  12.  knocked out and I guess he then ran away with my money. After
  13.  he ran away, I got back up and checked my pockets. My wallet
  14.  was gone and that really made me mad because it was given to me
  15.  by my brother for my birthday. He bought the wallet when he was
  16.  serving in the military overseas. It was made of leather and had my
  17.  initials stamped on it. That’s about it.”

After reading the victim’s statement, Investigator Callahan questioned its quality. To confirm his suspicion he decided to analyze it using Investigative Statement Analysis.
