Begin your citation with the last name of the witness. For example:
Thompson
Follow the last name of the witness with the type of resource you are citing. In Bluebook style, abbreviations should be used. The Bluebook abbreviation for deposition is "Dep."
Conclude your citation with the page number you are referencing, followed by a period.
Place parentheses around your citation. It should appear as follows:
(Thompson Dep. 9.)
Position your citation directly after the passage you are citing, not within the sentence. For example:
Under sworn testimony, the witness alleges that there were "between 15 and 17" assailants, and that all carried weapons. (Thompson Dep. 9.)
