C ' FACTUAL BACKGROUND The Tarasoffs claim to remember translating and transcribing at least 2 conversations involving Oswald. They remember that the first one was fairly short and routine. Oswald did not identify himself in this first conver- sation. The second one was much longer and Oswald did identity himself ~ in this conversation. The Tarasoffs remember Oswald discussing his finan- cial situation in this call. They deny making any editorial or marginal comments in the transcription of this call. The Tarasoffs remember nothing unusual about the first call or the circumstances around its delivery or transcription. The second call was” delivered to them and they were asked to transcribe the Oswald call as quickly as possible. Their contact expressed a strong interest in the ; identity of the caller and the substance of the call. The Tarasoffs C translated and transcribed the call and returned the transcript on the ~ same day, using an emergency contact as opposed to waiting until the next morning and using their standard contact. | It is not clear whether or not the Tarasoffs have any independent memory. of any other calls involving Oswald. oe Exhibits are classified and will be added‘ at a later date. Questions based on these exhibits will be asked.
