Most of the letters in Series I are from David Berkowitz, the Son of Sam serial killer. Written while incarcerated in Attica, Berkowitz corresponded regularly with Abrahamsen over a two year period. Much of the subject matter consists of Berkowitz trying to self-analyze about why he committed crimes. Abrahamsen continuously asked questions about Berkowitz's family, his upbringing, and his relationships with other people. There are a few letters from Jessamyn West, a distant relative of Nixon who assisted Abrahamsen while he was working on his book Nixon vs. Nixon.
