Six pairs of people in this archive killed together. In each pair, one of them gave evidence against the other and received a lesser sentence for it. The sentences inside those pairs differ enormously, and the thing that determined which of the two got the lighter one was not who had done less. It was who talked first.
Roy Norris and Lawrence Bittaker abducted and killed five teenage girls in California in 1979. Norris agreed to plead guilty and testify in exchange for avoiding the death penalty. He received forty-five years to life and died in prison in 2020. Bittaker was sentenced to death in March 1981 and spent thirty-eight years on death row before dying of natural causes.
Kenneth Bianchi and Angelo Buono killed ten women and girls in Los Angeles as the Hillside Stranglers. Bianchi pleaded guilty and testified against Buono in exchange for avoiding the death penalty; the entry records that he was a poor and evasive witness. He is serving life in California and Washington. Buono was convicted in 1983 and given life without parole, and died in prison in 2002.
Charlene Gallego took a plea and testified against her husband Gerald. She served sixteen years and was released in 1997. He was sentenced to death in California in 1983 and again in Nevada in 1984, and died of rectal cancer in a Nevada prison medical facility in 2002.
Catherine Wood and Gwendolyn Graham, nurse's aides at a Michigan care home, smothered five elderly patients in 1987. Wood eventually told her ex-husband and pleaded to second degree murder and conspiracy in exchange for testifying. She was sentenced to twenty to forty years, served thirty-two, and was released on parole in 2020. Graham was convicted of five counts of first degree murder and is serving life without parole.
Kenneth Kimes testified against his mother Sante in the Kazdin case in exchange for avoiding a death sentence. Both received life sentences in California in 2004. This is the one pair where the deal did not open a gap: she was already serving 125 years in New York for the murder of Irene Silverman, obtained without a body, and she died in prison.
Then there is the case that made the argument public.
Karla Homolka pleaded guilty in May 1993 to two counts of manslaughter and was sentenced to twelve years, in exchange for testifying against Paul Bernardo. She served the full sentence and was released without parole in July 2005. Bernardo was sentenced to twenty-five years in September 1995 and later declared a dangerous offender, which makes release unlikely.
The Homolka agreement was reached on the understanding that she had been a battered woman coerced by a violent husband. Videotape evidence recovered afterwards showed a more active participation than the plea had assumed, by which point the deal was done and could not be undone. It became known across Canada as the deal with the devil, and it produced a formal judicial review, the Campbell inquiry, into how the police and prosecution had handled it.
What the six pairs show is a structural feature rather than six separate failures. Where two people have killed together and the case against both is weak without one of them, the state has to buy testimony, and the only currency is a sentence. The first to offer sets the price.
That produces outcomes that cannot be defended as proportionate. Charlene Gallego was free after sixteen years while Gerald sat under two death sentences. Catherine Wood was released in 2020 while Gwendolyn Graham will die in prison. Norris avoided the death penalty and Bittaker did not.
Read alongside the four sets of brothers in this archive, who did comparable things and received sentences that were not comparable at all, and alongside Nathaniel Cook, who admitted a part in three murders and walked out under an agreement while his brother remained inside, the pattern is the same one from a third direction. The sentence records what the state needed at the time. It is not a measurement of the person.
