Killing Cousins

After an investigation spanning nearly two years, Los Angeles investigators come up empty in the case of a terrifying serial sex killer.

But then, a seemingly unrelated arrest is made across state lines. In book two of Murder by Increments, we journey deeper into the life and mind of the suspect at the center of the case: one of the most confounding and mysterious serial killers in American history.

Killing Cousins documents the shocking story of an abusive childhood that created a monster, and the suspect’s possible involvement in a separate string of killings of teenagers in Rochester, New York.

Was this man truly a multiple personality, or a cunning sociopath enacting a daring hoax against the criminal justice system? By the end, you will be able to make up your own mind.
