Jerry Mark was a Peace Corps volunteer, lawyer, 4-H leader, vice-president of his Cedar Falls High School senior class and certainly a most likely-to-succeed young man when he graduated in 1960. In 1976 he was convicted of 4 execution-style murders of his own family. How could he have done such a thing and why? Author Scott Cawelti knew Jerry Mark from high school and when on to interview him in prison, attending the trial and discovering a mind consumed with anger, revenge, jealousy and greed. Brother's Blood chronicles the killer's cross-country motorcycle ride, the landmark investigation and arrest, the circumstantial case at trial and the appeals that continued for 30 years.
