True Murder, with your host, journalist and author, Dan Zupansky.

Good evening, this is your host, Dan Zupansky, for the program True Murder, the most shocking

killers in true crime history, and the authors that have written about them.

Jerry Mark was a Peace Corps volunteer, lawyer, 4-H leader, vice president of his Cedar

Falls High School senior class, and certainly, the most likely to succeed young man when

he graduated in 1960.

In 1976, he was convicted of four execution style murders of his own family.

How could he have done such a thing and why?

The author Scott Coelty, new Jerry Mark from high school, and went on to interview him

in prison, attending the trial and discovering a mind consumed with anger, revenge, jealousy

and greed.

Brothers 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.

The book that we're featuring this evening is Brothers Blood, a heart-land cane and

ablque with my special guest, Scott Coelty.

Welcome to the program and thank you to agreeing for this interview, Scott Coelty.

Thank you, Dan.

Thank you for having me.
