Huron South Dakota Bombing 1971

In 1971, a bombing in Huron, South Dakota brought unexpected attention to two brothers whose lives had unfolded largely out of public view.

Lloyd Jerome Brenna and Wallace Woodrow Brenna were not widely known figures, yet the events surrounding the bombing would place them at the center of a complex and unusual criminal case that spanned multiple states and decades.

The story and the events surrounding the bombing will be released as a five-part serial podcast titled The Bagpiper and His Brother on May 7, 2026. The series, by Dakota Spotlight, examines the events in detail through meticulous research and original reporting.

The Brenna Brothers

Lloyd and Wallace Brenna were born in North Dakota and experienced early instability following the death of their mother and the separation of their family. As children, they were placed among relatives and institutions, with parts of their upbringing unfolding in different regions, including Wisconsin and Chicago.

As they grew older, patterns of behavior began to emerge that would eventually connect the brothers to a series of criminal activities — including an alleged attempt on the life of a federal employee — culminating in the events of 1971.
