This audio is from Day 7 (March 12, 2015) of the trial of Jonathan Broyhill, 31, for assault with a deadly weapon with intent to kill after he stabbed young Democratic strategist Jamie Kirk Hahn and her husband, Nation, 27, at their North Raleigh residence in Raleigh, North Carolina in April 2013. Jamie, 29, sustained fatal stab wounds to her abdomen; Nation recovered.

On the stand, Nation Hahn is being cross-examined about the day of the murder by defense attorney Joseph Arbour. We learn that Broyhill was known as a longtime friend of the couple. He and Nation Hahn grew up in the same town and Broyhill was the best man at the Hahns’ wedding in 2009. Since at least 2010, Broyhill worked for Jamie’s policy firm, Sky Blue Strategies.

Brad Miller (D-NC) had worked with both Jamie and Broyhill through Sky Blue Strategies in 2012 on his reelection campaign, which he ultimately abandoned. Miller’s campaign had been independently investigating Broyhill for alleged campaign-finance irregularities. We learn that Broyhill had been lying about the fact that he had cancer, and stealing money from the Miller campaign. The attack on the Hahns, we learn, came from a confrontation about the money.

Nation Hahn maintains his composure on the stand, although Arbour’s chummy tone clearly grates on his nerves. He responds to most questions with a “yes, sir,” “no, sir,” or “I can’t recall, sir,” remaining dignified even when being questioned about taking his iPad to the bathroom with him, or whether or not his pants were down or up when he heard Jamie scream. His poise and self-possession make Arbour sound like a chump. Broyhill was convicted, and is serving a life sentence in prison.
