The former IRS law enforcement officer-turned-defendant in an aggravated murder trial continued his testimony about what happened the day his wife, Christine Banfield, and Joseph Ryan were killed. Banfield recounted the terror he said he felt while seeing Ryan, his wife, a knife and blood in his bedroom. “I don’t know that I’ve ever been more panicked in my life,” Banfield testified. And Juliana Peres Magalhães, the family’s au pair and his romantic partner, also shot the man moments later, he testified. One of those witnesses included Brendan Miller, a digital forensics examiner at the department who concluded that there was no indication that Christine Banfield lost control of her devices before the slayings.
