Deaver was fired from the SBI in January 2011, after an independent audit of the agency found he had falsely represented evidence in 34 cases, including withholding negative results in the case of Greg Taylor, a North Carolina man who spent 17 years in prison on a murder conviction based on Deaver's testimony.[25] A bloodstain-analysis team that Deaver had trained was suspended and disbanded. In the 2003 Peterson trial, Deaver testified that he had been mentored by SBI bloodstain specialist David Spittle, had worked 500 bloodstain cases, written 200 reports, and testified in 60 cases. During the retrial hearing, SBI Assistant Director Eric Hooks testified that Deaver had written only 47 reports. SBI agent David Spittle testified that he could not recall mentoring Deaver who, since completing a two-day training course in the 1980s, had testified in only four cases, the Peterson case being the third. The SBI cited the bloodstain analysis given in the fourth case as the reason for firing Deaver.[26]
On December 16, 2011, Peterson was released from the Durham County jail on $300,000 bail and placed under house arrest with a tracking anklet. His release on bond followed a judicial order for a new trial after Judge Hudson found that SBI blood analyst Duane Deaver had given "materially misleading" and "deliberately false" testimony about bloodstain evidence, and had exaggerated his training, experience, and expertise. Former North Carolina Attorney General Rufus Edmisten said that any evidence gathered after Deaver arrived at the scene might be deemed inadmissible in a new trial.[30]
In July 2014, Peterson's bond restrictions were eased.[31] On February 24, 2017, Peterson entered an Alford Plea to the voluntary manslaughter of Kathleen Peterson.[33] The judge sentenced him to a maximum of 86 months in prison, with credit for time previously served. Because Peterson had already served more time than the sentence, he did not face additional prison time. His plea was an Alford plea, meaning he did not admit guilt, but acknowledged the state had sufficient evidence to convict.
