Officials investigating the deaths of two prosecutors in rural Texas have turned their attention to a former local official who threatened the two victims after losing his job in a corruption investigation, the Los Angeles Times reports. The man who emerged as a person of interest this week was convicted and placed on probation for stealing public property in Kaufman County two years ago. After his arrest, investigators found he had numerous guns, including an assault rifle and survivalist equipment. The attorney for the person of interest said he had “strenuously denied making any threats.” After the killing of District Attorney Mike McLelland last weekend, Brandi Fernandez is acting district attorney for Kaufman County. Texas Gov. Rick Perry is expected to name a permanent replacement soon.
