Othram DNA Tech Aids Madison County Cold Case, Charges Suspect

Investigators from Madison County Sheriff's Office solved a cold case from 1993 using new DNA technology. Randy Gail Sperino was found murdered in Illinois, with no matches in standard DNA databases for decades. Detectives sent genetic evidence to Othram, a Houston-based company specializing in investigative genetic genealogy. This technique identifies distant relatives through DNA data from commercial ancestry databases. Using this, they identified a male family member, leading to Albert "Buddy" Zigler, 70, who confessed and was charged in May 2024. In addition to DNA technology, detectives used Centerline AI software to analyze over 2,000 pages of case records. The AI helped reconstruct timelines and organize witness information, streamlining the investigation process. The use of investigative genetic genealogy combined with AI-assisted evidence analysis demonstrates how advanced technologies can resolve decades-old cases and provide closure to victims' families, impacting how law enforcement approaches cold cases going forward.
