Why Were Two People Arrested in Alexandra Alston’s Augusta Case, According to Authorities?

 In Augusta’s Harrisburg community, the sudden death of 56-year-old Alexandra Alston left investigators searching for answers before a fast-moving trail led beyond Georgia, turning a quiet neighborhood into the center of a homicide investigation. Alston was found unresponsive inside her home late Friday, Sept. 25, and authorities soon began looking for a man seen in the neighborhood who might help explain what happened.

Richmond County deputies responded to the 1900 block of Watkins Street after receiving a report of a suspicious situation late at about 11:03 p.m. When they arrived, Alston had suffered injuries and was unresponsive; officials said she was pronounced dead at 12:28 a.m. An autopsy was scheduled as investigators worked to establish the circumstances surrounding her death, while detectives began piecing together the final hours of Alston’s life that night, as investigators began documenting the scene. 

Attention quickly turned to a man reportedly seen going door to door in the Harrisburg area, apparently soliciting employment. Investigators described him as wearing an orange hooded shirt, gray pants, brown work boots and sunglasses, while carrying a clipboard; he also had long, dark hair and a full beard. At that stage, deputies were asking residents to review security footage and help identify the person they wanted to question and clarify his movements through the neighborhood that day.

The investigation developed into an arrest case involving Osiel Delgadillo Noriega, 36, and his wife, Sully Delgadillo, 39, both identified as South Carolina residents. According to authorities, Noriega faces a murder charge and an auto-theft charge, while Sully Delgadillo is charged with hindering the apprehension of a fugitive and auto theft. The charges reflect allegations at this stage, and the case remains subject to the legal process; neither arrest itself nor a criminal charge establishes guilt.

A stolen Toyota RAV4 belonging to Alston became another important part of the investigation. Authorities used Flock camera technology to help trace the vehicle, while surveillance information reportedly connected Noriega to Alston’s property before the SUV was driven away. Investigators also reportedly found fingerprints inside the vehicle that were linked to Noriega, adding another piece to the developing case as detectives worked to connect the physical evidence with the reported movements of the stolen vehicle as detectives reviewed the evidence.

The search ended early Sunday, when deputies arrested the couple at the Georgia Welcome Center along Interstate 20. The arrests occurred at approximately 2 a.m., two days after Alston’s death, bringing an intensive search to a close while investigators continued working through evidence and the circumstances surrounding the killing. Authorities subsequently canceled the public alert seeking information about Noriega. Investigators then faced the task of preserving evidence and clarifying each person’s alleged role.

For residents in Augusta and nearby North Augusta, the case moved rapidly from a neighborhood death investigation to a homicide prosecution involving two people. The initial request for surveillance footage showed how investigators were reconstructing movements around the Harrisburg area, while the later vehicle trail and arrest provided a clearer path through the evidence. Officials have not publicly disclosed every detail, leaving parts of the sequence to be resolved as the case proceeds and additional evidence is reviewed.

Alston’s death has become a case marked by arrests, charges and unanswered questions surrounding a life cut short. With Noriega and Sully Delgadillo facing charges, the court process will determine what evidence is established. For her community, the lasting impact is the loss of a 56-year-old Augusta woman whose death brought grief, alarm and questions that remain unanswered today locally.
