Do you know who murdered Marie Riley? Native American/Indigenous woman Marie Riley, age 60, was found dead just after noon on October 31, 2020, inside a Fairview apartment on the 500 block of East 15th Avenue in Anchorage, Alaska. Police were called at 12:01 p.m., and responding officers discovered two people deceased inside the residence: 60-year-old Marie Riley and 63-year-old George Tretikoff. Crime scene technicians remained for hours to process the home while detectives opened a homicide investigation.
In the weeks that followed, detectives pieced together evidence that led them to a suspect. According to police and court filings summarized in local reporting, bloody handprints at the scene were a key clue that pointed investigators toward 26-year-old Christopher Ligons. He was arrested roughly two months after the killings, in late December 2020, on suspicion of first- and second-degree murder.
On January 29, 2021, an Anchorage grand jury indicted Christopher Ligons for the murders of Marie Riley and George Tretikoff and for tampering with physical evidence. The indictment formally charged him with two counts of first-degree murder, two counts of second-degree murder, and one count of evidence tampering for the October 31, 2020 homicides inside the Fairview apartment.
Authorities' public updates from that period did not announce any additional suspects or arrests beyond Ligons. The case narrative in official and local sources centers on the single identified suspect, the forensic evidence recovered inside the apartment, and the charges brought by the grand jury in early 2021.
