An Oswego woman, Alexia Telles, age 28, has been given a 30-year prison sentence for the first-degree murder of her girlfriend, Annissa Ellen-Williams, in a disturbing case that culminated last week as she pleaded guilty; Kendall County State’s Attorney Eric Weis announced the sentencing led by Judge Jody Gleason in a plea agreement, according to FOX 32 Chicago and echoed by ABC7 Chicago.

Back in February 2023, the tragic sequence started when Telles arrived at a residence in Oswego with Ellen-Williams who was suffering from a severe head injury, later resulting in her death despite attempts by medical professionals to save her, investigators initially scrutinized the evidence that pointed to a grim scenario where an argument escalated to violence while Ellen-Williams was behind the wheel this led to an investigation where forensic and digital analyses combined with Telles' admissions to law enforcement revealed the reality that the murder was intentional and followed Telles's attempt to disguise it as a suicide.

Prosecution of such cases is notoriously complex, with Weis underscoring the inherent challenge since "only two people know exactly what occurred that fateful night"; nevertheless, he commended the exhaustive investigative efforts by Oswego police, Illinois State Police, and the Coroner's Office that led to Telles being held accountable for her "heartless act" as he detailed in a statement obtained by FOX 32 Chicago, the conviction spares the victim’s family the anguish of a trial and represents a bitter form of justice that too often seems elusive.

Telles, already detained since her arrest, will serve the entirety of her 30-year term at the Illinois Department of Corrections and must endure an additional three years of mandatory supervised release post-confinement.
