In the 800 block of West Chambers in Jacksonville on Saturday evening, the city was shaken by a fatal shooting that claimed the life of 31-year-old Marcquila Harris. Just after 5:40 p.m., police were called to the scene after reports of gunshots. When officers arrived, they found Harris with a life-threatening gunshot wound and rushed her to Jacksonville Memorial Hospital, where she later died.
A coordinated investigation began almost immediately. Detectives, working with Illinois State Police crime technicians, the Morgan County Sheriff’s Department, and the coroner’s office, spent the night piecing together what happened. By Sunday afternoon, they had identified and taken into custody 23-year-old Marissa Teubner of Jacksonville.



Teubner is now held in the Morgan County Jail. She faces charges of first-degree homicide and aggravated discharge of a firearm. Officials have said the case remains under investigation, with few details released about what led up to the shooting.
Friends and neighbors in the quiet West Chambers neighborhood spoke of disbelief and sorrow. Harris was remembered as someone with deep roots in the community, a woman whose loss has left family and friends struggling to make sense of the sudden tragedy.
Police continue to urge anyone with information to come forward. They believe that even small details could help clarify the circumstances that brought a life to an abrupt end on a Saturday evening.
As the community absorbs the news, local leaders are calling for unity and calm, while expressing condolences to Harris’s loved ones. In the days ahead, more may emerge about both the motive and the events that led to her death.
For many in Jacksonville, the shooting is a stark reminder of how quickly violence can upend lives — and how communities must lean on shared grief to move forward.
