A 24-year-old man, John R. Lyons, was fatally shot by police in Berwyn, Illinois, following a violent series of events that claimed the lives of three people and two dogs. Authorities revealed that the rampage began Wednesday evening in Mahomet, a small town in central Illinois, and concluded hours later in Berwyn, near Chicago.
The first incident occurred shortly after 9:30 p.m. on Wednesday when police in Mahomet responded to a shooting at a home on Riverside Drive. Officers discovered three victims with life-threatening injuries. Tragically, Sara E. Mason, 26, was pronounced dead at the scene, while Janis L. Mason, 61, and Caleb M. Mason, 23, succumbed to their injuries after being transported to Carle Foundation Hospital. Investigators believe Lyons was responsible for the killings, though his motives remain unclear.
Two hours later, Berwyn police received reports of an armed man near Home Avenue. Upon arrival, Lyons fled the scene on foot, breaking into a home on Wenonah Avenue, where he fatally shot two dogs. The situation escalated further as Lyons ignored police commands to surrender. Moving to a yard on Home Avenue, Lyons reportedly opened fire on officers, prompting them to return fire. Lyons was killed in the exchange, while no officers were injured.
The Illinois State Police Public Integrity Task Force is conducting an investigation into Lyons’ actions and the events that led to his death. Authorities are working to establish a clear timeline of the rampage and uncover potential motives. The Berwyn Police Department has set up a confidential tip line at 708-749-6564, urging the public to come forward with information or video footage.
This tragedy has left two communities devastated. Residents of Mahomet mourn the loss of the Mason family, remembered for their kindness and community involvement. In Berwyn, neighbors are grappling with the shock of the violent confrontation in their typically quiet neighborhood.
As investigations continue, local authorities and community leaders are offering support to those affected by this senseless violence. Both Mahomet and Berwyn residents are left seeking answers to understand the events that unfolded, while law enforcement works to ensure justice and provide closure for the grieving families.
