John R. Lyons, 24, was fatally shot by police in Berwyn, Illinois, after a violent spree that left three people and two dogs dead. The rampage began Wednesday evening in Mahomet, a small town in central Illinois, and ended hours later in Berwyn, near Chicago. The first incident occurred around 9:30 p.m. when Mahomet police responded to a shooting on Riverside Drive. Officers found three victims with life-threatening injuries: Sara E. Mason, 26, was pronounced dead at the scene, while Janis L. Mason, 61, and Caleb M. Mason, 23, died after being taken to Carle Foundation Hospital. Lyons is believed to be responsible for the killings, though his motives are unclear.
Two hours later, Berwyn police received reports of an armed man near Home Avenue. Lyons fled on foot upon their arrival, breaking into a home on Wenonah Avenue and fatally shooting two dogs. The situation escalated as Lyons ignored police commands to surrender and opened fire on officers in a yard on Home Avenue. Police returned fire, killing Lyons. No officers were injured in the exchange.
The Illinois State Police Public Integrity Task Force is investigating Lyons' actions and the events leading to his death. Authorities are working to establish a clear timeline and uncover potential motives. The Berwyn Police Department has set up a confidential tip line at 708-749-6564, urging the public to provide information or video footage.
This tragedy has devastated two communities. Mahomet residents mourn the loss of the Mason family, known for their kindness and community involvement. In Berwyn, neighbors are shocked by the violent confrontation in their usually 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 seek answers to understand the events that unfolded, while law enforcement works to ensure justice and provide closure for the grieving families.
