A quiet evening in the small community of House Springs, Missouri, took a devastating turn on July 25, 2026, forever altering the lives of the Lashly family. Jessica Lashly, a 38-year-old single mother, was at home with her 17-year-old daughter, Jersey Greer. Known for her strong work ethic as an office manager for a tree service and her deep devotion to her children, Jessica was a beloved figure to her family and friends. That night, a dispute with a neighbor shattered the peace of their household. Her 73-year-old neighbor, Robert Winkelman, approached her home to complain about noise. This confrontation quickly escalated, leading to an act of unimaginable violence.
In the midst of their argument, Winkelman produced a handgun and shot Jessica in the head. Her daughter, Jersey, in a display of immense bravery, attempted to intervene and help her mother, but was also shot in the head by Winkelman. A third individual at the scene was chased by Winkelman but managed to escape without injury. Both Jessica and Jersey were rushed to the hospital in critical condition. Despite the efforts of medical staff and the prayers of their loved ones, both mother and daughter were taken off life support and passed away on July 27, 2026. In a final act of generosity, their family chose to donate their organs.
The Jefferson County Sheriff's Office quickly identified Robert Winkelman as the suspect. He was initially charged with two counts of first-degree assault and two counts of armed criminal action, but these charges were upgraded to two counts of first-degree murder following the deaths of Jessica and Jersey. However, before he could stand trial for his actions, Winkelman took his own life. When deputies confronted him at his home, he shot himself and later died at a hospital on August 2, 2026. The case concluded with the death of the sole suspect, leaving a community to mourn the tragic and senseless loss of a mother and daughter. The incident stands as a somber testament to how a neighborhood dispute can escalate to a fatal outcome, leaving behind a grieving family, including Jersey's twin sister who was not home at the time of the shooting.
