When deputies pulled up to the house on Wuensch Road on Tuesday afternoon, August 25, 2026, nobody expected a crime scene. A routine welfare check ended in total disbelief for the small town of Greenfield. Inside the home, officers found 48-year-old Sara Venzke and her husband, David Venzke, both dead from gunshot wounds.
The sudden loss sent shockwaves through the nearby St. Joseph’s Ridge area. For years, Sara was a familiar face to hundreds of patients across the region. She dedicated her life to taking care of sick people, working long hours and building a name for herself in the local medical field.
Her journey in medicine started on the hospital floor as a registered nurse. Coworkers knew her as someone who stayed calm under pressure and listened to patients when they were scared. She put in the hard work daily, earning the trust of doctors and families alike.
In 2015, life threw a heavy curveball at Sara when doctors diagnosed her with cancer. She faced the brutal treatments head-on and managed to beat the disease completely. Surviving that ordeal did not slow her down; it actually pushed her to go even further in her career.
After beating cancer, Sara went back to school to earn her doctorate degree. She pushed through years of tough studying until she officially became a nurse practitioner. It was a massive achievement that showed everyone around her just how determined she really was.
At home, Sara and David were celebrating two decades of marriage. The couple had been together for 20 years, building a steady life on their piece of land in La Crosse County. Friends and neighbors saw them as a solid, quiet pair who kept to themselves.
That quiet life came to a sudden halt when La Crosse County Sheriff’s deputies stepped through their front door on August 25. Investigators have kept details extremely tight, leaving loved ones with zero answers about what happened inside the house that afternoon.
With no information on a suspect or a motive, those who worked with Sara are left remembering a woman who beat illness only to die far too soon. Her decades of service in local healthcare stand as her lasting mark on the community she served.
