A tragic incident unfolded in Brooklyn Park, Minnesota, on April 25, resulting in the loss of two prominent individuals, North Dakota State Representative Liz Conmy and retired Mayo Clinic surgeon Dr. Joseph Cass. Newly released findings from the National Transportation Safety Board (NTSB) shed light on the circumstances of the small plane crash that claimed their lives.

The crash occurred at Southbrook Park just after midday, with police reporting that the aircraft went down shortly after takeoff from Crystal Airport (MIC) in Minneapolis. Emergency responders were faced with a significant scene, as a large plume of black smoke billowed from behind the treeline where the plane had impacted.
According to the latest NTSB report, the pilot issued an “abort” command shortly after departure, signalling distress. Air traffic control had cleared Dr. Cass to land on any available runway; however, the aircraft did not reach safety, descending almost vertically before crashing. Surveillance footage captured the moments leading up to the incident, showing the plane turning left before disappearing behind the trees.

Witness reports have indicated that the aircraft’s landing gear remained extended as it was about 150 feet in the air, an observation that is corroborated by the NTSB’s examination of video footage taken during the flight. This detail is critical as the presence of the landing gear at such a height is unusual and may indicate issues that contributed to the crash.
The plane impacted an area of Southbrook Park, located roughly 900 feet northwest of the runway’s departure end. Local authorities were quick to respond, but the severity of the situation left no survivors. The loss of Conmy, who was known for her dedication to public service, has resonated deeply within her community and beyond.

Representative Conmy was a member of the North Dakota Democratic-NPL and had a reputation for championing causes related to public education, environmental issues, and government transparency. In the wake of her tragic death, her party expressed profound sorrow, stating, “We are completely heartbroken and gutted by the loss of Representative Liz Conmy. This is a profound loss for our state.”
Those who knew Conmy have recounted her positive spirit and warmth. Representative Zac Ista described her as “a warm spirit” with an infectious joy, while former student Jarrod Schoenecker recalled her as “a bright smile in the room,” someone who brought an uplifting energy to all interactions. Conmy was not only a dedicated lawmaker but also a mother of four, which adds to the heartache surrounding her untimely demise.
Dr. Joseph Cass, the pilot of the ill-fated flight, was also widely respected in his field. His expertise as a surgeon and his contributions to the medical community were significant, further amplifying the weight of this tragedy.
As investigations continue, the specific cause of the crash remains undetermined. The NTSB has retained the aircraft for further analysis, which they hope will clarify the events leading to this devastating incident. This crash marks the second fatal aviation accident in Brooklyn Park in recent years, raising concerns regarding flight safety in the area.
The loss felt by the family, friends, and constituents of both individuals has been immense. Community vigils and tributes reflect the collective grief, as people recall the positive impact Conmy and Cass had on those around them. As the investigation unfolds, many are left to not only mourn their loss but also seek answers that may bring some closure to this tragic event.
