Trooper David Cibrian and Trooper Raymond Snisko of Illinois State Police were on duty when they received a call for a motorist assist around 4:15 a.m. Tuesday, Nov. 26, on Interstate 55.

When they arrived at the scene, the troopers learned that an organ transport vehicle had broken down. The vehicle was carrying a University of Chicago surgeon, a transplant coordinator, and a medical student on their way to the University of Chicago Medical Center with a donor heart.

Cibrian and Snisko responded immediately transporting the medical staff and heart to the hospital.

Thanks to the two troopers, doctors were able to successfully perform the surgery in a timely manner. According to WGN9, the transplant patient is recovering.

“Time is of the essence when it comes to transplant surgery,” stated Ashley Heher, director of Media Relations for UChicago Medicine. “There is about a four- to six-hour window of time for a heart to remain viable for surgery and the team had already been traveling for approximately three hours,” she said.
