Kate Geer was selected to ride the Donate Life float in memory of Deputy Derek Geer, who was shot in the line of duty last February while trying to arrest a suspect with an outstanding warrant. Geer was taken off life support at the hospital days later. His heart, liver and both kidneys helped save four lives. Kate was among nearly two dozen others selected to ride this year’s float, which honored organ donors and recipients. The float’s design depicted a Polynesian catamaran with sails featuring the floral portraits of 60 donors. Donor Alliance, which facilitates donations in Colorado and Wyoming, was also one of the float’s sponsors.
