Former trainer and jockey agent Elza McKay, 63, died Monday in Columbus, Neb. McKay suffered a stroke in the early part of this decade that left him in a wheelchair. He died at a care facility after recently being transferred from the hospital in Grand Island. McKay worked as an assistant trainer in the late 1960s before serving in Vietnam. Following his return, he worked for Jack Van Berg, then took out a trainer's license in the late 1970s and trained several successful runners at Park Jefferson in South Dakota. In the mid-1980s he turned to being a jockey agent, and in the last few years owned horses along with his sons Andy and Chad. Services are set for 9:30 a.m. Saturday at St. Anthony's Cathedral in Columbus.
