Jack McKay, Chief Financial Officer of the American Psychological Association, testified as a defense witness about playing with Simpson in a corporate golf tournament at the Landsdown Conference Center in Sterling, Virginia, on June 8, 1994 — just days before the murders. Called by Johnnie Cochran, his testimony went through multiple rounds of redirect and recross with Marcia Clark, suggesting the details of Simpson's demeanor and physical condition that week became a point of contention between the two sides.
