A son, an athlete, husband, soldier, father, grandfather and great-grandfather, Bill was never far from family and friends.
Whether on his horse, tractor, or 4- wheeler, family and friends were enjoying his stories or his words of advice.
Bill graduated from the University of Idaho in 1957 and was commissioned as a second lieutenant in the United States Army.
He was sent to Germany as a company commander of a guided missile site.
In 1965, Major Cossey was sent to Vietnam to be in charge of finding small groups of insurgents and directing air strikes.
Vietnam honored him with a Silver Star and the United States Army awarded him the Bronze Star.
After returning home, Bill returned to college and became a teacher and a coach.
He was a science and math teacher at Deer Park Junior High for over 25 years as well as coached boys and girls basketball and football.
His dream was to own a ranch, raise horses and cattle.
Hilltop Ranch became a reality in 1966 and he and Roberta raised their four children there.
Through farm life he gave all of the children a work ethic, a sense of family and community.
Two of the children still reside on the farm.
Bill is survived by his wife of 59 years Roberta and four children; Karen Capp and her children, Logan, Adam, and Laura; Robert, his wife Stacy, their children, Tyler and Danielle; Kevin, his wife Rita, their children, Sheldon and Brittney, her husband Robert Lee and daughter Makenna; Anne-Marie, her husband Mark Holmes, and their children, Ryan and Micah.
