How can I find the owner of a 1966 High School ring I found? It has 3 initials and school name, but no state.?

My father died & I found it in some of his things. It is a man's ring and appears brand new. It has a dark blue stone.The school is; TURNER HIGH SCHOOL. The initials, written in script inside, are; ALS. There is some type of cat one one side. It could be a wildcat, cougar, lion, etc. On the other side are the numbers 66. The inside is also engraved with the trademark, GOLD LANCE, with a lance between the words. It also has, STUCKY & SPEED engraved below the lance.
