Officer McMaster was the half-brother of Donald and Terry McMaster, sons of Raymond H McMaster's second marriage. He was called Junny for Junior within the family. He was 18 years older than me and that plus difficulties within the family kept us from ever knowing him well. I remember our father was devastated by his death. Junny's only child was a girl named Monica who went into law enforcement in Florida because of the example of her father. She tragically died on the operating table stemming from back injuries suffered as part of her job.
