Manuel was raised on the Westside and attended “the big Kennedy Green”, Kennedy High School, where he played football, basketball, and baseball, graduating in 1968. He voluntarily enlisted after graduation in the U.S. Air Force and served honorably in the Vietnam War.
After returning home, Manuel completed his associate degree in Fire Science at San Antonio College and had a distinguished 30+ year career as a firefighter at both Kelly and Lackland Air Force Base, where he was respected for his leadership, courage, and steadfast service. Throughout these years, he formed deep-rooted friendships that became like extended family to him—bonds that lasted a lifetime.
In 1974, Manuel married the love of his life, Maria. Across their 51 years of marriage, their family grew to include 7 children and 10 cherished grandchildren. Family brought Manuel his greatest joy. He was quick-witted, loved to laugh, and cherished music of all genres and generations. He enjoyed gatherings with family, movies-particularly old westerns, cheering for the Spurs, watching football and baseball games—rooting for Texas teams.
Manuel is preceded in death by his parents, Manuel C. Casares, Sr. (2009) and Concepcion L. Herrera (1993); his brother Juan (1975); and his brothers Roberto and Juan, who passed in infancy.
