He graduated from a high school in San Jose, where he had grown up, in 1989, and soon after, he joined the Marines.
Gunnery Sergeant Menusa was killed on the ninth anniversary of the day he began dating his wife Stacy. He was not a United States citizen, as he had failed to appear for his INS interview: He had been called to Hawaii on duty already.
Menusa had been stationed in many places around the world during his career with the Marines: He fought in the Gulf War, and he had been stationed in San Francisco, California, Cuba and Japan.
Menusa was survived by his wife, Stacy, 3 year old son Joshua, mother Virginia Kenny, step-father Michael Kenny and three brothers.
