Mario DeCapua was born April 12, 1922 in New Haven, Connecticut.  He died on Wednesday, June 7, 2023 after a short illness.  He will be inurned alongside his wife Rosel who was inurned in 2000 in the Columbarium, Arlington National Cemetery

Mr. DeCapua was a graduate of Miami University, Oxford, Ohio.  In 1942, Mario was drafted and served as infantry Rifleman with the 44th Division in France.  He was subsequently transferred to the Counter Intelligence Corps (CIC) which was in need of personnel who were fluent in the German language.  He served as a CIC Agent whose first assignment was to join a team of 4 other Language Qualified Agents to investigate the newly liberated Dachau Concentration Camp.  Their final report formed the basis of the 7th Army Publicans.   “SS Dachu”, Agents DeCapua and Crosby located and arrested Dr. Kurt Schilling, the camp doctor who infected inmates with the malaria germ, (reportedly 1000 inmates involved).  Schilling was later charged as a war criminal and hanged in 1946.  

After his discharge, Mario was hired to serve as Chief of Security for the US Displaced Persons Commission located in Frankfurt, Germany.  It was his responsibility to formulate the policy guidelines by which displaced persons had to satisfy before approval was granted for departure to the USA.  Mario continued in this capacity until 1952 at which time he was accepted by the Foreign Service, Department of State.  He served with the diplomatic service for 31 years in the Far East, Africa, and Europe.  In 1974, he was invited to attend the 9 month session of the 1974-75 program of the National War College, Fort McNair, Arlington, VA.  

Long after his retirement in 1981, he was hired by the Justice Department as an “Expert Witness” in cases involving war criminals newly identified as living in the USA.  Case files of these individuals were sent for his review and opinion as to their eligibility for remaining in the USA.  In most cases, he recommended deportation from the USA.  

Mario was preceded in death by his wife of 55 years, Rosel, as well as his parents and seven brothers.

Memories Timeline

Guestbook

  1. I had the wonderful pleasure of meeting Mario and Rosa when Alzheimers began to take Rosa’s memory. Lorraine and I began a journey of caring for Rosa until her passing. I have such fond memories of this home and the compassion and love that Mario gave Rosa.Lorraine remained in the home to care for Mario for years after. Mario was a sweet caring man that lived and saw much human destruction but always cared for his fellow person. I love you Mario and will never forget you!

  2. I loved talking to Mr. Mario Decapau! He always had a gleam in his eyes, so I called him “Young Man.” I will miss him greatly.

  3. May his family find comfort in knowing that Mr. Mario was love and greatly cared for. – Lacey, WA

  4. Mr. Mario will truly be missed. I have had the pleasure of meeting Mr. Mario through my sister Paulette, who has been his caretaker for many years. Before his death, Paulette put together a team of women to ensure Mr. Mario received round the clock care. I know he has touch the hearts of each and everyone of us who provided him with care. I didn’t think I would be able to work with someone of his capacity, but GOD had equipped me with the compassion and ability to care for Mr. Mario as if he was my own family! Paulette had him spoiled, so that didn’t make the job easy for the rest of us ladies. My friend is finally resting!

  5. I will always remember Uncle Mario so very fondly and with so much love. He was my grandfather’s brother and would often come to visit us on his trips from NC to CT. He was kindhearted, he had a fantastic sense of humor, brilliant, and he had a deep love for his family that shone in his wonderfully inviting smile and his sweet nature. He always brought so much joy and laughter and I will remember him always. He now joins his beloved brothers, Aunt Rosal and family. God Bless you Uncle Mario and thank you for so many wonderful memories ❤️

  6. I wasn’t notified of the passing of my uncle. I’m deeply saddened. He had such a kind soul and I will miss him very much. May he rest in peace. I will always keep him tucked in my heart.
