Otto Martin William Neilson, III "Bill"

December 24, 1935 — April 29, 2021

Otto Martin William Neilson III “Bill,” aged 85, of Sunderland, MD. died Thursday, April 29, 2021, at the Maryland Masonic Home, Cockeysville, Maryland, surrounded by his wife and 5 of his 11 children. Bill was born and raised in Washington D.C. He was a proud Army veteran and Metropolitan Police Officer, retiring from the Special Operations Division. Bill was also a member of Demolay and was elevated to Master Mason in 1958 at East Gate Lodge #34. He served as Worshipful Master there from 1966 – 1967. After his retirement from MPD, Bill had several jobs including self- employment. He was head of security at Zayre’s in New Carrollton, MD. and Hutzler’s Department Store in Baltimore. Bill started his own private investigations firm, O.M. Neilson, and Associates. In the 1980’s Bill was employed by the Department of Transportation auditing interstate trucking companies for DOT compliance. That experience led him to start his own DOT compliance company auditing records and being a liaison for the trucking industry with Department of Transportation. Besides his passion for truth and justice, Bill loved ham radios, trains, and airplanes. But none surpassed the love Bill had for his family. Bill is survived by his wife, Jenny Cash, his children, Samuel Oliver (Kaye) of Hughesville, MD; Deborah McGuigan (CW), of Littlestown, PA; O.M.W.
