William J. Costigan III

August 27, 1963 ~ March 23, 2021 (age 57)



William J. Costigan III (57 Yrs.) died unexpectedly in a tragic fuel truck accident as a result of medical complications on Tuesday, March 23rd, 2021. 

“Billy” was born August 27th, 1963 in Bethesda, MD. He attended Sherwood High School where he was a star athlete in football and track & field. A few years after graduating in 1982, Billy created “Costigan’s Towing” in 1987 and became a staple of the community who was loved by many due to his good-natured soul. He moved on from the towing industry to partner up with his wife & best friend of 26 years, Tanya, in starting a fuel company, Metro Petroleum. 

Billy is survived by his wife, Tanya Costigan, children, Colin (C. J.), Nicholas, Danielle, and Joey Delmar, his father, William J. Costigan Jr., siblings, Chris, Tommy (Viquen), Gabby (Ed Schillo), and Colleen (Pfeister). 

In addition, Billy is now reunited with family members that he deeply missed every day, his mother, Helen Costigan, sister, Mary Beth, and children, Nicole, and Kristin Delmar. 

Billy was a fun-loving family man who touched the hearts of many. He loved attending all his children’s sporting events between Damascus High School, Good Counsel High School, and Salisbury University. He loved his cigars. He loved all dogs, and all dogs loved him. His larger-than-life self - strong, but sweet - won everyone over that he ever came into contact with. Billy was truly the guy that loved and cared about all family, friends, and man’s best friend - his dogs! He always loved as hard as he fought. 

Billy, we love you to infinity and beyond
