Marston, 31, of Concord, N.H., was assigned to an East-coast SEAL time and served in the Navy for six years. He completed SEAL training in 2009.
An investigation into the accident is underway.
Marston’s family says Blake was “the kind of guy you’d want your children to be around.” He was an accomplished athlete in high school and completed a post graduate year playing football and baseball.
He graduated from Stonehill College in 2007 with a degree in Criminal Justice. He enjoyed working out with his girlfriend and was an avid Crossfit athlete.
“Blake died doing what he loved most being a SEAL,” his family said in a statement. “His beautiful smile, loyalty, steadfast motivation and determination will forever be missed.”
He is survived by his loving girlfriend Christine Clarke, Mother and Father Bill and Nancy Marston, 3 siblings Chris, Jeffrey and Emily Marston, two nieces Kaley and Taylor Marston, Aunt Barbara and Uncle Erik Mostue and Aunt Debbie and Uncle Doug Irving along with a huge circle of loving family and friends.
