Soon after traveling back in time to July 20, 1969, Jay killed guidance officer Wayne Ellis at his own home so that Anthony could obtain his ID badge. Soon after that, still at Ellis' house, Jay calls for a plumber to come fix a pipe burst. Jay murders the plumber with a garrote wire when he arrives for the plumber's uniform. Flynn uses the uniform as a disguise to enter Lockman Aerospace and speak with his mother, Maria Thompkins.
Later, when Rufus Carlin and Katherine Johnson are removing the computer virus that Anthony uploaded onto NASA's equipment, Rufus had a gun pointed at Anthony. Jay was shot and killed by Rufus when Jay tried to make a move to shoot Rufus and protect Anthony.
