Benjamin "Ben" Rigsby is the son of Wayne Rigsby and Sarah Harrigan. He has appeared twice throughout the series, in seasons 5 and 6, although having been born in season 4.
Halfway through season 4, Harrigan announces she is pregnant to Rigsby. Although he wasn't truly in love with her, he wanted his child to have two parents. Therefore,he proposed to her, but he was ultimately rejected. In Something's Rotten in Redmund, Harrigan gives birth off-screen to baby Rigsby, whom they name Benjamin.
After the events of The Crimson Hat, in which Rigsby faked his death in order to trap Red John, which ultimately didn't work, she left him. Ben's first appearance is in Blood Feud, when his grandfather is murdered.
He then reappears in Wedding in Red. He is seen in the beginning of the episode in Rigsby's place. After the wedding of his father and Van Pelt, he has a new stepmom.
