Cooley appeared on "Degrassi: The Next Generation" as a regular character in 2001, in the first season of the show and continued his role until 2007, while the show was in its sixth season. The writers decided to introduce the concept of a leading character death. At Liberty's birthday party there were two Lakehurst students urinating on his car. After J.T. confronted them, he stated, "You people slay me with your humor" before one of them stabbed him and he died. Eventually Lakehurst merges with Degrassi after Lakehurst burns down and almost everybody is unhappy that Lakehurst is there despite J.T.'s killer being in jail. He also had a baby with Liberty, but the baby was given up for adoption after J.T's attempted suicide with the drugs he had been selling in order to pay for the baby expenses.
