Grant and his wife Ursula were owners of a billion dollar valued firm Hapstall Farmaceuticals. They didn't have any biological children, only two adoptive - Caleb and Catherine. ("It's Time to Move On")
Grant and Ursula were found gagged and shot to death at their mansion by their adoptive son Caleb Hapstall. It was initially believed by the police that both, Catherine and Caleb had killed their adoptive parents in order to get their inheritance. Grant's sister, Helena Hapstall heard the murder from across the road, claiming that the murders were so violent, it woke her up from her sleep. Helena was later silenced by Caleb via her death in order to prevent her from testifying any further in the Hapstall Case. Catherine ended up going to jail for shooting Annalise, however, after the news about Philip was dug up, Philip claimed that Catherine was with him on the night that Grant and his wife were killed, revealing to the world that Caleb was the true culprit. While the news came out, Caleb took his own life as a result. ("It's Time to Move On", "Hi, I'm Philip", "Anna Mae")
