Murder House- "Give me my treat. You don't want the trick!"

Larry is one of the Murder House's previous owners, having lived there with his wife, Lorraine, and their two young daughters in the early 1990s. He claims to have been arrested and sent to prison after he was accused of dousing the beds of his wife and children in gasoline and setting fire to them while they slept, and that he is out due to terminal brain cancer.

While at first Larry is only warning Ben about the house, it quickly becomes apparent that Larry has a greater, if not psychotic, interest in pursuing the Harmons. He regularly harasses Ben, usually threatening him, or asking for money, until the situation comes to a climax.

Shortly after, Ben digs into Larry's past and discovers that he was not actually put in jail for what happened to his family, but placed in a psychiatric ward. Larry then admits that he fell in love with Constance while his family lived in the house, even murdering her son Beau at her request. He told Lorraine that he was leaving her and was having Constance move back into the house. Larry says that after telling his wife about his plans, she locked herself in their daughters' room and set it on fire, which Larry alleges is the origin of his burns.

After the death of his family, Constance and her children moved back into the house with Larry. He tried to play the father role in Tate and Addie's lives as their father "left" several years prior, however, Tate disapproved of his relationship with Constance. Tate is aware that Larry is the one responsible for killing his brother, Beauregard and retaliated by dousing Larry with lighter fluid and setting him on fire the morning he committed the Westfield High Massacre, which is the real story behind his burns.
