Beauregard("Beau", for short) is the son of Constance and Hugo Langdon and the brother of Tate, Adelaide, and one other unknown sibling. He is a character in the first season (dubbed by fans "Murder House") portrayed by Sam Kinsey. Unlike most other ghosts, Beau is a very kind and innocent soul.
Beauregard ("Beau" for short) was kept chained in the attic by his mother when his family lived in the Murder House. He was smothered with a pillow by Larry Harvey at Constance's request. However, Constance refuses to admit this, instead saying he died of natural causes. His spirit is currently trapped within the house's attic. Constance was going to be charged with child neglect, meaning Beau would be institutionalized by Child Protection Services, and she couldn't bear the thought of "them taking away" her family. It is still unclear if she neglected one or all of her children. It was, however, 1994, the year in which Tate committed the Westfield High massacre. Later on, Constance visits him and tells him they will be separated because of Joe Escandarian's plan to tear the whole house down.
He is afflicted with craniodiaphyseal dysplasia and seems to suffer a mental disability as well. He is very friendly in all of his encounters with other people, despite the horrific conditions his mother has kept him in.

Beauregard Langdon: "Nnnghhh!"
Beauregard Langdon: "Play!"
In "Home Invasion", Adelaide is seen playing with a ball in the basement, and the ball mysteriously returns to her. It was the same red ball Beau passed to Larry and later Violet to play with him in "Open House". After these three instances, it seems that Adelaide was just playing with her brother Beau, and that Beau can appear in both the attic and basement.
