This house is where Dexter Morgan and Brian Moser lived with their mother (Laura Moser) before Laura Moser was murdered. It is here that Dexter lived before being taken in by the Morgans when he was three years old. It is a simple one story house with a patio. Even though it is no longer where Dexter lives, this house continues to be a haunting memory for Dexter as the series progresses.
Dexter first came to this house in search of his sister Debra Morgan who was kidnapped by Brian. When he arrived he had flashbacks to his childhood and remembered his brother and mother. Brian then took him to the garage to kill Debra Morgan in the style in which he is used to. Dexter, however, refused and had a brief struggle after which Brian escaped before the police arrived.
Debra later returned to this house in search of one of Harry's informants who he had an affair with only to discover it was the same house that she was taken to be killed. This later led to the discovery that Dexter and Brian were biological brothers.
