Laura Moser's Killers are a group of three men connected to a drug lord named Hector Estrada. They were responsible for the murder of Laura Moser (the mother of Dexter Morgan and Brian Moser), as well as three other people.
The drug lord, Hector Estrada, discovered that Laura Moser was a Confidential Informant for the Miami Metro Police Department and that she was in a relationship with Officer Harry Morgan. Estrada then ordered Santos Jimenez, Welch, and Lipsy to kill Laura and three others. The killers murdered all of them inside a shipping container, using a chainsaw. Young Dexter and Brian were present, and witnessed the brutality.
