Patrick Bateman, M.D.

Patrick Bateman M.D., is one of Dexter Morgan's aliases.

The name is a reference to the main character of American Psycho. Bateman is a fictional wealthy, materialistic Wall Street investment banker who leads a double life as a serial killer.

Summary
Dexter had set up a fake account in the name of Patrick Bateman, M.D. in order to buy M99, a powerful animal tranquilizer. The substance, strictly controlled, could only be purchased with a DEA license.

When M99 was discovered in Valerie Castillo's body (one of Dexter's victims), Vince Masuka requested a list of people who were able to buy M99. Dexter, worried that his alias would lead back to him, hacked into Masuka's email and deleted the name from the list. Debra almost caught him doing this.
