Det. Cyrus "Lupes" Lupo is a fictional character on the long-running NBC series Law & Order, played by Jeremy Sisto. He replaced Nina Cassady, who was written out of the show due to Milena Govich's departure from the cast.

Character development

Prior to his transfer to the 27th Detective Squad, Lupo spent 4 years as a member of the NYPD Intelligence Division investigating terrorist groups overseas in Iraq, Pakistan, and Morocco; while on this assignment, Lupo often worked alone, without backup and unarmed. He is cited as closing important cases in "very unfriendly parts of the world, without warrants, without a weapon, and without back-up". Before this, he was a patrolman in the 27th precinct. His shield number is 2632.

While Lupo was still a patrolman in the 27th Precinct, he witnessed a Christmas morning crime scene in which a father murdered his wife and two children. This bloody crime scene left him with PTSD and he began drinking to deal with the mental trauma. While he was abusing alcohol, he appeared in court to testify against the father who committed the crime, and the defense lawyer discovered he was under the influence while testifying on the stand. He continued drinking until he fell asleep while hung over on the job and his partner was shot dead because of it.

Lupo then partners with Ed Green in order to solve the assisted suicide death of his brother. In a later investigation, he takes advantage of an opportunity to learn the names of the practicing psychiatrist's patients by e-mailing himself the patient list on his BlackBerry. The evidence obtained is later ruled inadmissible. Lieutenant Anita Van Buren rebukes Lupo and Green for a "bad search".

When Green leaves, Lupo becomes the second detective to be promoted from Junior to Senior Partner. Both Green and current partner Kevin Bernard call him "Lupes".

In the season 20 episode "Just a Girl in the World", he gets romantically involved with a manipulative witness (played by Camille Chen), who later turns out to be a suspect; Lupo nearly ruins the case as a result.

In the season 18 episode "Illegal", Lupo tells Executive A.D.A. Michael Cutter that he's from Rego Park, Queens.

It is often mentioned on various occasions that he is currently in law school. This comes into play in his dealings with E.A.D.A. Michael Cutter and A.D.A Connie Rubirosa.

Personality

Though his religious affiliation, if any, is unknown, Lupo appears to have some knowledge of the Bible, as he correctly identifies a quotation as being derived from the book of Romans. He attended Catholic School as a child, and refers to the teaching nuns as gangsters.Prior to her marrying his brother, Lupo had been involved with his sister-in-law. It has also been revealed that he speaks both Spanish and Chinese, and is taking first year Law Courses at Brooklyn College, part of the City University of New York, which does not have a law school. The CUNY law school is located in Flushing, Queens. (There is a Brooklyn Law School located at 250 Joralemon Street Brooklyn, New York, 11201 USA, but it is not affiliated with the CUNY System). There is an inside joke in which Lupo thinks about "getting a dog". He later takes one home, named "Otto". He once said during the funeral of one of the victims that he hates funerals.
