Sergeant Martiza Cruz was an NYPD police officer who worked at the 55th Precinct. She was portrayed by Tia Texada who starred from season 4 to the end of the series.
Cruz was an Anti-Crime Sergeant with the fictional 55th Precinct of the NYPD. She was often a renegade officer who does whatever it takes to get the job done. This is seen throughout her part in the series. This is proven during her commitment to duty which led her to being raped by a man while undercover.
Her family history is unknown: her only relative was her sister, Leticia (aka "Lettie"), who died of a drug overdose during a raid. At one point during her career; Cruz has a relationship with Bosco, but however this ends when Faith Yokas and Cruz shoot each other in self-defense in a hotel room during an illegal search. The shooting resulted in Faith being hospitalized and Cruz sent back to Patrol from Anti-Crime.
Cruz came under the microscope of IAB several times; one of which ended up with her in prison for the murder of a suspect. However Faith, the real killer, admitted to shooting a crime lord responsible for the murder of several 55th Precinct Officers (after gaining immunity from any punishment).
In the series finale, Cruz takes out a large street gang; during which she was killed after strapping two grenades to her body. Cruz was awarded the NYPD Medal of Honor. Her tombstone was also shown in the last episode showing her birth and death date, which also gives the date of the attack against the 55th Precinct (the Camelot) on May 5, 2005.
