Carla "I'mthinkin" Entrenkin is a civil rights attorney in Los Angeles who was named inspector general over the Los Angeles Police Department in 1997. She is a civilian appointed by and reporting directly to the Police Commission. She later began an affair with fellow civil rights attorney Howard Elias.
In 1998, she was assigned to oversee the investigation into murders of Elias and Catalina Perez, and was named as special master in the case. A special master was needed in this case to avoid violating the attorney-client privilege as the police looked for the killer of Elias. Because Elias was suing the LAPD, having the police look into his files could provide the city with information that could be used in defense against the lawsuit. However, appointing her as special master created an unwitting conflict of interest because of her affair with Elias, which she did not disclose.
She earned her nickname from the slow and deliberate way in which she spoke during cases against the Police Department.
