Gil Zamora retired as the forensic artist at the San Jose Police Department after 27 years. During his time there, he interviewed well over 3,000 eyewitnesses to crimes ranging from indecent exposure to murder. He was certified in the FBI Composite Art technique in 1993 and apprenticed with renowned police artist, Tom Macris, from 1992 to 1995. He developed his own interview methodology, Compositure (1998), based on the cognitive interview technique (Fisher & Geiselman, 1992) and focused on the elimination of post-event information to stimulate eyewitness memory. His interview technique led him to help solve several hundred investigations in the Bay Area and testify as an expert forensic artist in various criminal court cases.

In 2022 Gil embarked on writing a textbook about his mindful interview technique that sought to offer some guidance to investigators, practitioners, and criminal justice students on the art of interviewing eyewitnesses. In 2023 Cognitive Evidence Consultants was created to embrace his new focus on assisting law enforcement and private agencies to gather more reliable cognitive evidence.

The Efficacy of Eyewitness Interview Assessment was born out of evaluating the Mindful Interview Method. Today it can be used as an objective alternative to assist agencies in revealing how their personnel are gathering cognitive evidence.
