Officers Braxton Shaw, Michael Coblentz and Nicolas Martinez were charged in a 59-point complaint for incorrectly identifying people as gang members or employees. According to Jackie Lacey, a Los Angeles district attorney general, the officers falsified identities and evidence that were later included in a state gang database.
Earlier this month, the California Attorney General revoked access to data that the LAPD entered in the database. This information accounts for almost 25% of the approximately 78,000 records in the database, Attorney General Xavier Becerra previously said.
A Shaw lawyer said his client would prove innocent.
"Braxton has dedicated his personal life and law enforcement career to improving the quality of life for everyone," Greg Yacoubian said earlier in an emailed statement. "As a Los Angeles police officer, Braxton has always led, approved, and validated the LAPD leadership. Once the facts are known, I am confident that Braxton will be released from any criminal liability."
CNN asked Coblentz and Martinez for a comment.
Letters to more than 750 people
On Tuesday, the prosecutor confirmed to CNN that it is now sending letters to more than 750 defendants, in whose cases at least one of the three officers was listed as a potential witness. The defendants are asked to contact the prosecutor if they believe that the involvement of the officials has been disadvantageous or deserves further review.
The review includes all cases of crime – including murders – that the three officers have been involved in since the start of their careers, the Los Angeles Times reported for the first time.
One of the three officials was released in January and is on trial in an administrative court. The other two are "transferred home" and their powers as a peace officer have been suspended, LAPD said in a press release earlier.
Another 16 officers are under criminal investigation, according to the prosecutor.
"The case was brought up to a total of 19 officers," Greg Risling, public information prosecutor in the Los Angeles district, told CNN earlier this month. "The remaining cases are currently being examined."
