The dark cloud Damacio Diaz and Patrick Mara have cast on the Bakersfield Police Department now includes the Kern County District Attorney's office.

On Friday, District Attorney Lisa Green announced the department will be sending 64 letters to defense attorneys who had cases that involved Diaz or Mara serving as active participants in the gathering of evidence, interview process and/or writing reports.

The defense counsel can then decide to request a hearing regarding a potential new trial or plea agreement based on how much evidence remains with Diaz or Mara's participation removed.

Green said 87 cases were evaluated involving Mara and Diaz from 2010 to 2014, the time their criminal activity is believed to have taken place. 

Diaz was sentenced to five years in prison earlier this month. Mara will learn his fate on October 24th.

Bakersfield Police chief Greg Williamson said he will not comment until Mara has been sentenced.
