Fontana police officers served a search warrant and seized several electronic devices which the department said would be analyzed for further evidence of child pornography. Investigators allege Goodwin transmitted the images using the email address of loweredforlife@yahoo.com.

Sheriff John McMahon said in a statement that Goodwin was no longer employed by the San Bernardino County Sheriff’s Department.

“I find it extremely disappointing when a member of our department acts in a manner that discredits the good work being done daily by our deputies,” McMahon said. “The fact that a sergeant has been arrested makes this particularly egregious because they administer supervision of line staff.”

Goodwin had been employed with the department since 2005. He was las assigned to the Gangs/Narcotics Division.

Goodwin was being held without bail and is due in court Monday.
