BAKERSFIELD, Calif. — The law firm of Rodriguez & Associates announced they are requesting the Kern County District Attorney's Office open a criminal investigation into Supervisor David Couch, among others, for allegedly filing illegal documents questioning the residency of 4th District supervisor candidate Emilio Huerta.

In a release sent Thursday, the firm called for the investigation to include Couch, Bakersfield Attorney Brandon Martin, Delano Mayor Joe Aguirre and Fernando Flores.

Documents filed with the Kern County Superior Court in January show Aguirre filed a petition to have Huerta's name taken off the ballot. According to the documents, Aguirre alleged Huerta did not live in the district.

In January 23ABC asked Huerta about the allegations. Huerta acknowledged he had a residence on Oleander Street in Bakersfield but his main residence remained on Belmont Street in Delano.
