Montgomery County attorney Robert Kerns, 66, has been charged again for rape and related offenses, this time by the state Attorney General’s Office, which was referred the case when misinterpreted lab reports forced the county District Attorney’s Office to drop similar charges related to the same offense.

Kerns has been accused of raping and sexually assaulting a female paralegal who worked at his law firm after a firm event in October 2013, the Attorney General’s Office said in announcing a criminal complaint was filed against Kerns on Friday.
