For the first time in over a decade, there will be a challenger in the race for Onondaga County District Attorney. And now, that challenger is getting an endorsement that's raising some eyebrows.

Former Syracuse Police Chief Frank Fowler is throwing his support behind Chuck Keller in the upcoming election.

Fowler retired as Syracuse Police chief back in November. 

Keller is looking to unseat longtime DA William Fitzpatrick, who took office back in 1991. He has run unopposed at least five times since.

Keller is no stranger to Fitzpatrick. He's an experienced defense attorney who has been seen across the courtroom many times.

Keller is running on the Democratic, Working Families, and Libertarian lines.
