Fairfax Police Chief David Rohrer posts farewell video Fairfax County Police Chief David M. Rohrer, arguably one of the least known-most powerful people in our region, stepped down Friday after eight years at the top. The next day, he started his new job as Deputy County Executive overseeing the same police department, as well as the fire department, emergency management and all other public safety stuff. Deputy Chief James A. Morris was named acting chief on Thursday, and will be a top contender for Rohrer's job. Rohrer, 56, released this farewell message on YouTube Friday, and finally, proudly embraces the fact that Fairfax County is "truly one of the safest communities in our country, bar none." He also pays a sincere tribute to the officers who died during his 32 years on the job.
