Protesters demand justice for Natasha McKenna following deaths in Louisiana, Minnesota

Protestors gathered in Fairfax County Monday to demand justice for Natasha McKenna - a mentally ill inmate who died in police custody over a year ago.

McKenna, who had faced charges of assaulting a police officer, was involved in a February 2015 jailhouse struggle with several deputies while she was being transferred from a facility in Fairfax to a facility in Alexandria.

No charges were filed against the officers involved in McKenna's transfer, however, the case remains the subject of a federal civil rights investigation.

Renewed interest in McKenna's death has come about after recent officer-involved shootings in Louisiana and Minnesota - followed by a shooting in which a gunman killed five police officers at a Dallas protest march.
