Three deputies, a local TV station reported earlier today.
The investigation into the situation is still ongoing. Although Sgt. Glans resigned, there were two other deputies on the scene during this incident, neither of which came forward until after the video surfaced. Zurlo says they are still being questioned and the matter is still under investigation.
