Five officers were involved in the shooting, Chief Eric Hawkins said Monday during a media briefing. The sergeant is resting at the hospital and should be released within several days.
Chief Hawkins declined to say the shooting was a "suicide by cop." He did say Collins was "struggling with some very serious internal issues." Collins apparently walked into the lobby with a "blank stare" and opened fire at the station's ballistic glass.
"That's what was so unusual," Chief Hawkins said. "There were no words whatsoever. The suspect appeared to be staring into the distance."
