TUCSON, AZ (3TV/CBS 5) -- A Pima County Sheriff's corrections officer died on the job at the Superior Court building in Tucson Wednesday morning.
Ofc. Brian Krumm suffered a "fatal gunshot injury" in the secure area at the courthouse, the department said.
Pima County Sheriff Mark Napier says the Krumm's death was not the result of any contact with an inmate, and that he likely was alone when he died.
"There were several corrections officers nearby who were there within seconds of the incident, but the injuries to our corrections officer were fatal," said Napier.
The Pima County Superior Court building was put on lockdown after the death was discovered.
But the Sheriff’s Department said that there were no outstanding suspects or and that there was never any danger to the public.
"This is an incredibly sad day for our department," said Napier.
