The inmate was also shot and underwent surgery Friday.
Both deputies were taken to the University of Kansas Health System, where one of the deputies succumbed to his injures, said Kansas City police Chief Terry Zeigler. Kelli Bailiff said at a news conference Saturday that 44-year-old sheriff's Deputy Theresa King had three children and 35-year-old Deputy Patrick Rohrer had two.
King, who served the Wyandotte County Sheriff's Office for 13 years, leaves behind three children. Robert King, who lives nearby, questioned why police didn't use nonlethal force.
"These were two bright and intelligent, wonderful personalities", Bailiff said of her fallen colleagues.
Officials told WDAF the suspect had been identified as Antoine Fielder, 22, an inmate who allegedly took hold of the deputy's firearm during a transfer from the courthouse back to the jail.
"The protocol has been in place for a long time and from what I observed and from what I believe the investigation will show is they followed proper procedure", she said of the deputies.More news: Cautious ECB slams Euro, boosts stocks - CMC Markets

'Our hearts break for our brothers and sisters at Wyandotte County Sheriff's Office as well as for the loved ones of the deputies shot today, one of whom has died.
The Kansas City Star reports that the shooting happened on Thursday afternoon in the north of the city.
The shooting happened Friday as an unidentified inmate was being moved.
Bailiff said the deputies were following protocol when the deadly altercation occurred.
"This is a courthouse building, there is video". They didn't give any details Saturday as to his condition.
Gov Jeff Colyer was briefed on the incident as he arrived to a congressional forum hosted by the Kansas City Chamber of Commerce.
The investigation is being handled by the Kansas City Police Department. Police Officer Zac Blair says authorities are reviewing surveillance video. Kansas City detective Brad Lancaster was shot during a pursuit in May 2016.
