Delnor-Community Hospital was on lockdown Saturday afternoon after Tywon Salters, an inmate in the custody of the Kane County Jail, grabbed a correctional officer's weapon.
A female ER nurse who was taken hostage was not injured, police said, and was with family Saturday evening.
The incident started at about 12:30 p.m. in a small room near the hospital's emergency room. At about 4:15 p.m., Salters was killed when SWAT officers moved into that room after negotiators were unable to get him out, said Lt. Patrick Gengler, of the Kane County Sheriff's Office.
Salters, who was charged with possession of a stolen vehicle from the Elgin Police Department, was being treated at the hospital since May 8. Police didn't disclose what he was being treated for. He had been in police custody since April 11.
