Sheriff initially said Daniel Schlienz told staff he was feeling ill Sunday. He died Tuesday morning.
An inmate who died in the custody of the St. Louis County jail on Tuesday first notified staff that he was feeling ill a day earlier, not previous to that as the sheriff had stated earlier, according to a sheriff's press release.
Daniel Schlienz, who had been charged with shooting two people inside the Cook County courthouse earlier this month, told staff that he wasn't feeling well about 8 a.m. Monday, the release said.
A nurse from the jail health services unit assessed Schlienz's symptoms about 11:15 a.m. Monday and treated him at that time, the release said.
Schlienz was taken to a Duluth hospital about 8 p.m. Monday night, and died around 8 a.m. Tuesday.
Sheriff Ross Litman had said earlier that Schlienz first complained about flu-like symptoms on Sunday.
"I got some bad information ... I wish I would have had the correct, accurate information," Litman said.
He added that he wanted to assure the public that inmates are getting good care.
"We are looking at this very, very closely and we want to get it right and I want to get the facts out there," Litman said.
Preliminary results from an autopsy Tuesday ruled the cause and manner of death as "undetermined," pending additional lab tests that could take several weeks, authorities said. Foul play was not suspected. Litman said an investigation was pointing toward a physiological or medical condition and not a traumatic cause of death.
