Less than two weeks after authorities say he opened fire on a prosecutor and witness inside the Cook County courthouse, defendant Daniel Schlienz fell ill this week and died Tuesday morning in a Duluth hospital, officials said. Authorities are still investigating his death.
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.
"An investigation is pointing toward a physiological or medical condition and not a traumatic cause of death" St. Louis County Sheriff Ross Litman said Tuesday afternoon.
The 42-year-old Schlienz was being held in the St. Louis County jail on charges of attempted first-degree murder and other crimes after shooting two people in Grand Marais on Dec. 15 after a jury convicted him of a sex crime.
On Monday, jail staff called 911 at 7:49 p.m. and an ambulance took Schlienz to Essentia Health-St. Mary's Medical Center in Duluth, authorities said.
Schlienz had complained of flu-like symptoms starting on Christmas day, Litman said "but nothing out of the ordinary or to the extent to cause any alarm upon our staff." A nurse at the jail examined Schlienz on Monday morning and he was taken by ambulance that night.
"It wasn't until [Monday] that his condition worsened," Litman said. Symptoms included nausea, vomiting, fever and body aches, Litman said.
Schlienz was in a cell by himself and being checked on at least every half hour, Litman said.
