Autopsies: 1 ISU student suffered blood clot, another cold exposure in weekend deaths

Updated: March 3, 2014 1:34PM

Autopsy results released Monday determined a blood clot and cold exposure were behind the unrelated deaths of two people with ties to Illinois State University and the Chicago area who were found dead near the Downstate campus.

Police in Normal found Katie Borenstein, 20, a former ISU student who grew up in Buffalo Grove, unresponsive in her apartment about a block south of the ISU campus, authorities said.

Preliminary autopsy results show she died of a blood clot of the pulmonary artery, McLean County Coroner Beth Kimmerling said. Her death is not considered suspicious, and the final cause of her death will be determined following forensic toxicology and histology tests.

Borenstein majored in sociology and psychology at ISU, but was not enrolled there at the time of her death.

A second, unrelated death was reported about 7:30 a.m. Sunday, when police and fire officials found 19-year-old Yusuf “Yoshi” Ziada dead in a field about two miles east of campus in Bloomington, the coroner’s office said.

Preliminary autopsy results show he died of symptoms of cold exposure, and had no external injuries, but the final cause of death will be determined pending toxicology tests.

Officials said he was not dressed for the wintry conditions. The temperature in the area when his body was found was about 23 degrees.

Ziada was a sophomore business major at ISU, and a former member of the university’s chapter of the Delta Chi fraternity. Police believe he died after he wandered away from the Chateau Hotel in Bloomington, then collapsed, the coroner’s office said.

Ziada graduated from Oak Lawn Community High School in 2012, Principal-Supt. Michael Riordan said Monday.

“He was a good student and a fine young man. He was involved in our student council and served as a class officer during his four years [here]. Our thoughts and prayers are with his family,” Riordan said.

Ziada has two younger siblings who attend the school, he said.

Police from Bloomington and Normal continue to investigate both deaths.
