A 20-year-old Buffalo Grove High School graduate found unresponsive Saturday in her apartment near Illinois State University died from a blood clot in her pulmonary artery, according to an autopsy Monday.
Katie Borenstein was pronounced dead about 6:15 p.m. Saturday at her home a mile from the university's Normal campus, McLean County Coroner officials said. The final cause of death will be released after the results of toxicology and histology tests that could take two to six weeks.
Borenstein was not currently registered at Illinois State, but she was a sociology student in the fall semester, university spokesman Eric Jome said.
Her father is Assistant Will County State's Attorney David Borenstein. Her mother, Nancy Borenstein, is a Stevenson High School study hall supervisor.
"We were shocked and saddened to hear about the death of Nancy's daughter," Stevenson spokesman Jim Conrey said in an email. "Our thoughts and prayers are with Nancy and her family at this difficult time."
In a separate case, the body of a current ISU student from the South suburbs was found Sunday morning in a Bloomington field about two miles from campus. Yusuf "Yoshi" Ahmad, 19, who graduated from Oak Lawn Community High School, was pronounced dead about 8:25 a.m., authorities said.
Preliminary results from an autopsy Monday showed he had symptoms of cold exposure, the coroner's office said in a news release. Authorities said it appears Ahmad wandered away from The Chateau Hotel in Bloomington and then collapsed. He was "not dressed appropriately" for the weather, the coroner's office said in a news release. An official cause of death is pending toxicology results.
Ahmad served as a class officer in Oak Lawn's student council. Counselors will be available to students at the school, where Ahmad's two younger siblings attend, Oak Lawn Community High School District 229 officials said.
"He was a good student and a fine young man," Superintendent Michael Riordan said in an email.
