A roommate injected heroin into a 20-year-old woman just hours before she was found dead in her apartment Tuesday morning near UW-Madison, court records allege.
Dane County Deputy Coroner Jeff Scholts said toxicology tests that would determine Sarah M. Stellner’s cause of death could take up to two months to complete. He would not speculate on whether heroin caused her death, except to say that she didn’t suffer any traumatic injury. Stellner was not a UW-Madison student.
