No charges have been filed yet as the coroner’s office is conducting extensive toxicology testing on Bianca Haas, the 22-year-old missing woman whose body was found decomposing in a Waukegan apartment.

The Waukegan Police Department responded around 1 p.m. on July 28 to the 100 block of Drew Lane in Waukegan for a report of a deceased person.

Waukegan Deputy Police Chief Joe Florip said the call came in to the police department from a person that went into the apartment and found the body.

Officers and paramedics confirmed the subject was deceased.

Florip said the body was “decomposing.” The apartment was not vacant.

The Waukegan Police Department’s Criminal Investigations Division was called to the scene to investigate.

The Lake County Coroner’s Office transported the body to their office for an autopsy and identification.

The body was identified as Bianca Haas, 22, of Mount Prospect.

Lake County Chief Deputy Coroner Steve Newton told Lake and McHenry County Scanner on Thursday that Haas’s cause and manner of death have not been determined yet.

The coroner’s office is doing expanded toxicology testing on the woman, Newton said.

Because of the comprehensiveness of the testing, the results take longer than normal toxicology testing.

No obvious injuries were found on the woman’s body during the autopsy, Newton said.

Florip told Lake and McHenry County Scanner on Thursday that no charges have been filed yet in the case because it is still unknown if Haas’s death was a homicide or not.

Detectives are waiting for follow-up information from the Lake County Coroner’s Office and the Lake County State’s Attorney’s Office.

“It is an active and open investigation,” Florip said.

In June, the Waukegan Police Department issued an alert on social media asking for help in locating Haas.

Haas was last heard from in early February. She was known to frequent the Waukegan and Park City areas, police said at the time.

The Waukegan Police Department said Haas was officially reported missing in April in a different police jurisdiction.

Florip said in June that Haas was reported missing by one of her parents to police in Mount Prospect.

Her parent told police that Haas was last seen at the Drew Lane apartment in Waukegan.
