Jessica Hagan, Calgary Special-Needs Teen, Found Dead In Cranston Home

Calgary police are investigating the suspicious death of a teenager who relatives have identified as a 19-year-old with special needs.

The body of Jessica Hagan was found in her parents' home on Tuesday afternoon.

Her brother, Daniel Hagan, confirmed her death in a statement Wednesday, calling her "the most purely loving person'' he has ever known and saying her death is a "devastating" loss for the family.

Another injured woman, who Daniel Hagan has confirmed is his mother, Christine Hagan, was also there when officers arrived.

Duty Insp. Kelly Campbell confirmed Wednesday that a woman at the scene was taken to hospital but wouldn't give further details.

Neighbours tell CTV Calgary that Christine Hagan was in treatment for pancreatic cancer.

"We haven't determined that a crime has taken place," Campbell told a news conference. "The autopsy hasn't been completed so we're trying to get information, we're working very hard with the Medical Examiner's Office to determine the cause of death and the manner of death."
