Jessica Hagan killed by her mother Christine, now deceased: police

Knowing she had only days to weeks left to live, Christine Hagan gave her daughter Jessica, 19, who had Down syndrome, a lethal dose of drugs in September.

On Thursday, Calgary police announced Jessica's death was a homicide but said no charges would be laid because her mother had recently died of cancer.

"We're just trying to get over the loss of two integral family members and we're strictly in the grieving process," Brian vanVliet, Christine's brother, told CBC News.

Christine, who was in her 50s,was diagnosed with stage 4pancreatic cancer in May and though she prayed for a miracle, she knew in her heart she didn't have long to live, according to her brother.

"She was weak and very, very ill and it was just a matter of days before her passing," vanVliet said. "Christine was always a family first person, very caring, very boisterous, giving, loving."

VanVliet said he believes that in her final days, his sister was very upset about what she had done to herdaughter.
