Mother-of-two, 39, dies from E. coli she contracted caring for her dying toddler four years ago

A 39-year-old mother has died four years after contracting a strain of E. coli that killed her young daughter.

Karen Odens' little girl Sophia contracted the bacteria on February 5, 2014, from a mystery source. Despite being rushed to the hospital near their home in Detroit Lakes, Minnesota, the four-year-old died days later.

But then, Karen fell ill with the same flu-like symptoms, and was forced to go through kidney dialysis for weeks.

After a month, she was discharged, but battled dangerously fluctuating blood pressure for years, in and out of hospital 30 times.

Eventually, she contracted kidney failure, and died on July 14
