A Fairbanks woman is charged in the deaths of two of her young daughters, who died two years apart.

Stephany Lafountain, 23, is charged with first- and second-degree murder for the deaths of her daughters, who were 13 months and 4 months old when they died.

Fairbanks police say in November 2017, Lafountain called 911 and her husband's family to report that her 13-month-old daughter was not breathing. Her husband's family was able to get to her house on Fort Wainwright and begin CPR. Medics took the baby to Fairbanks Memorial Hospital, and then Providence in Anchorage, where she died a week later from a lack of oxygen to the brain.

Fort Wainwright police transferred the investigation to the Fairbanks Police Department since Lafountain and the baby were not military personnel. In the investigation, FPD found that two years earlier, in 2015, Lafountain, whose last name at that time was Bilecki, had a baby who died in similar circumstances.

In September of 2015, Bilecki called 911 saying her 4-month-old daughter was not breathing. The baby was taken from Bilecki's home on Third Ave. in Fairbanks to the Fairbanks Memorial Hospital, where she died just over an hour later. That baby's cause of death was officially undetermined, but police have since found that the symptoms were consistent with a suffocation death.

That discovery had police look further into the deaths of both girls. Police found that an hour before Lafountain reported her 13-month-old wasn't breathing, she'd searched for things including:

Police say autopsies on both girls showed they were both healthy, with no genetic abnormalities, diseases or injuries. The girls did not have the same father.

On August 29, Lafountain was indicted on one count of murder 1, and two counts of murder 2 for each baby. She was arrested Thursday afternoon.

Fairbanks police say Lafountain has no other children.
