Janette MacAusland, the Wellesley woman accused of killing her two children amid a contentious divorce and custody battle, will appear in court Wednesday to face murder charges.

MacAusland, 49, is expected to be arraigned in Dedham District Court on two counts of first-degree murder in the deaths of 6-year-old Ella and 7-year-old Kai MacAusland, the Norfolk County District Attorney’s Office confirmed.

MacAusland was arrested in Vermont after authorities say she turned up at her aunt’s home in Bennington on April 24 “appearing highly distraught” and with a visible neck wound. She allegedly admitted to her aunt that she had killed her children and tried to take her own life, adding, “I wanted the [three] of us to go to God together but it didn’t work.”

MacAusland also told police she strangled her children and left them in her bed, The Boston Globe reported. Bennington officers requested a welfare check at the family’s home in Massachusetts, where Wellesley police ultimately found the two MacAusland children dead inside.

Norfolk County prosecutors have said little about what allegedly occurred inside the family’s home on Edgemoor Avenue, and a Dedham District Court judge has impounded the Massachusetts State Police report on the killings for six months.

Court records indicate Samuel MacAusland — Janette MacAusland’s husband — filed for divorce in October and sought custody of the couple’s children. Janette MacAusland also filed for custody, and the couple agreed last month to have a court-appointed guardian ad litem investigate the “legal custody and parenting plan issues” and offer recommendations to the court.

The MacAusland children were in kindergarten and second grade at Schofield Elementary School, Wellesley Superintendent David Lussier previously told the Associated Press.
