Funeral being held today for woman, two kids who died in murder-suicide

WINDSOR, Ont. - A joint funeral will be held today in Windsor, Ont., for two young children and their mother who died in a double murder-suicide outside Ottawa.

Police believe 40-year-old Alison Easton killed 10-year-old Alex Corchis and six-year-old Katie Corchis before taking her own life last Monday in Stittsville, Ont.

They called it a "horrific" double murder and suicide.

No details about the cause of death have been released.

Police say Easton was involved in the local neighbourhood watch program, and a neighbour described the stay-at home mom as "very quiet."

The funeral is being held at All Saints Anglican Church at 11 a.m.
