In a lengthy letter posted on one of the brothers’ social media pages, it described how they arrived at their decision to take their family’s lives and then their own.

54-year-old Towhidul Islam and his wife 56-year-old Iren Islam were among those found along with 77-year-old grandmother Altafun Nessa; 21-year-old Tanvir Towhid; and 19-year-old twins Farbin Towhid and her brother Farhan Towhid.

The time of the murders is still unclear but evidence suggests it may have occurred this past Saturday. The investigation is ongoing.
