A dated photo of Farhan Towhid (2nd L); his brother, Tanvir Towhid (L); his father, Towhidul Islam (C); his mother, Iren Islam (R); and his twin sister, Farbin Towhid. | Bangladesh Association of North Texas Farhan Towhid, a chronically depressed 19-year-old Texan who formed a murder-suicide pact with his older brother and killed their parents, sister and grandmother over the weekend, was raised in a religious Muslim family but acted against his faith, according to Hasmat Mobin, president of the Bangladesh Association of North Texas. “He was a ... religious person. He used to go to mosque. He used to go up to different places. His father used to take him. In the ninth grade, his problems [with depression] started,” Mobin, who believes the strain of the COVID-19 pandemic on Farhan’s mental health could also have played a role, explained to The Christian Post on Tuesday.
