A forensic pathologist on Wednesday revealed the cause of death for "cult mom" Lori Vallow's 7-year-old son, J.J. Vallow, according to local reports.
Vallow is charged with killing her two children, J.J. and 17-year-old Tylee Ryan, around September 2019, and her husband's first wife, Tammy Daybell, in October 2019.
The 7-year-old boy, who had autism, died of asphyxia by a plastic bag over his head, Ada County coroner Dr. Garth Warren testified, according to East Idaho News reporter Nate Eaton.
Warren "did not see any trauma to the internal organs or evidence of overt natural disease to any of the organs," he testified, as Eaton reported.
