Five members of ​Utah family died from "drug toxicity"

SALT LAKE CITY - Police say five members of a Utah family found dead last fall died from methadone and other drugs, and interviews with people who knew them revealed the parents worried about a "pending apocalypse."

Springville Police Chief J. Scott Finlayson said Tuesday authorities have concluded their investigation into the September deaths of Benjamin and Kristi Strack and three of their children, ages 11, 12 and 14.

He says authorities determined the cause of death was "drug toxicity," and the parents and the 14-year-old committed suicide.

The other two children's deaths were ruled homicides. However, Finlayson says there were no signs of a struggle.

The couple was found in a bed surrounded by their children.

Finlayson says interviews indicated the parents were concerned with evil in the world and wanted to escape from "impending doom."
