(CNN) — There were no signs of trauma, no clues of any violence or foul play.

So investigators are trying to determine how five family members died in a Utah home over the weekend.

Officials identified the deceased relatives as father Benjamin Strack, 37; mother Kristi Strack, 36; son Benson Strack,14; daughter Emery Strack, 12; and son Zion Strack, 11.

Another son of the couple found the bodies on Saturday night, the Springville Department of Public Safety said.

Preliminary autopsy results have ruled out any sort of violent assault.

“The Medical Examiner has indicated that the next step is to continue the investigation through analysis of blood samples to determine what may have caused the deaths,” the Springville DPS said in a statement.

All five bodies were found in one bedroom of a duplex, CNN affiliate KUTV reported.

Firefighters entered the home in protective gear in case of carbon monoxide poisoning, the affiliate said, but they found no traces of the deadly gas.
