Springville • Police have identified the family of five who were found dead in their home Saturday night.

A Springville Police news release identified them Sunday as Benjamin Strack, 37, his wife, Kristi Strack, 36, two of their sons — Benson Strack, 14, and Zion Strack, 11 — and their daughter Emery Strack, 12. Preliminary autopsies ruled out any sort of violent assault, according to the release.

Another son of Benjamin and Kristi Strack found his family members dead inside their home near 900 South and 1000 East about 8 p.m. Saturday.

"At this point, the cause of death has not been determined, and won't be until the results of laboratory testing is completed," according to the release. The state medical examiner's office has not given police a time frame for when they can expect the lab work results.

The lack of what police said was an obvious cause of death and the absence Sunday morning of investigators at the home appeared to bolster the possibility, raised earlier by authorities, that carbon monoxide may be responsible for the deaths.

"This time of year, it's obviously something we're concerned with," Springville police Lt. David Caron said Saturday.

The Stracks were found in a duplex. Residents in the other half of the duplex were unharmed.

A relative spoke to the family on Saturday morning, Caron said.

Police and firefighters on Saturday removed live pets from the home.

Caron said firefighters tested the air and did not find any carbon monoxide, but the gas could have ventilated before the test.
