A family of five in Springville, Utah is believed to have been poisoned last month, according to investigators.

Police reportedly suspected that the deaths of Benjamin Strack, his wife Kristi Strack, and three of their children ranging from ages 14 to 11 were "not accidental or natural in any way," when they were found in their home, according to newly-released search warrants filed in 4th District Court as apart of a homicide investigation.

The family was reportedly discovered dead on September 27 while at the time, Springville police reportedly told the media that there were no signs of carbon monoxide in the home, no trauma suffered and no obvious signs as to how the family died, according to the website KSL.com.

"The detectives on scene determined the cause to be an accidental or intentional poisoning either by ingestion or environmental causes," detective Raymond Flores wrote in an affidavit.

The parents' bodies were reportedly found in the bed, while the three children were found lying "around the bed," covered up to their necks with bedding, according to the affidavits.

"Furthermore, with the placement of the bodies, it would appear somebody had to position the bodies after they were deceased," wrote detective Jeffrey Ellsworth.

All five members of the family reportedly had cups of red liquid near their bodies. Kristi Strack reportedly had red liquid coming out of her mouth.

The family was reportedly found by the couple's older son and Kristi Strack's mother, according to Fox News. Strack's mother, Valerie Sudweeks, reportedly stated that she couldn't believe "she" would do this to the kids, but wouldn't elaborate on her statement, wrote police.

The results of a toxicology test are reportedly expected in late November, according to Springville police Lt. Dave Caron.

"Until I get those, I really don't have anything. I could come up with all sorts of theories, but it's not helpful," stated Caron.

Isaac Strack, Benjamin's older brother, reportedly asked the crowd at a recently held vigil to be patient as they waited for answers surrounding the deaths.

"We understand that there is healing that comes with those answers. We're confident those answers will come. We all have to be patient and wait until those answers come, and even when they do come, we won't know everything," stated Isaac Strack at the time.
