Police find drugs, cups of 'red liquid' in home where Utah family mysteriously died

WARNING: Some details of this story are disturbing.

PROVO, Utah -- Police discovered medications and cups filled with a “red liquid” next to the bodies of five members of a Utah family.

In court documents obtained by KSTU/FOX 13 late Wednesday, police reveal details about the deaths while seeking access to computers and information about a “homicide” involving Benjamin and Kristi Strack and their children.

The Strack's 18-year-old son made the grisly discovery last month.

“Investigators at the scene determined the cause of death to be an accidental or intentional poisoning either by ingestion or environmental causes,” police wrote.

In another warrant affidavit, officers said they found the bodies of Benjamin and Kristi Strack and their children Benson, 14; Emery, 12; and Zion, 11; inside the master bedroom.

“Kristi and Benjamin were lying in the bed and the three children were lying around the bed, covered in bedding up to their necks,” police wrote in an affidavit. “Officers reported there was a red liquid substance coming from the mouth of Kristi Strack. All the occupants of the home were non-responsive. Next to each of the victims was a cup/drink with a liquid inside.”

Police wrote in a search warrant affidavit that they recovered boxes of cold and flu medication.

“Also in the same closed bag, were two empty boxes of allergy relief medication consistent with generic Benadryl. Approximately five empty blister packs were located for this medication. Among the items located were cups with a red liquid substance in Pepsi cups. Also located withing the residence were empty bottles of liquid Methadone. The Methadone was dispensed to from a drug treatment clinic. Some of the empty bottles had future dates on them,” the search warrant affidavit said.

An officer stated in another affidavit that it is probable the deaths were not accidental, writing: “…with the placement of the bodies, it would appear somebody had to position the bodies after they were deceased.”
