Cause of Iowa man’s suspicious death ruled undetermined

SERGEANT BLUFF (AP) — Iowa authorities have revised the cause of death of a northwest Iowa man to “undetermined” after initially investigating the case as a homicide, the Iowa Department of Public Safety reported Monday.

David Davenport, 66, died Oct. 25 of severe head trauma after tenants found him injured inside a rental home on his property near Sergeant Bluff. Authorities learned of his death two days later when a fire damaged Davenport’s home on the property.

A preliminary autopsy conducted at the time ruled Davenport’s death as a homicide.

The Iowa State Fire Marshal’s Office later ruled the fire at Davenport’s home was accidental.

Earlier this month, after investigators reviewed all case findings, the Iowa State Medical Examiner revised Davenport’s cause of death to undetermined.
