An elderly couple were shaken this week after discovering human blood throughout their home with no explanation why it was there.
Elmer and Viola Stacy, both in their 90s, made the gruesome discovery on Tuesday, when they found the blood splattered in the kitchen and several other rooms, mostly on the floors and low on the walls. They apparently were home when the mess was made.
Scott County Sheriff's Capt. Mike Brown said testing determined that the blood was human.
It "was almost all over the house," Brown said. "It looked bad. It makes you take a step back and say, 'Whoa, what happened?'"
The rural Davenport couple hopes that someone will have information on why the gore covered parts of their home. They both were checked out by a doctor, and police will run tests to determine if the blood matches their DNA.
The Stacys stayed with a daughter while a bloodstain pattern analyst from the Des Moines Police Department checked out their home.
Brown said the house was as tidy as before the mess was discovered.
"It's just bizarre," he said. "We have a ton of questions."
Police barricaded the area surrounding the house, near Interstate Highway 280 and U.S. Highway 61, for a time as cadaver dogs and their handlers searched the area.
They found nothing that indicated where the blood may have come from, officials said.
