“We do believe them to have left the area,” he said in a telephone interview. “We believe somebody came to this residence to do ill, did it, and then has left. We believe it is an isolated, and not a spree, killing.”
He said the authorities had not identified a suspect.
Mr. Swafford said that when the police arrived, they found a back bedroom of the house, a single-level, ranch-style residence, on fire, but he said the fire was not being investigated as a cause of the deaths. The authorities entered through the garage, where they found three of the bodies, Mr. Swafford said. The cause of the fire was not known, he said.
He declined to say where the other bodies were found, and did not identify the victims.
Jeff Chunn, the Morgan County coroner, said the dead included four men and three women, and their relationship to one another was not immediately clear. No one else was in the house when the authorities arrived, he said.
“We are actively processing the scene,” Mr. Chunn said.
Valhermoso Springs is an unincorporated community with a population of fewer than 1,000 people, in the north-central part of the state.
Mr. Swafford said the police had been called to the house in the past to respond to drug-related, trespassing and other complaints. Some of the victims had apparently lived there and “some additional come and go,” he said.
