Cincinnati, OH – Police in southwest Ohio say three bodies have been found in a home, and that carbon monoxide poisoning is the suspected cause.

The Hamilton County coroner’s office was investigating Friday, after police responded to calls from concerned neighbors. Cincinnati police spokeswoman Tiffaney Hardy says the three people were last seen by neighbors Thursday night in the Pleasant Ridge neighborhood.

Authorities say a dog has also been found dead inside the home.

No other details were available immediately.
