Neighbors said they heard gunshots at around 4 p.m. local time Thursday, Dec. 28, and called the police. Two men and a woman were found dead inside, and officials didn’t find anyone else inside the home, the paper reported.

Police told The Associated Press that they don’t know the relationship between the people who died. It’s also unclear if they knew the gunman.

“We are really early in the investigation right now so things are very fluid, and developing as I speak,” Patty told the Review-Journal. “At face value, this is an obvious homicide that is cause for concern,” Patty said.

Streets in the area were blocked off as police investigate.

No other details were provided. No one is currently in custody, KDWN reported.

No gun was found at the scene.
