(CBS/AP) WAYNESVILLE, Ind. - Four people were found shot to death Saturday night inside a home in Waynesville, Ind., reports CBS affiliate WISH.
Authorities say those killed included homeowner Katheryn Burton, 53, Thomas Smith, 39, Aaron Cross, 41, and Shawn L. Burton, 41.
Smith's aunt told the station that he had dated Burton for nine years.
No suspects are in custody and officials were not involved in a manhunt, police said.
"We still have crime scene techs and criminal investigators at the scene and anticipate them being there for quite a length of time," Bartholomew County Sheriff Mark Gorbett told WISH.
The person who called 911 after discovering the bodies is a son who lived with his mother and stepfather in the home, Gorbett said. He discovered the bodies when he came home from work, according to police.
The three male victims were found in the living room and the woman in the bathroom, police said.
A Bartholomew County sheriff's dispatcher said early Monday that she had no new information available about the investigation into the deaths.
