WAYNESVILLE, Ind. (WHAS11) -- Police held a news conference at noon on Tuesday, May 14, to update the public and media on their investigation after four people were found shot to death inside a Waynesville, Ind. home Sunday.
Those found dead included 53-year-old Katheryn Burton and her boyfriend, 39-year-old Thomas Smith. Also killed were two 41-year-old Columbus men who were friends of the couple, Aaron Cross and Shawn Burton.
Police said they believe the shootings are drug related.
"Crime scene investigators have recovered the following items from the crime scene. Methamphetamine, several spent shell casings, [and] a knife that was used in one of the homicides," Sheriff Mark Gorbett said.
At this time authorities have interviewed two persons of interest, but have made no arrests.
Coroner Larry Fisher said the four victims were shot in the head; each of the males had multiple gunshot wounds. Kathy Burton was also stabbed multiple times.
"This was a very violent and brutal attack...numerous slugs have been recovered," Fisher said.
Kathy Burton's son, Daniel, discovered the victims after he returned home. He told 911 dispatch his big screen TV was missing and he believed it was a botched robbery.
Sheriff Gorbett said Daniel Burton has been cooperative and is not considered a suspect.
Authorities did recover a rifle near the scene. They are waiting for ballistics to see if that was the murder weapon.
