Terry Todd Wedding, 27, of Depoy, was charged with four counts of murder, said Bryan Pitney, public information officer for the state police's Madisonville post. Wedding lived next door to two of the victims, Joey T. Vincent and his wife, Amy, Pitney said.
Authorities responded Sunday morning to a call reporting gunshots at the Vincents' home and found Mr. Vincent, 29, and Mrs. Vincent, 22, dead in the driveway, Pitney said.
The couple's 3-year-old daughter was found at the home but was not hurt.
Upon further investigation, authorities found the bodies of a man and a woman in a field three miles from the Vincents' home Sunday afternoon, Pitney said.
Their identities had not been released pending notification of relatives, but they were neighbors of the Vincents, he said.
Wedding was in his home when authorities arrived to question him about the Vincents' deaths. He surrendered to police and was charged later Sunday night, Pitney said.
"We believe that we have a good solid motive ... but right now I can't discuss what that motive may be," Pitney said.
Wedding was lodged in the Daviess County Jail, and bond had not been set.
Joey Vincent was an eight-year veteran of the Greenville Police Department and also was a minister at New Cypress Baptist Church. He was scheduled to attend training in Ohio next month to be certified as a police chaplain, Pitney said.
