Many of the details in this story are disturbing.
FAYETTE COUNTY, Ky. (LEX 18) — The former girlfriend of an Indianapolis man charged in the 2015 stabbing death of a 6-year-old Versailles boy told jurors Tuesday that Ronald Exantus wasn't sleeping well and cried frequently in the week leading up to the slaying.
Lauren Burgess took the stand in a Lexington courtroom as Exantus' defense began making its case.
Burgess said Exantus proposed marriage to her out of the blue after attending church. She said they had smoked marijuana together and that Exantus had taken NyQuil to help him sleep but that it didn't work.
She said Exantus called her from jail, but often spoke in a different language. She said he blamed Burgess for making him "do this."
Earlier, Kentucky's chief medical examiner took the stand, describing in sometimes graphic detail the mortal injuries Exantus is charged with inflicting on the 6-year-old Woodford County boy a 2015 stabbing attack.
As the jury looked at a diagram of a child's body, Dr. William Ralston described the injuries cataloged by his office after Logan Tipton's death: stab wounds to the neck and back of the head, a metal fragment found inside Logan's head, bruises to the forehead and right shoulder.
In the end, Ralston said, Logan died of blood loss within minutes of being attack.
The testimony comes as prosecutor near the end of their case against Exantus, a dialysis nurse, who police and prosecutors say broke into the Tiptons' Versailles home and killed Logan with a butcher knife as he slept.
In testimony shown last week, Exantus told police just after the killing that he had gotten lost in Versailles and referenced TV shows in describing why he stopped near a family's home before allegedly breaking in and slaying the boy.
Defense attorneys have said Exantus suffers from mental illness and was psychotic when he killed the boy while prosecutors have tried to show he knew what he was doing.
Prosecutors on Tuesday also played another graphic video recording from a police body camera from the night of the killing, prompting Logan's grandmother to leave the courtroom in tears.
On it, an officer can be heard cursing Exantus and admonishing him to "show some remorse."
"What the hell did you do to that little boy?" a Versailles police officer asks Exantus. "What did you do to him?"
"I'm sorry, gentlemen," Exantus says. "I'm sorry. I'm sorry, God."
