Andy Byler told police that about two weeks before his wife's murder, a suspicious person arrived at their home at night, the documents said. Andy Byler said a bald, white man with a white beard came to the house, and "when confronted, the male inquired about purchasing the house," the documents said.
A woman who lives near the victim, Katie Byler, told police that a man named John had been a driver for her husband, whom she's recently separated from, the documents said. When John wasn't available one day, John suggested his dad, Shawn, could work as a driver, the court documents said. The husband "accepted the ride from Shawn and immediately got an uneasy feeling about him," the documents said.
Katie Byler and the two people she lives with told police that, from December to February, they "had very odd experiences with this individual they know as Shawn," the documents said.
They told police that after Shawn gave Katie Byler's husband a ride, "Shawn would randomly show up at their residence," the documents said.
"On one occasion, Shawn drove a Jeep to their residence and parked in their driveway," the documents said.
They said Shawn -- wearing all black and carrying a small pistol in a holster on his belt -- "was walking around their property looking aimlessly into their fields and his speech made no sense," the court documents said. "He was inquiring as to when and where they attend church and that he wished to go with him."
