A northeastern Kentucky middle school teacher was arrested earlier this month after allegedly hiring someone to kill his mother, Kentucky State Police said, according to WSAZ.

Billy G. Reynolds, 41, was a bus driver for Carter County Schools and also served as a special education teacher at West Carter Middle School in Olive Hill, Superintendent Ronnie Dotson said.

Court records say that Reynolds agreed to hire someone, identifies as a cooperating witness, for $10,000 and gave the person a retainer fee.

WSAZ reported that police learned about the plot on January 15, and he was arrested on Thursday. Reynolds is being held on a $750,000 bond and is expected to be arraigned on Wednesday, the Lexington Herald Leader said.

Police have not revealed a motive for the murder-for-hire plot, but court records indicate that Reynolds’s mother sued him last November. According to court records, the Louisville Courier Journal reported, Reynolds’s parents had prepared a deed in 1993 that would convey their property to their son upon both of their deaths. But, the Lexington paper said, they never recorded that deed.

When Reynolds’s father died last year, the Courier Journal said, Reynolds allegedly stole that paperwork and tried to claim the property for himself. According to the Herald Leader, he recorded a deed that gave the property exclusively to him while leaving his mother with a “life estate” that would permit her to live there.

Reynolds’s attorneys wrote in their response to the suit that the father had told him to record the deed.

The Courier Journal said state police are still investigating the murder-for-hire plot.
