Kentucky State Police are investigating the death of the Bell County Magistrate Saturday in the Bell County Jail.
Earlier this month, Ricky Goodin, 51, of Pineville, was charged with solicitation to commit murder.
A preliminary investigation indicates that Goodin began having a seizure while inside his cell and no foul play is suspected, police said in a news release.
The guards at the detention center were notified of Goodin having a seizure by his cellmates, and guards contacted Bell County EMS, who took him to the Pineville Community Hospital. Goodin had another seizure while at the hospital, where he was pronounced dead at 5:55 a.m. Saturday.
An autopsy will be performed at the State Medical Examiner's Office in Frankfort.
Earlier this month, Kentucky State Police spokesman Shane Jacobs said detectives received information about threats made by Goodin to arrange for the death of someone.
Goodin was being held at the Bell County jail on a $1 million cash bond.
In March, Goodin was arrested on multiple charges; authorities said he sold prescription drugs and methamphetamine out of his pawn shop.
