The family of a prominent businessman who's been missing for nearly four years says there's been a break in the case.
John Glasgow's brother says John Brawner, an inmate at the Faulkner County Jail, told police that he knew where Glasgow's body was buried.
Authorities reportedly have searched that location and found nothing, but will now be using sonar equipment to continue searching.
John Glasgow, the CFO of CDI Contractors, was last seen driving away from his home early in the morning of January 28, 2008.
His vehicle was found unlocked on Petit Jean Mountain a day later.
KATV's Christina Munoz spoke with Roger Glasgow tonight. He says the family still hopes that John is alive somewhere, but if he's not they want to see the perpetrator prosecuted to the fullest extent of the law.
