GLASGOW, Ky. — A small Kentucky community is mourning the deaths of all four aboard a small plane that crashed last weekend on a flight from Tennessee.

State police Trooper Jeremy Hodges told the Bowling Green Daily News three men were pronounced dead at Sunday’s crash site of a Piper PA-32 in some woods in Barren County in southern Kentucky. The fourth victim, a boy, was pronounced dead at a hospital.

The victims were identified by authorities as 41-year-old Kyle P. Stewart, 40-year-old Quinton “Doug” Whitaker, 41-year-old Scott T. Foster and his son, 15-year-old Noah Foster.

Mayor Eddie Girdler of Somerset, Kentucky, said the four had left Friday for a weekend hunting trip and were returning at the time, their deaths leaving a void in his community where flags were lowered to half-staff. Stewart was a dentist, Whitaker was Somerset police chaplain, Foster an attorney and Noah was a high school sophomore.

Reports said preliminary information indicate the plane left Union City, Tennessee, on Sunday for Somerset when the plane entered clouds and the pilot turned to instrument-only flying, according to National Transportation Safety Board air safety investigator Brian Rayner. The investigator said the radar track of the aircraft became “erratic” before communications were lost. He didn’t identify who was piloting the plane.

The wreckage, which was found in some woods, was being moved elsewhere for examination, Rayner said Tuesday.

He said the NTSB was seeking to determine the cause of the crash.
