SHREVEPORT, La. (AP) — A Louisiana sheriff says four people are in jail in connection with an investigation into firearms that were stolen while in transport to a gun distributor.

Caddo Parish Sheriff Steve Prator says Con-way Freight contacted his office on Oct. 15 about a pallet containing 63 Colt AR-15s missing from its terminal. Prator says none of the guns has been recovered.

The guns are described as black, 5.56 mm, semi-automatic with a law enforcement carbine and 16-inch barrel. They are valued at $800 each.

Parish and federal authorities have booked 21-year-old Cameron Johnson, of Keithville; 22-year-old Luther M. Williams Jr., of Shreveport; 44-year-old James D. Minor Jr., of Keithville; and 31-year-old David McNeil, of Keithville.

It was unclear whether the men have attorneys.
