The August burial of a World War II veteran in the Vicksburg National Military Park led to the discovery of at least two unmarked and unrecorded graves, park officials said Thursday.

Who is buried in the plots in a tract paralleling North Washington Street, when they were buried or why no records exist is an ongoing mystery, VNMP Superintendent Michael Madell said.

“Every time we find an answer, there are three or four more questions,” Madell said.

Members of the Tallahassee, Fla.-based Southeast Archeological Center have been taking scientific readings over a 1.9 acre tract. As of Thursday, the five-member team has collected and analyzed data from about 1/4 of the cemetery, which is the final resting place for veterans of World War II and Korea.

Park historian Terry Winschel said the unmarked graves are not those of Civil War soldiers. The cemetery ceased burying veterans in 1961, unless previous reservations and arrangements had been set.
