Touma, an Army dental specialist who had been in the country for less than two weeks after serving three years with the Army in Germany, reported to her assignment at Fort Bragg, N.C., Thursday, June 12, less than 10 days before she was found dead.
The two Fayetteville investigations follow a third high-profile case involving a female member of the military stationed in North Carolina.
In January, the charred remains of Marine Lance Cpl. Maria Lauterbach, who was eight months pregnant, were found in the backyard of Cpl. Cesar Laurean's home near Camp Lejeune, N.C.
Laurean fled the country, and detectives said he left behind a note for his wife in which he denied killing Lauterbach but admitted to burying her remains.
The fugitive managed to avoid capture for several months by living a simple life in San Juan de la Vina, Mexico, until he was arrested in April by Mexican authorities after being spotted walking on a village street. According to witnesses, he did not put up a fight.
Laurean is being held in a Mexico City prison, and North Carolina officials are working through the usual channels to extradite him.
Sportsman, the spokesman for the Fayetteville police, said is was the Lauterbach case that ignited such intense media interest in Touma's death. Wimunc's case has only intensified that interest.
"We've had cases in the past where a soldier was killed and for whatever reason, we never got this kind of attention until now," Sportsman said. "It's unfortunate that these things happen so close together, but what's caused so much attention is what happened in Jacksonville."
Sportsman said that authorities have found no evidence linking Touma's death to Wimunc's disappearance.
