Carl Swain, aka, Cowboy, was arraigned in U.S. District Court in Savannah Thursday morning.
Swain is charged with the murder of a Fort Stewart soldier, Spc. John Eubank, late last year.
The U.S. Attorney's Office confirmed Thursday that Swain and Eubank's wife are brother and sister.
"Oh yeah, I was shocked," said Matthew Hurst, who says he is their third sibling. "I thought it was suspicious. Something ain't right, smells fishy.
Hurst says he, Swain and Eubank's wife all have the same mother, but they went into the fostercare system at an early age.
"I'm the black sheep of the bunch. I decided I wanted to make something better out of myself," said Hurst.
Hurst says there is much more to this case than authorities are sharing with us, and is certain more people are involved and it's only a matter of time before something comes out.
Swain entered a plea of not guilty to the murder.
He is charged for willfully, maliciously and with premeditation beating Eubank to death on Fort Stewart back in November of 2013. The indictment also suggested this was a murder for hire.
Swain will remain in custody. No bond was requested.
However Swain's attorney did ask that he be transferred to the Chatham County Detention Center so he is closer than Statesboro, where he is currently being held.
This is a case punishable by death, however its not clear yet if the U.S. Attorney's Office will seak the death penalty.
In order to seek the death penalty they will need U.S. Attorney General's approval.
