A former soldier was arrested Thursday in Florida in connection with the death of a pregnant service member at an Army base in Germany 21 years ago, federal prosecutors said. 

Shannon L. Wilkerson, 42, is charged with first-degree murder in the Nov. 3, 2001 death of Pfc. Amanda Gonzales at Fliegerhorst Kaserne, then an Army base in Hanau, Germany, the Justice Department said. Wilkerson was a soldier at the time before he was later discharged from active duty in 2004.

Her cause of death was asphyxiation. 

At the time of her death, Gonzales served as a cook in the Headquarters Supply Company of the 127th Aviation Support battalion.
