“We extend our deepest sympathies to the family members and teammates of the deceased soldier,” Fort Jackson Commander Brig. Gen. Patrick R. Michaelis said.

battalion post on Saturday said Cahoon’s family is asking people to collect pull tabs and give them to local Ronald McDonald houses as a fundraiser in her memory.

Cahoon’s death is being investigated, according to a statement released by Fort Jackson.

The Cahoons were human resource specialists in the battalion’s Bravo Company, The State reported.

Human resource specialists must undergo eight weeks and five days of advanced, infantry training at Fort Jackson, the newspaper reported.
