MARTIN COUNTY, Ky. (WMDJ) — Three men have been federally indicted in connection with an alleged assault at the United States Penitentiary Big Sandy in Martin County.

A federal grand jury charged Gilbert Saldana, Edward Rogriguez and Alfred Fabrow with assault with a dangerous weapon with intent to do bodily harm. The indictment was filed Aug. 27 in U.S. District Court for the Eastern District of Kentucky.

Prosecutors allege the assault occurred July 6 within the boundaries of USP Big Sandy. According to the indictment, the three men allegedly assaulted a person identified only by the initials R.G.G. using a homemade stabbing instrument.

The charge carries a maximum penalty of 10 years in prison, a $250,000 fine and three years of supervised release. A $100 special assessment and restitution, if applicable, could also be imposed.

An indictment is an accusation, and the defendants are presumed innocent unless proven guilty.
