“Suitcase Killer” Heather Mack is among a group of women claiming to have been sexually abused by a former corrections officer at Chicago’s Metropolitan Corrections Center, The Post can reveal.

Brittany Hall, 31, was indicted by a federal grand jury on March 6 — charged with sexually abusing four inmates while she was the guard in charge of supervising the MCC’s Unit 12.

Hall, who resigned from the US Bureau of Prisons last year, has pleaded not guilty to the charges, which carry a maximum sentence of more than 80 years.
