Charleston Fire Chief Karen Brack resigns

CHARLESTON, S.C. (WCIV) — Charleston Fire Chief Karen Brack has announced her resignation from the position.

The chief's final day, according to a copy of a letter sent to ABC News 4, will be April 7, 2017.

In the letter sent to employees of the Charleston Fire Department at around 8 a.m., Brack said, "It has been a great honor to serve this department and community."

The fire chief said she has "mixed feelings" about her position and made the "personal decision" to resign. (VIEW LETTER)

Brack was hired in 2012 as Charleston's first female fire chief. She came to the city with 30 years of experience after a nationwide search. She came to Charleston from Eugene, Oregon.

Brack's decision to resign follows criticism of the city and the department over a promise to the families of the Sofa Super Store fire victims to create a full-scale memorial for the nine firemen lost in the line of duty. But, it's unknown if Brack's decision is related to that issue.
