Lillie Heigl, a law student at Syracuse University, posted her letter on Twitter and it was retweeted hundreds of times, the Star reported.
The university's Panhellenic Council, the governing body for sororities, issued a statement Wednesday morning, saying it has been working to improve diversity and inclusion, the newspaper reported. However, the statement noted that the council is not able to "dictate our chapters' membership or the process of selecting new members."
"As a council that promotes inclusivity, we recognize that people have been harmed by the decisions of our members," the statement read. "And we are committed to engaging all communities in dialogue on these issues to do better in the future."
"Her heart is broken," AnnCatherine's mother, Laura Heigl, told the Star. "She is crushed; she is devastated. But AnnCatherine is AnnCatherine. She kind of picks up the pieces and goes on.
"Sometimes we work really hard for something, or we want something, and just because we want it or we work for it doesn't mean we get it." Laura Heigl said. "We have other things waiting for us down the line, and things will work out."
