Hannah Elizabeth Graham, an 18-year-old student at the University of Virginia, disappeared early Saturday walking home from a party, FoxNews.com reports.

According to WTVR, police said Tuesday that Graham was last spotted on surveillance video outside of McGrady’s Pub in Charlottesville, Virginia, at approximately 12:45 a.m. Saturday.

Friends reportedly received a text from Graham at approximately 1:20 a.m. Saturday saying that she had gotten lost.

According to WCAV, Hannah was also spotted on Friday evening around Camden Plaza, an off-campus apartment complex.

“Those of us who know and love Hannah know that she would not disappear without contacting family or friends,” Hannah’s family said in a statement obtained by The Associated Press. “She is highly responsible and organized. We express our sincere gratitude to law enforcement and everyone who is involved in the search for Hannah.”

Hannah is reportedly described as a white female, about 5′ 11” tall with light brown hair and freckles. The AP notes that the FBI, the Virginia State Police, the Albermarle County Sheriff’s Office and several other law enforcement agencies are assisting with the search.
