The sister of Kaylee Goncalves, one of four University of Idaho students murdered early Sunday, urged students to flee the small college town as long as the suspect in the killings remains at large.

 "To the students of the University of Idaho that are still staying around campus, leave. Your grades are severely less important than your lives," wrote Aubrie Goncalves in an Instagram post Wednesday.

"No one is in custody and therefore no one is safe," she warned.

Police have not named any suspects or persons of interest in the gruesome murders of Goncalves, 21, Ethan Chapin, 20; Xana Kernodle, 20; and Madison Mogen, 21.

"You guys are not safe until this sicko is found," the post continued. "If the person who did this is capable of killing four innocent people, they are capable of killing more. The last thing I want is to have another family experience what I, and my family is experiencing now."

Aubrie dismissed online rumors that the students overdosed on drugs and called the accusations "extremely hurtful."

In a tribute to the slain victims, Aubrie vowed to ensure their killer is brought to justice.

"I am so sorry you guys were taken so young," she wrote. "I promise each and every one of you, I will do everything in my power to help find, and put your murderer in prison to rot for the rest of their life."

Kaylee was one of five children. Another sister, Autum Goncalves, blasted police for initially calling the killings an isolated, targeted attack that posed no threat to the greater community.

Jazzmin Kernodle remembered her older sister, Xana Kernodle, and her love of dancing.

"She had the best friends in the whole world, and all she wanted to do was live life to the fullest," Jazzmin wrote on Instagram. "She was always the life of the party and was a dancing queen. I could go on and on, but she truly was a once in a lifetime [sic] type of person."
