The grieving sister of Kaylee Goncalves – one of four University of Idaho students mysteriously murdered over the weekend in a house near campus— broke her silence in a touching tribute Monday.

Alivea Stevenson, 26, released a family statement to Fox News Digital calling Kaylee "our defender & protector" after the tragic killings.  

"One of the most painful experiences has to be to sum up an entire person in a paragraph," the statement reads. "Who they were and what they loved & what they wanted in life. Our sister can't be packaged up in a box with a neat bow."

Kaylee, one of five siblings, loved her puppy, Murphy, her family and "the way mimosas looked but not really the taste," according to the statement.

As the middle child, she fiercely looked out for her family and "didn't hold back on love, fights or life."

Before her tragic slaying, Kaylee had plans to move to Texas for a tech job that started Jan. 1, her family said. The native of Rathdrum, Idaho, was also looking forward to an upcoming trip to Europe.

"She'd never stop fighting for us and demanding the truth and justice and neither will we," her family wrote.
