The parents of Ethan Chapin, a 20-year-old University of Idaho student killed in a quadruple homicide near campus over the weekend, say they are frustrated by the "lack of information" from the school and police.

Authorities in Moscow, Idaho, have not announced any potential suspects since the incident took place, leaving community members on edge after the four victims were murdered with what police have described as a knife-like weapon in an "isolated, targeted attack."

"There is a lack of information from the University of Idaho and the local police, which only fuels false rumors and innuendo in the press and social media," Jim Chapin, the victim's father, said in a statement to Fox News Digital. "The silence further compounds our family’s agony after our son’s murder. For Ethan and his three dear friends slain in Moscow, Idaho, and all of our families, I urge officials to speak the truth, share what they know, find the assailant, and protect the greater community."

Chapin, who was one of three triplets born on Oct. 29, 2002, who all attended the university, "lit up every room he walked into and was a kind, loyal, loving son, brother, cousin, and friend," his mother, Stacy Chapin, said in a statement.

"Words cannot express the heartache and devastation our family is experiencing. It breaks my heart to know we will never be able to hug or laugh with Ethan again, but it’s also excruciating to think about the horrific way he was taken from us," she said.
