Four University of Idaho friends are found murdered in an off-campus home.

Police arrived at the home around noon on Sunday, following a call about an "unresponsive person" and found the bodies inside. Police are releasing few details but say the murders were a targeted attack with an edged weapon.

Police assisting in the investigation were reportedly shocked at the amount of blood found at the crime scene. A source told DailyMail that, “there was blood everywhere," with the scene described as “blood oozing through the walls” of the rented home. Blood was also reportedly found on the side of the house and on the back porch.

Moscow police say that Ethan Chapin, 20; Madison Mogen, 21; Xana Kernodle, 20; and Kaylee Goncalves, 21, were found dead at the residence.

Moscow's mayor described the deaths as a “crime of passion.”
