MOSCOW, Idaho – The brutal slayings of four University of Idaho students early on a November Saturday marked the first homicides in Moscow in years, according to authorities, but while such crimes are rare, details about the few can be shocking.

Sunday marks four weeks since the slayings of Kaylee Goncalves, 21; Madison Mogen, 21; Xana Kernodle, 20; and Ethan Chapin, 20, in a rental house across the street from the university’s Greek Row. The three women lived there, and Chapin, who lived in a frat house 200 yards away, was visiting his girlfriend, Kernodle. Police have not publicly named a suspect or any persons of interest.

While the city’s last murders came in 2015, in August 2011, a university professor turned a gun on a graduate student with whom he’d been romantically involved, then killed himself in a murder-suicide, school workers told WHD News Digital Friday.

Katy Benoit, a 22-year-old musician and psychology student from Boise, was gunned down in her off-campus apartment months after her romantic relationship with University of Idaho professor Ernesto Bustamante ended.

The reported in 2011 that the police affidavit contained a statement from Bustamante’s friend, Rowdy Hope, who alleged "that Bustamante had multiple handguns and multiple personality disorders…[including] one Bustamante calls a 'psychopathic killer' and another Bustamante calls 'the beast.'"

Police reportedly found Bustamante in a hotel room the day after Benoit’s slaying, dead of a self-inflicted gunshot wound to the head.

"We are shocked and saddened by the death of Kathryn ‘Katy’ Benoit, who was killed outside of her off-campus residence in Moscow last night," the university wrote on Facebook on Aug. 23, 2011. "There is no way to express how devastating the loss of any life can be, but especially someone so young with such potential."

"Her last weeks as a physical being on Earth were filled with excitement and anticipation for her new role as a Teacher's Assistant, where she would be teaching undergraduate classes in Social Psychology and Developmental Psychology," her family wrote in an online obituary. "Katy was a recipient of the Bronze, Silver and, just this past year, Gold Congressional Awards, which are given by Congress to outstanding young Americans with high achievement in volunteer public service, physical fitness and personal development."

Benoit’s death prompted the school to begin an annual event called the Campus Safety Week and Katy Benoit Safety Forum. The university also installed a memorial in her honor on campus.

"The Katy Benoit Safety Month is still held annually and includes a safety forum, a ‘lighting audit’ for students, trainings and other events," Jodi Walker, the school’s executive director of communications, told WHD News Digital Saturday.

Moscow is generally regarded as a safe community, where there have been few slayings over the years.

Court records show the 2015 homicides involved a local man named John Lee, also known as Kane Grzebielski, who later pleaded guilty to three counts of first-degree murder and another count of aggravated battery.

Lee fatally shot his adoptive mother, his landlord and a local restaurateur, the reported at the time, and he injured another man who survived. 

Lee is currently serving a life sentence for the crimes at the Idaho State Correctional Institution.

In 2007, another man, James Leonard, shot and killed Tyler Lee in a driveway in Genesee. He initially claimed self-defense but pleaded guilty to manslaughter and was later freed – only to be arrested last week in Moscow on domestic violence charges just over a mile from the off-campus house where someone killed four students in the early hours of Nov. 13.

Police said his arrest had no connection to the murder investigation.
