The ex-boyfriend of the University of Idaho student who was killed says he “lost the love of his life.” Says Aunt. Let’s see Who is Jack DuCoeur and whether Is he the murderer of Idaho students in detail.

Who is Jack DuCoeur?

Kaylee Goncalves, who was murdered at the University of Idaho, had a relationship with Jack DuCoeur. Before the killings, Goncalves and victim Madison Mogen, both University of Idaho students, called DuCoeur a total of ten times.

Two of the University of Idaho students who were killed made several calls to “Jack” before the incident. In a Moscow, Idaho, off-campus residence on Sunday, November 13, remains of Kaylee Goncalves, 21, Madison Mogen, 21, Ethan Chapin, 20, and his girlfriend Xana Kernodle, 20, were discovered. Now it is known that “Jack” is Jack DuCoeur, the ex-boyfriend of Goncalves. The murder has not yet been solved.

Goncalves’ sister Alivea: Statement

According to reports, Goncalves’ sister Alivea claimed on Friday, November 18, that between 2.26 and 2.44 in the morning, her sister made six calls to a friend named “Jack.” Before Goncalves made a second attempt, Mogen contacted him three times.

For the families of the four victims, the Idaho University murder investigation has been difficult and upsetting, but it has also had an impact on the ex-boyfriend of one of the victims, whose life has been turned upside down by suspicion.

According to his aunt Brooke Miller, who talked to the NY Post, Jack DuCoeur dated Kaylee Goncalves for five years and referred to her as the love of his life during that time. Miller thinks that even if Kaylee and Jack had split up, they still would have gotten married.

Kaylee broke up with DuCoeur

Three weeks before the murders, Kaylee broke up with DuCoeur. Although Miller admits her nephew was upset about the breakup, she claims the parting was amicable.

DuCoeur was ruled out by police soon after the November 13 atrocity but has been dogged by ‘ridiculous conspiracies’, his aunt told the New York Post in a new interview. 

She added: ‘He’s not only lost the love of his life, and what we all thought and he probably thought as well, would be his future wife — you know, get married and have kids and all of that.’

Kaylee’s Family Says They ‘Stand Behind Jack 100 Percent’

The couple “were still friends,” according to Miller, who noted that DeCoeur, a mechanical engineering major at the institution, was “clearly” devastated about the split. According to her, the split was amicable and Goncalves “plans to go away.”

It was discovered a few days after the killings that Goncalves and Mogen made at least seven separate calls to Jack just before they passed away, in the very early morning. Steve and Kristi Goncalves, Jack’s parents, have likewise affirmed their support for him “100%.”

DuCoeur mourns Kaylee’s loss 

Miller called online rumors that her nephew was responsible for the killings “crazy conspiracies” and said, “We all know, beyond a shadow of a doubt, that there’s no way that Jack would ever do anything like that to anyone.” She claimed that DeCoeur is having difficulty considering going back to school. He finds it difficult to consider returning to Moscow because Kaylee played a significant role in his life there, she said.

GiveSendGo campaign

Miller is in charge of a GiveSendGo campaign to gather $20,000 for the Goncalves family to pay for a private detective and legal team to aid in the case’s investigation. The Post quoted her as saying, “The very last thing that this family wants to happen is for it to become a cold case.”

Who is Jack DuCoeur?

Jack DuCoeur, 22, and Kaylee Goncalves, 21, dated for five years.


Goncalves posted numerous images of DuCoeur on her Facebook page, whom her parents claim she intended to marry at some point. According to the police, the outgoing calls are related to the ongoing investigation.

Police in Moscow said in a statement that they were aware of many phone conversations made by the victim Madison and Kaylee to a male. The investigation continues in light of this information.

In a statement to Fox, Kaylee’s mother said, “We are supporting him and we know in our hearts and minds and souls and the depths of our souls, Jack is grieving.” “Jack and Kaylee would have wed eventually. After some time, they would have gotten married and had kids. On Facebook, old images reveal she was quite close to DuCoeur, although her Instagram page showed her with pals. They attended athletic events, went boating, and more.

Is he the murderer of Idaho students?

Police were aware of DuCoeur soon after the killings, particularly as a result of the ten calls that Goncalves and Madison Mogen made to him in the hours before the crimes.

DuCoeur was cleared after a police investigation, but the suspicion remained. According to Miller, “half of America” believes that her nephew might be to blame.

DuCoeur has received harsh treatment online, with others accusing him of being the culprit. By the way, Goncalves’ family has backed DuCoeur and asserted that he was not responsible for her passing.

“We all know, beyond a shadow of a doubt, that Jack would never do anything like that to anyone,” Miller told the Post. After six weeks, the murders are still a mystery, at least to the general public.

On November 20, 2022, when asked if Jack DuCoeur had been exonerated in the killings, the police chief responded, “Everything that we have collected from those calls, we have followed up on, we have cleared, and we believe there is no connection there.”

The chief earlier in the news conference identified a number of people who had been exonerated (the former roommates, the private driver who drove them home), but he omitted DuCoeur from the list.

Later, the police provided another update. They stated that they did not think the private party who drove the girls was involved and that one of the roommates’ phones was used to make the 911 call. According to investigators, the victims were found on the second and third levels of the house, they reported.
