911 Audio Reveals Frantic Response To Michigan Family Murder-Suicide

Haunting new 911 audio captures the frantic moments after a caller reported a house full of smoke after a Michigan father who had allegedly been unfaithful shot his wife and six children and set their home ablaze.

“Grand Haven Township for a residential fire at 14936 Riverside Trail,” a dispatcher is heard saying on the audio obtained by Fox News. “White smoke coming out of the window. House is full of smoke seen from the outside and smells electrical.” 

A Grand Haven home matching the address in the 911 audio is a sprawling 4,103-square-foot, five-bedroom, four-bathroom property estimated to be worth about $760,000, according to Zillow. The home, last sold in 2019, boasts an upgraded interior and a backyard pool surrounded by a private wooded area.

On the morning of July 24, firefighters entered the home near the eastern shore of Lake Michigan to search for victims, only to discover a horrific scene inside.

Police said Kristopher Karolkiewicz, 47, used a handgun to fatally shoot his wife, Amanda Karolkiewicz, 39, and the couple’s six children before taking his own life. Authorities have not released the identities of the couple’s children, who included four boys, ages 5, 11, 12, and 15, and two 11-year-old girls. Two of the children had been adopted into the family. The medical examiner determined all eight died of gunshot wounds.

To outsiders, the family looked like something out of a Hallmark movie. But new details reveal a marriage falling apart and a mother of six living in fear.

Amanda posted under the Reddit username “MandyK1179,” under which she detailed her troubled marriage and accused her husband of infidelity, according to The Detroit News. The Holland Sentinel said it independently verified the account by matching details about the couple, including where they lived, their ages, and their occupations.

The Daily Wire previously reported on one Reddit post in which Amanda lamented that her husband had a thing for office interns.

“I was the intern at the company we both worked for. He was divorced and older than me… fast forward ten years and five kids, he was cheating with the intern again- the same age I was when I was the intern,” she wrote in the ‘As One After Infidelity’ subreddit. “I was five babies in, and was actually not in bad physical shape, but I was in the trenches of little kids, and just couldn’t be who I was before.”

According to the posts, Amanda also wrote that she was “terrified” and would not have remained married if not for their children.

The account further alleged that Kristopher’s infidelity led the couple to marriage counseling and therapy. 

“I don’t feel bad still. He towers over me and destroyed me mentally,” the account commented two years ago, describing the time she shoved her husband after learning of his affair. “It felt like I was being assaulted and needed to fight back. I think it’s a fight or flight thing.”

In one May 2024 post, she said: “We have six kids, so the idea of leaving is insanely terrifying,” according to Detroit’s WDIV.

Just weeks before the murder-suicide, Amanda posted multiple TikTok videos of trips she took to Canada and China earlier this month with her boys and two adopted daughters.

One video, dated July 16, shows her dressed in a traditional Hanfu style of clothing, along with her two daughters, in Hangzhou, the capital of China’s Zhejiang province.

The mom of six and dedicated teacher shared a video of the family’s July 4 celebration at Stony Lake in Michigan. The video shows a quick glimpse of the stone-faced father lighting a firework. Another TikTok video, dated June 24, shows Amanda getting ice cream with her boys in Quebec, Canada, writing: “The most delicious, produced-to-order ice cream — unlike anything we have ever eaten!” 

Police believe the fire was intentionally set in multiple locations throughout the interior of the home. The family’s pets also died from the fire or smoke inhalation. Authorities said they do not believe any suspects remain at large.

“This is far more than a news story. The situation personally impacts dozens, if not hundreds, of people in the county,” said Capt. Jake Sparks with the Ottawa County Sheriff’s Office.
