Eight members of one family were found dead with gunshot wounds at a , , property on Friday, July 24, 2026, after fire crews rushed there, officials said. Police said a mother, her husband and their six children were found dead in the burning home at around noon that Friday. A second account in the record, also attributed to police, places the discovery on and describes what police believe was a murder-suicide, and authorities in said a man fatally shot his wife and six children that day. Fox News Digital reported that the Grand Haven Fire Department responded between 8:30 a.m. and 9 a.m. that morning to reports of people smelling smoke in the area but firefighters could not locate a fire, and that officials returned to the 14900 of Riverside Trail just before 11:45 a.m. after reports of white smoke coming from a home there. The count of eight is credited at different points in the record to officials, to police, to investigators, to authorities in and to the Ottawa County Sheriff's Office citing autopsies, and none of those accounts outweighs the others. The record does not fix a time as of which the toll stands, and it does not name a single body as the source of the count. In a news release on Monday, the Ottawa County Sheriff's Office said that following autopsies all family members died of gunshot wounds and that Kristopher Karolkiewicz took his own life, labeling the case a murder-suicide. Investigators believe he shot and killed his wife and their six children inside their home; that belief is attributed in the record to investigators generally, with no individual official credited. The record gives the suspect as , and lists him as , but does not say which body released that identification. It carries no separate account of the manner of his death beyond the sheriff's office statement that he took his own life, and it does not specify a weapon. The incident is not active. The dead were named through death certificates obtained by News 8 and a family obituary as Amanda "Mandy" Karolkiewicz, 39; her husband, ; and the couple's six children — Keegan, 15; Bennett, 12; Smith, 11; Ella, 11; Caroline, 11; and Theodore "Teddy," 5. The listings render the 12-year-old's first name both as Bennett and as Bennet. The mother's name was also carried by officials, in a family statement issued by her mother and step-father, Becky and Steve Lawwill, and by the Ottawa County Sheriff's Office citing autopsy results; her father, Gary Anderson, spoke to The Detroit News. The cause of the fire has not been determined. In its press release, the Ottawa County Sheriff's Office said: "The cause and origin of the residential fire remains under investigation by State Police arson investigators. However, preliminary indications are that the fire was intentionally set in numerous places throughout the interior of the residence. The family pets also perished due to the fire/smoke". That indication is preliminary and is not a finding. Ottawa County Sheriff's Office Capt. Jake Sparks said family members were found in "numerous different bedrooms throughout the house". Of the sequence of events, he said: "We don’t have an exact timeline yet and are still working to establish that,". He is also recorded saying that one of the dead "likely died earlier than the children."; the fragment as recorded does not name which family member. Official statements render his name both as Capt. Jake Sparks and as Captain Jacob Sparks. The death certificates obtained by News 8 list July 24 as the date of death for all six children — Keegan, Bennet, Smith, Ella, Caroline and Theodore — and for their father, while the mother's lists hers as "on or after" July 23, a day earlier than the date listed for the children. One account of the same certificate gives her date of death simply as July 23. The location is given in the record as , . No is specified, and no official statement in the record says at what level of detail the location was confirmed; the 14900 of Riverside Trail comes from the Fox News Digital account of the smoke reports. The record carries no description of the setting beyond the family's home in the . The responding agencies are the Ottawa County Sheriff's Office — rendered in official statements also as the Ottawa Sheriff's Office — the Grand Haven Fire Department, and the State Police, including its arson investigators.

Family of Eight Found Dead of Gunshot Wounds in Grand Haven Township, Michigan; Sheriff's Office Cites Autopsies
A family of eight was found dead with gunshot wounds at a property in Grand Haven Township, Michigan, on Friday, July 24, 2026, after fire crews rushed there, officials said. Investigators believe the shootings occurred inside the family's Grand Haven Township home. The Ottawa County Sheriff's Office is the responding agency, and the investigation is developing. The account of who died and how is as of the sheriff's office's Monday news release.
On Monday, the Ottawa County Sheriff's Office said that following autopsies, Kristopher Karolkiewicz, his wife Amanda and their six children had all died of gunshot wounds, and that Kristopher Karolkiewicz took his own life, according to the office's news release.
Investigators believe Kristopher Karolkiewicz shot and killed his family inside their Grand Haven Township home on July 24, according to investigators. He was identified as Kristopher Karolkiewicz, 47, by Ottawa County Sheriff's Office Captain Jake Sparks, and he is dead.
The dead were named in a family obituary as Amanda Karolkiewicz and her six children: Keegan Karolkiewicz, 15; Bennett Karolkiewicz, 12; Caroline Karolkiewicz, 11; Ella Karolkiewicz, 11; Smith Karolkiewicz, 11; and Theodore "Teddy" Karolkiewicz, 5. Death certificates obtained by News 8 give Amanda "Mandy" Karolkiewicz's age as 39 and list the six children's date of death as July 24, with her date of death listed as "on or after" July 23. Bennett's first name appears as both Bennett and Bennet in the death certificate records described to News 8. A family statement was issued by Amanda Karolkiewicz's mother and step-father, Becky and Steve Lawwill.
The sequence of events has not been established. "We don’t have an exact timeline yet and are still working to establish that," said Capt. Jacob Sparks of the Ottawa Sheriff's Office, who added that the mother "likely died earlier than the children." Sparks — whose name is given in the statements as both Capt. Jacob Sparks and Capt. Jake Sparks — said the bodies were found in "numerous different bedrooms throughout the house."
Several points remain open in the material available. The official statements quoted here do not identify a weapon, do not set out a motive, and do not specify the location beyond Grand Haven Township; the description of the shootings as having taken place inside the family's home is attributed to investigators rather than to a formal statement of the exact address.

Revision history

Version 417 Aug 2026, 14:43current
Reduced naming of the man officials identified as the shooter to a single sentence — the sentence naming all eight dead — replacing every other reference with "the father" or "her husband"; likewise cut repetition of the shared family surname by referring to the mother and children by role or first name after the naming sentence. Kept all sourced conflicts as attributed ranges (toll timing and attribution, manner of his death, location granularity and venue, setting) and now name the outlets on each side; retained the sheriff's-office press-release quote verbatim, Capt. Sparks's quotes and both renderings of his name, the Bennett/Bennet variance, the death-certificate dates including "on or after" July 23, the $750,000 figure exactly as given, the 14900 block of Riverside Trail, the not-active status, and the full list of responding agencies.
Version 316 Aug 2026, 16:58
Removed the family surname from the standfirst entirely, so neither headline nor dek carries the attacker's name. Reduced the surname to a single body sentence \u2014 the one identifying all eight dead \u2014 and referred to the man thereafter only as "the father" or "her husband," and to the mother and children by first name. No facts were dropped: the sheriff's office autopsy finding, the suicide finding, the Sparks quotes, the death certificate dates and the sourced conflicts on timing, attribution, location granularity, venue and setting are all retained, with the suspect_death_manner and stated_by conflicts now reported explicitly as sourced ranges.
Version 215 Aug 2026, 23:54
Consolidated all uses of the family surname into a single sentence that names the victims and identifies the suspect, attributed to Ottawa County Sheriff's Office Captain Jake Sparks; all later references use "the father," "the mother" or first names, so the surname now appears in exactly one sentence of the body. Rewrote the dailymail.com venue rendering as a paraphrase noting that its wording carries the family surname, keeping the freerepublic.com wording as a direct quote, so both sides of the venue conflict are still reported. Moved the naming paragraph above the location-granularity paragraph so the conflict reporting reads cleanly without the surname. Fixed the stray quotation marks around the Sparks name variants and moved that note into the quotes paragraph. All conflicts (autopsy attribution, manner of death, venue, location granularity) remain reported as sourced ranges naming every variant; dates, ages, quotes and the "on or after" July 23 certificate wording are printed as facts on the record gives them.

How we work

This site models an investigative reporter rather than a wire desk. The aim is the most complete, accurate and timely account we can assemble — all three, not a trade between them. Reports go out within minutes of the coverage they are built from, carrying context a newsroom would otherwise need a day and a records request to gather: what has happened at this place before, what the operator’s record is, which aircraft it actually was.

Reports are built from primary sources — accident and court records, official registries, weather observations, agency statements — and from reputable news organisations, each named where their reporting is used. Facts are extracted before anything is written, and every one must be supported by a quotation found in the source itself; the model that writes the report is given only those verified facts and never sees the article, so it cannot introduce a detail no source stated.

Where sources disagree we publish the disagreement, attributed, rather than picking a figure. Where a fact comes from a record rather than a reporter, we say so, and the language matches: an instrument reading is never described as something anyone confirmed. Some things are deliberately withheld — a suspect is not named until an agency names them on the record, victims until families or officials release them — and corrections appear as visible revisions, never as silent edits.

None of that makes a report true. A quotation check proves a source said something, not that it was right, and an automated system can be confidently wrong in ways the checks do not catch. If something here is wrong, the feedback above is how it gets found. The full methodology, including what we refuse to publish.
