Police Found 3 Bodies in a Buffalo Grove House and the Cause Will Surprise You

A hospice worker made a routine call on the morning of June 17, 2026. What officers found when they arrived at a quiet home on Timber Hill Road in Buffalo Grove was anything but routine.

Three members of the same family, all dead within hours of each other. No signs of a struggle. No foul play. Just three people, one house, and a word police used that stopped a lot of people: coincidental.

What Happened at the Timber Hill Road Home

Buffalo Grove Police responded around 7:45 a.m. after a hospice program worker requested a well-being check at the 200 block of Timber Hill Road.

Officers arrived and found two people already deceased inside the home. A third was rushed to Endeavor Northwest Community Hospital in Arlington Heights.

The Cook County Medical Examiner identified all three as the Cavins family. Helen Cavins, 88, and Harold Cavins, 81, were a married couple who lived in the home. Their son, Mark Cavins, 60, was also there. Mark was pronounced dead at the hospital at 9:29 p.m. that evening.

Autopsies were performed on all three. Cause and manner of death remained undetermined as of June 18.

A Son Who Never Left

Helen and Harold had both been enrolled in a hospice program. Mark, their son, was their live-in caregiver.

Dawn Grimes, the Cavins’ daughter, traveled from Pennsylvania after learning the news. She confirmed Mark had been managing their parents’ care full-time. She said she did not yet have details about what happened inside the home.

Police stated the deaths appear to result from “natural causes and/or substance abuse.” The investigation stays open until the medical examiner’s final report is received.

What “Coincidental” Actually Means

This is the part most outlets glossed over.

“Coincidental” is not a closed verdict. It is a preliminary assessment that tells you what investigators do not believe: that someone from outside caused these deaths.

According to the Buffalo Grove Police Department, there is “nothing leading us to believe foul play was involved at this time.” That phrase, “at this time,” keeps the case active. Toxicology results are still pending and those can take weeks.

Buffalo Grove is consistently rated one of the safest suburbs in the Chicago area. Three deaths in one home on one morning still shakes a community, regardless of what the final report says.

Stories like this are rarely as simple as they first appear. A few days earlier, a 5-year-old in Omaha had to call for help after both parents were found shot dead inside their home, another reminder that what happens behind closed doors in quiet neighborhoods is often invisible until it isn’t.

Why This Matters

Mark Cavins was 60 years old, living with his elderly parents, managing their hospice care every single day with no structured support around him.

That situation is far more common than most people realize. According to the National Alliance for Caregiving and AARP’s Caregiving in the US 2025 report, 59 million Americans are currently providing unpaid care to an adult family member, a more than 40% increase over the past decade.

Caregivers who live with the person they are caring for spend an average of 37 hours a week on care duties, with no pay and no built-in relief.

Three people died in that home. Two were elderly and in hospice. The third was the one keeping it all together.

This is not the first time a quiet home held something no one on the outside could see. A person in Spokane refused to evacuate during a wildfire and was found dead the next morning.

In Connecticut, nearly 30 animals were found dead and alive inside a home after police responded to what looked like a routine call. What looks ordinary from the street rarely tells the full story.

Key Takeaways

Wrapping Up

Three deaths. One family. One morning. And a word, coincidental, that does not feel complete until every report comes back.

What we know right now is that a son showed up for his parents every single day inside that home, and none of them made it through a Tuesday in June.
