BOWLING GREEN, Ky. — On an August morning in 1998, the Morrison family of Columbus, Ohio, set out on what was supposed to be a week-long camping trip to Kentucky’s Mammoth Cave National Park. David and Sarah Morrison, along with their teenage daughters Sarah Jr. and Jenny, never arrived.

Their disappearance became one of the Midwest’s most enduring mysteries — until, two decades later, a land surveyor’s drone flight over remote forestland revealed a massive sinkhole filled with rusted, stacked cars. Among them: the Morrisons’ 1996 yellow Honda Accord.

What followed was an investigation that uncovered a multi-state conspiracy involving corrupt law enforcement, insurance fraud, and at least 43 murdered families — a scheme authorities say operated in plain sight for more than 10 years.

A Family Vanishes

Jake Morrison was 14 when his parents and sisters disappeared. Sick with the flu, he had stayed home that morning while the rest of his family loaded their camping gear and pulled out of the driveway.

“That was our tradition,” Morrison said in an interview. “Dad would honk twice. Mom would blow me a kiss. My sister would yell something sarcastic out the window. And that was the last time I saw them.”

Local and state police searched the Morrisons’ planned route to Mammoth Cave. No car, no witnesses, and no physical evidence emerged. The case went cold within months.

The Drone Discovery

In late 2018, land surveyor Dale Rivers was mapping timberland for a logging company in eastern Kentucky when his drone’s camera captured something unusual — a sinkhole roughly 60 feet wide, choked with vehicles.

“I’ve been surveying 15 years and never seen anything like it,” Rivers said.

When Kentucky State Police reviewed the footage, one vehicle stood out: a corroded yellow sedan matching the Morrisons’ Honda. Investigators called Jake Morrison, now 34 and running the family’s small construction business.

“I’d been waiting for that call for 20 years,” he said.

A Graveyard of Cars — and People

Detective Amanda Cross of the Kentucky State Police Cold Case Unit took the lead.

“What Dale found wasn’t just a dump site,” Cross said. “It was organized. Cars were deliberately positioned and stacked, suggesting long-term, systematic use.”

In the sinkhole, forensics teams identified partial license plates linked to at least eight other missing families, including a Tennessee couple and their children who vanished in 1999.

Inside the Morrisons’ vehicle, investigators found a child’s purple hair tie and a worn stuffed elephant — both confirmed by Morrison as his sister Jenny’s belongings — and a chilling message scratched into the rear window: Help us.

Following the Paper Trail

A background check revealed a disturbing pattern: Between 1995 and 2005, the Morrisons’ car dealer, Rick Brennan of Brennan’s Auto Sales in Ohio, had sold vehicles to at least 12 families who later vanished.

“On the surface, his business was clean,” said FBI Special Agent Frank Torres, brought in after the case crossed state lines. “But when you cross-referenced customer lists with missing persons reports, the overlap was staggering.”

Brennan’s suspected partners: Sheriff Dale Hutchkins of rural Kentucky — whose department saw 47 unsolved disappearances during his tenure — and Margaret Pierce, an insurance claims adjuster who processed millions in payouts for stolen or missing vehicles.

According to investigators, Brennan would identify families with valuable insurance coverage and predictable travel plans. Hutchkins’ deputies would intercept them on remote roads, after which the families were murdered and their vehicles dumped in the sinkhole. Pierce would process the claims, and the three split the proceeds.

The Break in the Case

In a wired meeting arranged by law enforcement, Morrison confronted Brennan at his dealership.

“When I mentioned Highway 31E, where my family was taken, his reaction told us everything we needed,” Cross said.

Brennan was arrested within hours. A search of his office uncovered customer profiles, route maps, and “post-operation reports” detailing the Morrisions’ 1998 murder and 42 other cases.

Faced with the evidence, Brennan admitted the conspiracy had claimed 212 victims. He identified a hunting cabin owned by Hutchkins as a burial site.

The Excavation

The cabin, deep in Daniel Boone National Forest, had long since collapsed. Beneath it, FBI forensic anthropologist Dr. Sharon Kim’s team found multiple burial pits.

“In the first day, we recovered remains matching the Morrisons’ demographics,” Kim said. “Positive IDs came later through dental records and DNA.”

In total, remains from 14 families were recovered. Cause of death in many cases was blunt force trauma.

The Operation Continues

Just weeks after Brennan’s arrest, new evidence surfaced: photos of recent car buyers in a hidden lockbox at the dealership, discovered by Brennan’s son, Mike. Some were dated within the past month.

One of those families — the Taylors — had recently disappeared. Investigators suspected Brennan’s younger brother, Terry, who had taken over the business, was continuing the scheme.

The Sting

Working with Morrison, Cross, and Torres, the FBI set a trap using the Patterson family, recent customers planning a trip through the Smoky Mountains. The family was briefed and protected by undercover agents.

On the day of the operation, Terry Brennan bypassed the original intercept point and blocked the Pattersons’ SUV on a rural highway, shotgun in hand. Before he could fire, an FBI sniper killed him.

“He was using the exact same playbook his brother had used 20 years earlier,” Torres said.

Justice and Aftermath

Brennan’s cooperation led to multiple arrests, including former deputies and a state detective. The total victim count may never be known.

Morrison buried his family in Columbus in a service attended by investigators and surviving relatives of other victims.

“He never gave up,” Cross said. “Because of that, dozens of families got answers.”

A New Mission

Morrison has since founded the Morrison Family Crisis Center, providing resources for families of missing persons. He now consults with law enforcement nationwide on cold cases.

“This isn’t about bringing the dead back,” he said. “It’s about making sure the living never have to stop looking.”

The investigation has prompted changes to interstate missing persons protocols and renewed scrutiny of unsolved family disappearances tied to travel routes and vehicle purchases.

“This case shows how greed can corrupt at every level,” Torres said. “But it also shows the difference one determined person can make.”
