A Quiet Labor Day at Home
On the morning of September 3, 2001, 35-year-old Mike Labaso was spending a quiet morning with his two children at their home on Long Island, New York.
It was Labor Day, and Mike had the day off. He worked as a Drug Enforcement Administration (DEA) agent on a task force that targeted major drug trafficking organizations. His job was stressful and dangerous, and he rarely had much time to relax.
Even at home, there was always something to do. His old house needed regular repairs, and the yard required constant maintenance. But that weekend, Mike and his wife, Dawn, had decided he would put those responsibilities aside and focus on his family.
That morning, Mike was sitting on the couch with his children, watching cartoons while Dawn was out running errands.
For once, he was doing exactly what he had planned: enjoying time with his kids.
The Strange Noise in the Backyard
After a while, Mike’s seven-year-old son asked if they could go outside and play soccer. Mike agreed and got up to put on his shoes.
As he bent down to tie them, he heard a strange noise coming from the backyard. It sounded like groaning or grinding, but he could not identify the source.
The sound caught his attention. Mike stood up and looked through the glass patio door, hoping to see what was happening outside. However, there was nothing obvious to explain the noise.
His work as a DEA agent had given him reasons to worry about his family’s safety. He had helped bring down drug operations, and he knew that some of the people affected by his work might want revenge.
Although he had no evidence that anyone was outside, he could not completely ignore the possibility that something was wrong.
Mike decided to check the backyard before allowing his children to go outside.
He told them to stay on the couch while he went to investigate. Then he opened the door and stepped into the yard.
It was a decision that would cost him his life.
Dawn Returns Home and Searches for Mike
A few hours later, around 12:30 p.m., Dawn returned from running errands with groceries.
She entered the house and called for Mike, asking him to help carry the bags. When he did not answer, she took the groceries into the kitchen herself.
She continued calling for him, but there was still no response.
Then she looked into the living room and saw her two children sitting on the couch, watching television. Mike was nowhere to be seen.
Dawn asked the boys where their father had gone. They could only shrug and tell her they did not know.
His absence seemed strange. Mike would not normally leave his young children alone without telling anyone where he was going.
Dawn began searching the house. She could not find him or any explanation for his disappearance.
Eventually, she reached the glass door leading to the backyard.
When she looked outside, she saw something horrifying.
What Happened to Mike Labaso?
The strange noise Mike had heard was not caused by an intruder. It came from a dangerous structural failure beneath his backyard.
The previous day, a company had visited the property to drain an underground sewage tank. The tank had been causing plumbing problems, and the work was intended to address the issue.
However, the old tank had deteriorated over time. During the pumping process, it collapsed under the pressure, allowing waste to leak into the surrounding ground.
The failure created a large underground cavity beneath the backyard.
As the ground above it weakened, the surface began to sink. The sound Mike heard was reportedly the earth slowly collapsing into the space below.
How the Backyard Sinkhole Formed
A sinkhole can develop when the ground beneath the surface loses its ability to support the soil above it. In Mike’s case, the damaged underground sewage tank and the leaking waste created a dangerous cavity.
The grass and soil initially appeared stable, but the surface was no longer properly supported.
When Mike stepped onto the affected area, the thin layer of ground gave way beneath him.
He fell into a pit approximately 25 feet deep, filled with concrete debris and sewage.
The backyard that had seemed safe only moments earlier had become a deadly trap.
An 18-Hour Rescue Operation
Mike’s fall left rescue workers facing a difficult and dangerous recovery operation.
The depth of the sinkhole, along with the sewage and unstable material inside it, made reaching him extremely challenging.
Rescue crews worked for approximately 18 hours before they finally recovered his body.
Unfortunately, Mike did not survive the accident.
His death was especially tragic because he had not been investigating a criminal threat or responding to a dangerous situation at work. He had simply stepped outside to investigate an unusual noise in his own backyard.
The accident also left his wife and children to cope with the sudden loss of a husband and father.
Why Underground Sewage Tanks Can Be Dangerous
Mike Labaso’s death highlights the risks posed by old underground structures that deteriorate out of sight.
Sewage tanks, septic systems, buried chambers, and other underground installations can weaken over time. If the structure collapses or the surrounding soil shifts, the ground above it may become unstable.
Warning Signs of Ground Collapse
Some potential warning signs include:
- Unexplained cracking or sinking in the soil.
- Depressions forming in a lawn or yard.
- Ground that feels unusually soft near an underground tank.
- Sudden changes in drainage or persistent plumbing problems.
- Unusual cracking, grinding, or settling sounds from below the surface.
These signs do not always mean a sinkhole is forming. However, unexplained changes near an old underground structure should be taken seriously.
How to Reduce the Risk
Property owners should arrange inspections of aging underground tanks and septic systems, particularly when plumbing problems suggest structural deterioration.
Any suspected ground collapse should be treated as a safety hazard. People should keep away from the affected area and contact qualified professionals rather than attempting to inspect or repair it themselves.
After work involving an underground tank, the surrounding ground should also be checked for signs of damage or instability.
The Tragic Death of Mike Labaso
Mike Labaso spent his working life dealing with the dangers associated with drug enforcement. On Labor Day in 2001, he was finally taking a break to enjoy time with his family.
A strange noise interrupted that peaceful morning. Concerned, he went outside to investigate, unaware that the ground beneath his feet had become dangerously unstable.
The collapse of an old underground sewage tank had created a hidden sinkhole in his backyard. When the surface gave way, Mike fell into the pit and died.
His death was a reminder that serious hazards are not always visible. Sometimes, the most dangerous situations develop quietly beneath places that appear completely ordinary.
