An Irvine home where police found three members of the same family dead in what investigators described as an apparent murder-suicide is back on the market.

58 Riverboat, Irvine, CA 92602

The house at 58 Riverboat in Irvine, California, is currently listed for $2,699,000.

From the listing photos, it's a polished luxury home in the gated Orchard Hills community, complete with a pool, spa and carefully landscaped exterior.

There is nothing in those photographs to suggest what police discovered inside the house on April 6, 2022.

Three members of the Poirier family had been dead inside for so long that their bodies were severely decomposed.

Here's the history of 58 Riverboat — before, during and after the tragedy — and how the property eventually returned to the market.

Before the Deaths: The Poiriers Buy 58 Riverboat

58 Riverboat is a relatively new house.

Built in 2017, the two-story home is located in the Varenna neighborhood of Orchard Hills, a gated Irvine community surrounded by rolling hills and avocado groves.

Property records show Serge and Karina Poirier purchased the newly built home from Tri Pointe Homes in 2017 for $1,436,500.

The approximately 2,766-square-foot house has four bedrooms, multiple bathrooms, a two-car garage and a lot of just over 5,200 square feet.

For the next several years, it was the Poirier family home.

Then, sometime before April 2022, something happened inside.

Exactly when remains one of the unusual parts of the story.

Relatives Hadn't Heard From the Family for More Than a Year

On April 6, 2022, Canadian authorities contacted the Irvine Police Department on behalf of concerned relatives.

Extended family members said they had not heard from the family living at 58 Riverboat for more than a year.

At approximately 10:30 that morning, Irvine police officers went to the house to conduct a welfare check.

They entered the residence.

Inside were three severely decomposed bodies.

Police initially described them as three adults and said there were no signs of forced entry. Investigators weren't looking for an intruder.

A handgun was also found inside the home.

Police said there were indications that what happened was domestic in nature and that they were investigating the deaths as an apparent murder-suicide.

NBC Los Angeles reported on the discovery that day:

The Yard Gave No Obvious Sign Something Was Wrong

One detail from the original investigation helps explain how a house could apparently sit for such a long time without anyone realizing what was inside.

The front yard was being maintained.

Irvine Police Lt. Bill Bingham told NBC Los Angeles that his understanding was that the homeowners association maintained the home's front yard.

That meant someone looking at 58 Riverboat from the street wouldn't necessarily see an abandoned or badly neglected property.

The landscaping could continue to look maintained even though the people who lived inside had apparently not been heard from for more than a year.

It's an eerie detail when looking at photographs of the property today.

From outside, it looked like another well-kept home in a gated Irvine neighborhood.

Police Identify Serge, Karina and Morgan Poirier

Later that month, authorities released the identities of two of the people found inside.

The Orange County coroner identified them as Karina Poirier, 55, and Serge Poirier, 63.

Investigators believed the third person was the couple's 21-year-old son, Morgan Poirier. At the time of the April 29 report, authorities said DNA testing was being used to positively confirm his identity.

Police also revealed another significant detail.

All three had suffered gunshot wounds.

A gun was recovered at the scene.

Police said the evidence appeared consistent with a domestic incident that ended in a murder-suicide.

The Los Angeles Times reported the identification and additional findings:

The publicly available reports reviewed by DiedInHouse do not identify which member of the family investigators believed shot the others. We are not going to speculate beyond what authorities publicly reported.

What Happened to 58 Riverboat After the Murder-Suicide Investigation?

For a time, 58 Riverboat remained tied to the Poirier estates.

Then the house went back on the market.

In October 2023, roughly a year and a half after police discovered the bodies, the property was listed for $1.98 million.

It went under contract later that month.

On November 22, 2023, 58 Riverboat sold for $1.95 million.

That was more than $500,000 above the $1,436,500 price Serge and Karina Poirier had paid for the newly built home in 2017.

The property had a new owner.

Its history, of course, remained attached to the address.

The House Became a Rental

Just days after the 2023 sale, 58 Riverboat appeared on the rental market.

It was offered for $7,500 per month in November 2023 and subsequently rented.

The property returned to the rental market again in April 2025, this time with an asking rent of $8,500 per month.

Real-estate records indicate it rented in May 2025 for $8,600 per month.

By then, three years had passed since police entered the home and discovered the Poirier family.

The house was occupied again.

Then, in 2026, the owner decided to sell.

58 Riverboat Is for Sale Again

The property returned to the sales market in May 2026 with an asking price of $2.85 million.

The price was later reduced to $2.799 million.

On August 18, a new CRMLS listing was entered at:

$2,699,000.

The home remains listed for sale.

The current listing highlights its gated Orchard Hills location, open floor plan, chef's kitchen, downstairs bedroom, second-floor loft, primary suite, swimming pool, spa, outdoor fireplaces and paid-off solar system.

Current property details and listing history can be viewed here:

The asking price represents an increase of $749,000 over the property's $1.95 million sale price in November 2023.

Whether a buyer believes the home is worth $2.699 million is a question for the market.

Whether its history matters is a question each buyer has to answer for themselves.

The House Is Also Being Offered for Rent

There is another interesting development in the property's history.

While 58 Riverboat is being marketed for sale, a separate CRMLS rental listing appeared on September 9, 2026, offering the property for $9,500 per month.

So someone interested in the house today doesn't necessarily have to purchase it.

They could rent it.

That makes the history of the address potentially relevant to tenants as well as buyers.

Would a Buyer Know Three People Were Found Dead Here?

That's an important question.

Walk through 58 Riverboat today and you're looking at a modern luxury home.

A home inspector can evaluate the roof, electrical system, plumbing, HVAC and other components of the property.

An appraiser can help determine what the house is worth.

Neither service is intended to give you a complete history of everything that happened at the address.

That's a different type of research.

California also has specific laws concerning deaths at residential properties.

California Civil Code §1710.2 addresses disclosure involving deaths at a property, including deaths occurring more than three years before an offer to purchase or rent and responses to direct inquiries from prospective buyers or tenants.

The date matters in this case.

Police discovered the Poirier family at 58 Riverboat on April 6, 2022.

The home is now being offered for sale in 2026.

California's statute can be read here:

https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?sectionNum=1710.2.&lawCode=CIV

Buyers with questions about how the law applies to a particular transaction should consult an appropriate California real-estate professional or attorney.

Would the History Change Your Decision?

For some buyers, probably not.

They may look at 58 Riverboat and see a four-bedroom home in a desirable Irvine community with a pool, upgraded interior and gated location.

For another buyer, learning that a mother, father and son were found dead inside in an apparent murder-suicide could completely change how they feel about purchasing the property.

Both reactions are personal.

DiedInHouse isn't here to tell someone whether they should or shouldn't buy a house where a death occurred.

We believe buyers should have the opportunity to learn about a property's history and decide for themselves.

Preferably before spending money on the next steps in the buying process.

Research the House Before Paying for the Inspection and Appraisal

Homebuyers can spend hundreds of dollars on a home inspection.

An appraisal can add hundreds more.

If something in the history of a house would cause you to walk away from the purchase, wouldn't you rather discover it before paying those expenses?

That's why we suggest researching the history first.

House history first -> Then the inspection ->Then the appraisal.

Then make your decision.

If the history doesn't bother you, continue moving forward.

A DiedInHouse report doesn't replace a home inspection, appraisal, title search, seller disclosures or professional advice. Those services serve different purposes.

The question we're helping buyers investigate is simple:
