Family of Four Found Dead, Housekeeper Discovers Bodies After Mother's Curious Final Post

What began as an ordinary workday for a housekeeper quickly unraveled into one of the city's most disturbing family tragedies — hidden behind a locked door on the sixth floor.

A family of four was found dead in their sixth-floor apartment on Aguirre Street in the Villa Crespo neighborhood of Buenos Aires, Argentina.

The discovery was made at around 1:30 p.m. on Wednesday, May 21, 2025, when the family's housekeeper arrived for work and found the body of one of the couple's two sons near the front door.

Police were immediately alerted, and the remaining three family members were later found deceased in different rooms of the home. Authorities identified the deceased as Bernardo Adrián Seltzer, 53; his wife, Laura Fernanda Leguizamón, 50; and their two children, Ian, 15, and Ivo, 12. All four had died from stab wounds.

According to reports from Infobae, the man's body was discovered in one of the apartment's bedrooms. The knife used in the attack was also located in that same room.

The woman's body was found in the bathroom, and their other son's body was discovered in his own room. There were no signs of forced entry, and the apartment door was locked, suggesting no intruders had entered.

A handwritten letter was found in the kitchen, containing what police described as rambling text. Investigators from the Buenos Aires Homicide Division, along with the National Criminal and Correctional Prosecutor's Office No. 5 under César Troncoso, treated the case as a triple domestic homicide followed by suicide.

The evidence at the scene led investigators to believe that Leguizamón was responsible for the killings.

Seltzer, originally from the Buenos Aires town of Rivera in the Adolfo Alsina district, was known as a specialist in grain markets and sales. He had reportedly consolidated his wealth during the soybean boom in the 2000s.

Sources confirmed that there had been no previous reports of domestic violence involving the couple. However, it was revealed that Leguizamón had been receiving psychiatric treatment.

According to her sister, she may have stopped taking her medication. The housekeeper, who worked regular shifts at the home, noted that her employer's behavior had changed over the past week.

The housekeeper, who arrived for her scheduled shift at noon, told police that she found one of the children lying in a pool of blood near the entrance.

Shortly after, the rest of the apartment was searched and the other three bodies were discovered. Medical personnel confirmed all four individuals were deceased upon arrival.

The mobile criminalistics unit, summoned by Prosecutor Troncoso, carried out evidence collection at the scene. Based on the collected data, investigators concluded that Leguizamón committed the murders before taking her own life.

As police conducted their investigation, the only living being removed from the apartment was the family's cat. Officers were seen carrying the animal in a crate, treating it with care. La Nacion reported that the cat appeared to be the sole survivor from the tragic scene.

Authorities continue to review the circumstances that led to the tragedy, though all signs indicate a murder-suicide initiated by the mother.

With no history of violence in the household and limited insight into the family's recent life, the case has left both investigators and the public grappling for answers. The investigation remains ongoing.

The last public Facebook post shared by Leguizamón on March 1, 2025, has since drawn attention. It featured several cheerful photos of the family smiling, dining out, and enjoying quality time together.

The caption, written in a disjointed and erratic style, reflected on a short getaway to Mar del Plata — a coastal city in Argentina.

"A quick Mar del Plata trip. It started. Then got canceled. Then changed — we did what we could. It is what it is. Rain. Sun. The hotel. Driving. The theater. The storm. Yes. No." She called the trip "special," citing reasons like a promise she made, the upcoming school start, and a visit to Aquopolis.

The post also mentioned packing details. "Five of us. More suitcases. More little seats. Beach mat. Towel. Tiny shovel. Mates. Less sleep. Way more attention."

She ended with seemingly random remarks about people they encountered, such as La Gri and Nelly, and local spots like Punta Mogotes and Ricardo from Punta Pizzas.

Leguizamón's erratic tone in her last Facebook post may be linked to her reported mental health issues, though nothing can be said with certainty.

The unanswered questions surrounding the Buenos Aires case echo another recent family tragedy. Just days earlier, a similar incident emerged — this time in northwest Montana.

Reports revealed the details surrounding the death of a family of four, including a mother and two children, who reportedly lost their lives at the hands of the patriarch. According to authorities, the father took their lives, despite the couple's online presence reflecting a warm and loving family through the photos they shared on Facebook.

Authorities in Kalispell, a city of just under 30,000 near Glacier National Park, responded to a 911 call made shortly before 6 a.m. on May 11, 2025.

The call came from inside a home in Silverbrook Estates, a planned community bordered by the Stillwater River, known for its newly built homes and tranquil setting. According to Kalispell Police Chief Jordan Venezio, the call was placed by 33-year-old Nicholas Olson-Hartley.

When officers arrived at the scene, they found Nicholas, his wife, 27-year-old Katie Olson-Hartley, and their two daughters, just seven months and six years old, had been fatally shot. Authorities believe Nicholas committed the crime before turning the gun on himself.

"It appears Nicholas Olson-Hartley took the lives of his young family before calling 911," Chief Venezio stated. "After making the phone call to dispatch, he took his own life."

The police chief noted that the statements made during the 911 call were "concerning," though specific details have not been disclosed. Investigators spent the day gathering evidence and interviewing neighbors, ultimately determining that the incident was a murder-suicide.

The tragedy has sent shockwaves through the tight-knit community of Silverbrook Estates, where homes often list for more than one million dollars. In a statement released Monday, May 12, Westcraft Homes — the neighborhood's developer — expressed deep sorrow over the loss.

"We are deeply saddened by the recent tragic loss of one of our Silverbrook families," the statement reads. "Our thoughts, prayers, and heartfelt condolences go out to all who are grieving — especially the extended family, neighbors, and friends affected by this unimaginable tragedy."

The company also urged residents to appreciate each other and show love, expressing, "Let us honor the lives lost by fostering kindness, reaching out, and lifting one another up. Let us support, listen, and show compassion. Together, we can help by choosing compassion and knowledge."

Before their deaths, both Katie and Nicholas shared heartwarming photos on their social media pages that painted a picture of a once-loving family.

Katie's Facebook page, verified by NBC News, features joyful images of their daughters and affectionate snapshots of the couple.

In the comment section of a 2023 post beneath a photo of her and Nicholas surrounded by autumn leaves, a loved one of Katie's named Kayla Knaff wrote, "This is how people look at each other in movies when they're in love."

On Nicholas' profile, he, too, shared endearing snaps of himself and Katie looking happy together. According to Montana court records, Nicholas had filed a marriage license application in 2018 that included his wife's name.

This tragedy in Montana comes just one day after a similarly devastating, suspected murder-suicide in Nebraska, where four members of a family — parents and their two teenage children — were found dead.

Law enforcement officials in both states are continuing their investigations, trying to piece together the motives behind these unimaginable acts.

At this time, we wish to express our most heartfelt condolences to the extended family of both the Olson-Hartleys and the family in Nebraska.

We also wish to extend our condolences to all their loved ones, friends, and communities as they mourn such significant losses. We hope for their healing amid their time of grief. RIP, dear Olson-Hartleys and the family in Nebraska.
