The Mattapan property was listed for $1.15 million when an 18-year-old woman was fatally shot inside; the listing was removed that same day.

A Boston property listed for $1.15 million was removed from the market on the same day an 18-year-old woman was found fatally shot inside the home.

The property at 25 Malta St., in Boston's Mattapan neighborhood, had been offered for sale for $1.2 million on June 1, 2026. The asking price was reduced to $1.15 million on July 7. Then, on July 18, the listing was removed. That was also the day Boston police responded to the address and discovered 18-year-old Yoseliani Ann Marte Ocasio suffering from an apparent gunshot wound inside the residence. She was pronounced dead at the scene.

The timing makes the property's history especially noteworthy for future buyers. The house was actively being marketed when the incident occurred, but as of September 2026, Zillow shows the property off the market rather than currently for sale.

What happened at 25 Malta St.?

According to the Boston Police Department, officers responded at approximately 1:52 p.m. on Saturday, July 18, after receiving a report of a person shot at the property. Officers entered the residence and found Marte Ocasio suffering from an apparent gunshot wound.

On July 30, the Massachusetts Office of the Chief Medical Examiner officially ruled her death a homicide. Boston police identified the victim as Marte Ocasio, 18, of Boston. As of the department's July 30 announcement, homicide detectives were still investigating the circumstances and police had not announced an arrest.

CBS Boston reported that the victim was discovered in the second apartment of the multi-family property, near a rear bedroom.

The house was already for sale

The real-estate timeline is an unusual part of this story.

The property had been listed for $1.2 million on June 1, 2026. The seller reduced the price by $50,000 on July 7, bringing the asking price to $1.15 million. Zillow's listing history then records the property as removed from the market on July 18.

That is the exact date of the homicide.

The Boston Globe reported that a for-sale sign was still visible outside the house as police investigated the scene that afternoon. The listing agent told the newspaper at the time that the property had gone on the market approximately a month earlier.

The property had also been marketed previously. It was listed for $1.025 million in August 2025, later reduced to $989,999 and eventually removed from the market. It returned for sale in June 2026 at the higher $1.2 million asking price.

Who owns 25 Malta St.?

Public-record reporting identifies Conan Harris, husband of U.S. Rep. Ayanna Pressley, as the property's owner. The house was being used as a rental property, and Pressley and Harris did not live there.

A spokesperson for Pressley told news organizations that neither the congresswoman nor her family was involved in the incident and expressed condolences to the victim's family.

The property itself dates to 1910 and is classified as a multi-family residence.

Would a future buyer have to be told about the homicide?

This is where the history of 25 Malta St. becomes particularly relevant to homebuyers.

Under Massachusetts General Laws Chapter 93, Section 114, a property is considered "psychologically impacted" when, among other circumstances, it has been the site of a felony, suicide or homicide. Massachusetts law specifically says that this type of psychological impact is not considered a material fact that must automatically be disclosed in a real-estate transaction.

Massachusetts' own real-estate licensing guidance goes further: absent a specific inquiry from a prospective purchaser or the buyer's agent, a licensed broker or salesperson generally has no duty to investigate or affirmatively disclose murders, suicides or similar psychological stigmas. A seller or real-estate professional still cannot make a false statement or misrepresent a known fact.

That means a future buyer could potentially tour 25 Malta St., inspect its physical condition and evaluate its price without the July 2026 homicide automatically becoming part of the standard disclosure process.

Why researching a property's history matters

A traditional home inspection can tell a buyer about the physical condition of a property. An appraisal can help establish its market value. Neither is designed to provide a comprehensive history of what happened at the address.

That distinction can matter with properties such as 25 Malta St.

The house was listed for $1.15 million when a homicide occurred inside it. If the property returns to the market, that event becomes part of the address's documented history—even though Massachusetts law generally does not require a homicide at a property to be affirmatively disclosed as a material fact.

For buyers who care about that history, researching an address before paying for an inspection and appraisal can provide information that those services were never designed to uncover.

That is the purpose of DiedInHouse.com: helping buyers investigate the history associated with an address before making one of the largest purchases of their lives.

House history first. Then inspection and appraisal.
