A Westport mom and daughter were found dead in their Lyndale Park home in Connecticut Thursday. The victims’ names have not been released by law enforcement. It’s unclear whether the mother and 7-year-old girl were murdered. An investigation is underway to determine the cause of death and a possible motive.

The police responded at the family’s home on the north side of town around 4 p.m. Thursday after a report that a woman was unresponsive inside the home. Police found the woman dead inside and proceeded to check the rest of the home for other residents. They soon discovered a 7-year-old girl who was also deceased, though authorities have not revealed the cause of the death for either victim.

The Westport Police Department issued a statement via Facebook, announcing the “untimely deaths” of a Westport mom and daughter in their Lyndale Park home. In the statement, the department reported that “at approximately 4:00 p.m. on this date, the Westport Police Department along with Westport Emergency Medical Services and the Westport Fire Department responded to a home in Westport on a report of an unresponsive female.”

Westport Police launched an official investigation, though it is only in its initial stages. The department is being assisted by the State Police Major Crimes Unit, according to the statement. The statement claims that it “appears to be an isolated incident” and the department does “not believe that there is any active threat to the community.”

The names of the deceased are withheld from the public record at this time. As of Friday morning, the circumstances were not revealed. But residents of the tony enclave Lyndale Park are wondering if the Westport mother and daughter were murdered.

It is unclear whether authorities are looking into a possible homicide, but they are currently trying to piece together what happened. According to the Connecticut Post, the mother and daughter lived in a two-story residence on the corner of Weston Road and a private drive, located just off the Merritt Parkway.

The front of the property is surrounded by a cut stone wall, topped with a wrought iron fence. The road leading to the home was lined with police cars, and some residents claimed they had a hard time getting through the neighborhood.

Police were spotted standing at the front entrance of the home, and one team of investigators was seen searching the grounds in front of the house, by the built-in garage. There have been no official updates by law enforcement since the investigation was opened.

The 7-year-old daughter attended school in the Westport school district. The district superintendent, Thomas Scarice, announced that the Coleytown Elementary School and Stepping Stones Preschool were closed Friday, but are open to both parents and students for mental health services.

In an email to parents Thursday night, Scarice wrote that “late this afternoon, we were informed of the untimely and tragic loss of one of our parents and her beloved daughter.” He continued, writing that “there are no words that could console the sense of sorrow we feel by this unspeakable tragedy. We want to express our deepest condolences to all those impacted by this heartbreaking loss.”

The school district has “begun to mobilize all of [its] resources to provide the necessary support to [its] students and faculty, according to Scarice’s email, which offered links to online mental health resources.

Questions still plague parents in the community, who are worried about a potential threat to the neighborhood, though police believe there is no active danger. No possible motive has been discussed by the Westport Police. The community is in shock by the events, given that Lyndale Park is considered a safe neighborhood.

Thoughts and prayers for the Westport mom and daughter were shared beneath the Facebook announcement. Many of those who offered prayers were residents in the same community.
