Suffolk County, NY — Detectives from the Suffolk Homicide Squad are intensifying their investigation into the tragic death of 15-year-old Liam Delemo, who was fatally stabbed during a house party over the weekend. The devastating incident has left the quiet suburban community reeling in shock and sorrow, as friends, classmates, and neighbors struggle to come to terms with the loss of a bright young life cut far too short.
Authorities said the stabbing occurred late Saturday night at a home not far from Liam’s own neighborhood. Investigators believe an altercation broke out among a small group of teenagers at the gathering, which quickly escalated into violence. By the time first responders arrived, Liam had suffered multiple stab wounds. Despite desperate efforts by paramedics, the 15-year-old was pronounced dead shortly after being transported to a nearby hospital.
Liam’s parents, Mike and Andrea Delemo, described their son as an exceptional young man—an honor student, an athlete, and a kind soul whose laughter filled their home. They said Liam had mentioned plans to attend the party, which was taking place just around the corner from their residence, and they trusted he would return home before curfew.
“He was responsible, mature beyond his years,” said his father, Mike Delemo, his voice heavy with grief. “We told him to have fun but be safe. We never imagined we’d get a call like that.”
That call came from one of Liam’s close friends, who frantically told the couple that Liam had been stabbed. “It didn’t feel real,” Mike said. “One moment, everything was normal—and the next, our world was shattered.”
Neighbors recalled the sound of sirens and chaos late that night, as police cars and ambulances flooded the usually peaceful street. Since then, mourners have gathered outside the Delemo home and at the scene of the incident, leaving flowers, candles, and handwritten notes expressing heartbreak and solidarity.
Suffolk detectives are pursuing multiple leads and have interviewed several partygoers who were present at the time of the stabbing. Authorities have not yet named a suspect but confirmed that they are searching for a male individual believed to have fled the scene shortly after the attack. They have urged anyone with photos, videos, or information from the party to come forward.
“This is a devastating tragedy,” said Suffolk Police Commissioner Rodney Harrison. “A young life has been taken senselessly, and we are committed to finding the person responsible and bringing justice to Liam and his family.”
At Liam’s school, grief counselors have been made available as classmates mourn the loss of a beloved friend described as intelligent, kindhearted, and always ready to help others. Teachers remembered him as a student with big dreams—a teenager who loved science, soccer, and spending time with his younger sister.
“He had such a bright future,” one teacher said tearfully. “This shouldn’t have happened.”
As the investigation continues, the Delemo family is surrounded by an outpouring of community support, but no amount of comfort can fill the void left behind. A vigil is being planned in Liam’s memory, where friends and loved ones will gather to honor his life and call for an end to the violence that claimed it.
“We want people to remember Liam for who he was—a beautiful, kind boy who brought joy to everyone around him,” Mike said. “We just want justice for our son.”
