Officials say charging documents name Kevin Castiglia, 55, in the killings of his parents and sister at a home on Heather Road.
CHURCHVILLE, Pa. — An hours-long police standoff at a Northampton Township house on Monday ended with a knife-wielding man in custody and three people found dead inside, authorities said. Officers first arrived for a welfare check around 2:15 p.m. on Heather Road and called in a regional SWAT team before the breach and arrest later that evening.
Investigators say the case centers on a family home in the Churchville section of Bucks County. The district attorney’s office said the suspect, identified in court papers as Kevin Castiglia, 55, is charged with criminal homicide, abuse of a corpse and related offenses. The victims are his parents, Judith Castiglia, 84, and Fred Castiglia, 90, and his sister, Deborah Castiglia, 53. The scene drew a large police presence as neighbors were told to avoid the area during the barricade. Autopsies were completed Tuesday as detectives worked to confirm timelines, causes and manner of death, and to examine what led to the confrontation that kept streets closed into the night.
Police said the response began when Deborah Castiglia’s boyfriend asked officers to check the home because he could not reach her for days. When he went to the house himself, the man who answered the door allegedly warned, “Don’t ever come here again, or I will kill you,” according to charging documents. Northampton Township officers arrived at about 2:15 p.m. and were met by a man armed with a knife, prompting calls for backup and the South Central Emergency Response Team. As dusk fell, tactical officers used armored vehicles and loudspeakers to attempt a surrender. Video from above showed police breaching the residence. Inside, officers found three bodies — one in the kitchen and two in a nearby room — and took the suspect into custody without shots fired. District Attorney Joe Khan later praised what he called the “admirable efforts” and “heroic restraint” of responding officers.
Authorities said Castiglia was initially detained on offenses related to an assault on another person at the property before homicide charges were added. He was later booked into county jail and ordered held without bail. Detectives from Bucks County and Northampton Township collected knives, clothing and other items from the home for forensic testing. Officials have not released the precise cause of death but said medical examiners completed autopsies Tuesday. Records list the home along Heather Road near 2nd Street Pike, a neighborhood of single-family houses where police closed several blocks during the operation. Prosecutors said they are still building a minute-by-minute timeline from calls, officer body-worn cameras and forensic findings.
The Churchville section of Northampton Township, about 25 miles north of Philadelphia, has seen few major crimes in recent years. Monday’s deployment brought a surge of patrol cars, unmarked vehicles and an armored rescue truck to the quiet cul-de-sac. Neighbors said the Castiglia family had lived in the area for decades and tended to keep to themselves. The district attorney’s office noted that autopsy results and lab work will guide additional counts and help determine whether the victims died the same day or earlier. Officials stressed that there is no broader threat to the public and that the event appears contained to the single household.
Prosecutors said charging paperwork would be updated as laboratory results arrive, including DNA and trace analysis on items recovered from the kitchen and adjoining room. An initial court appearance is expected this week, followed by a formal arraignment in county court. Investigators are also reviewing prior calls for service to the address and interviewing relatives, friends and neighbors. The district attorney’s office said it plans a further briefing once toxicology and full autopsy reports are complete, a process that can take several weeks. In the meantime, detectives are analyzing digital records and phone data to confirm the last known communications from each victim.
On Tuesday afternoon, yellow tape still blocked the property as detectives moved in and out with paper evidence bags. A neighbor described the night of the breach as “sirens, lights and a loud bang” followed by commands over a speaker. Another resident said officers went door to door reminding people to stay inside as the operation unfolded. “They showed restraint and did their jobs under pressure,” the neighbor said. The district attorney echoed that view, saying the response avoided further injury in a tense, close-quarters entry. The boyfriend who reported Deborah missing was cooperating with investigators, authorities said.
As of late Wednesday, the suspect remained in county custody without bail. Officials said the next update could come after preliminary court filings and the release of final autopsy findings in the coming days.
