Disturbing revelations have surfaced regarding a man charged with the brutal murder of his parents in their Pennsylvania residence, followed by the slaying of his sister upon her discovery of the crime scene.

Kevin Castiglia, aged 55, is now confronting a host of serious charges, which include three counts each of criminal homicide, abuse of a corpse, and recklessly endangering another person. These charges stem from the deaths of his 90-year-old father Fred Castiglia, 84-year-old mother Judith Castiglia, and 53-year-old sister Deborah Castiglia. Since the grim discovery earlier this week, he has remained in custody at the Bucks County jail.

The chilling sequence of events reportedly began on a Sunday, as detailed by authorities. According to court documents reviewed by WCAU, an NBC affiliate in Philadelphia, the initial sign of trouble arose when Deborah Castiglia’s boyfriend, who had not heard from her since the previous day, decided to check on her. His search first led him to her own residence, which was empty, prompting him to head to her parents’ home on Heather Road in Churchville, Pennsylvania.

Upon arrival, he noticed her maroon Kia SUV parked in the driveway. Despite knocking several times, there was no response, and the house was shrouded in darkness. He left, but a lingering concern drove him to return the following day around 2:10 p.m.

This time, his persistence was met with a response. Kevin Castiglia, clad in a robe, answered the door. When the boyfriend inquired about Deborah, Kevin claimed she was not present, suggesting she might have gone on vacation. However, the encounter took a sinister turn as Kevin allegedly brandished a chef’s knife reminiscent of a scene from the movie “Psycho” and threatened, “Don’t ever come here again or I will kill you.”

The suspect reportedly answered the door in a robe, and when the boyfriend said he wanted to speak with his girlfriend, Kevin Castiglia told him she wasn’t there and had likely gone on vacation. He apparently wasn’t finished speaking, allegedly pointing a “Psycho”-type chef’s knife at the boyfriend and warning, “Don’t ever come here again or I will kill you.”

The boyfriend is said to have left and called 911.

The Northampton Township Police Department reported responding to the home “for a well-being check” and that when they arrived, they were “confronted by an adult male armed with a knife.” Kevin Castiglia at this time reportedly held two knives, with one of them apparently having blood on it.

After Kevin Castiglia allegedly failed to answer questions about his family and pointed at least one of the knives at officers, they shot him with a stun gun, but he was apparently unfazed enough to pull the electrodes from his body and retreat into the house where he “barricaded himself.”

A standoff between the suspect and law enforcement lasted five hours, according to authorities, who said officers eventually entered the home and found Fred Castiglia’s and Judith Castiglia’s bodies in their master bedroom and Deborah Castiglia’s body in the kitchen. Kevin Castiglia was found inside of a second-floor bedroom and arrested.

While being treated at a nearby hospital, the suspect allegedly told the doctor, “I hurt someone,” per area ABC affiliate WPVI. Some hours later, his reported admissions apparently went further.

“I killed my parents in their sleep,” he said, according to court documents, as well as, “I killed my sister when she found them.”

Kevin Castiglia is being held by Bucks County authorities without bail. He appeared in court on Tuesday and is expected to return on Feb. 12 for a preliminary hearing. Investigators have not mentioned a suspected motive.
