A welfare check on a Tuesday in September 2023 at a Third Street home in Clifton, New Jersey, turned up the bodies of 73-year-old Zofia Koc and her 33-year-old son, Peter Koc. Both had fatal gunshot wounds. Investigators reported no sign of forced entry and said there was no ongoing danger to the community.

Officials from the Passaic County Prosecutor’s Office are handling the investigation and have not announced any suspects. Some reports indicate investigators are considering whether Peter fired the shots that killed both himself and his mother, but the final determination is pending further inquiry.

Zofia was born in Frydman, Poland, and immigrated to the United States in 1986. She was an active parishioner at Holy Rosary R.C. Church in Passaic, volunteered with the rosary society, and was known for cooking and leading the walking pilgrimage to the Our Lady of Czestochowa Shrine. If anyone knew the Koc family or has information about that September welfare check, please come forward.
