Chilling new details emerge about horrific murder of family of four in New York - as cops arrest illegal migrant

An illegal migrant has been arrested in connection to the brutal murder of a family of four in their upstate New York home.  

Julio Cesar Pimentel-Soriano, 34, was arrested on September 7 and charged with second degree murder after allegedly using a 'sharp object' in the fatal stabbings of the family in their Irondequoit home.

The charred remains of the family - identified as 30-year-old Fraime Ubaldo, 26-year-old Marangely Moreno-Santiago, four-year-old Evangeline Ubaldo-Moreno and two-year-old Sebastian Ubaldo-Moreno - were discovered in their burned-up home in the early morning of August 31, the DailyMail.com previously reported.

Pimentel-Soriano, an immigrant from the Dominican Republic where he is also wanted for another murder from 2019, entered Puerto Rico illegally where he obtained a fake New York ID, according to the Irondequoit Police Department. 

'With that identification, he was free to travel from Puerto Rico to the United States mainland,' officials said. 

Investigators confirmed that the gruesome deaths that left veteran police shaken were homicides after discovering stab wounds in the necks and chest of each victim, reported the New York Post. 

Assistant District Attorney Perry Duckles has said that the police department is looking for a second person involved in the murders. 

'I don’t think this was something random that happened. I do think there is a motive. What that motive is, we are still looking into,' Duckles told WHAM.

Officials also say that Pimentel-Soriano was operating under the alias of Rafael Jose Vargas and had connections in Rochester. 

In the days following the family's murder, relatives and friends gathered to pay tribute to the deceased with a makeshift vigil of balloons and stuffed animals outside of their home on Knapp Avenue. 

The Irondequoit Town Supervisor, Andrae Evans, said days before the arrest: 'Our condolences go out to the family, their friends and neighbors. 

'Because no one, no one deserves this. And whoever you are who did this, you will be brought to justice.' 

Irondequoit Police Chief Scott Peters, who has worked in law enforcement for 32 years, was visibly shaken at a press conference as he described the scene as 'the worst thing I've ever seen' while vowing to 'bring these monsters to justice.'

According to the New York Post, Pimentel-Soriano is being held at the Monroe County Jail without bail and his case has been moved to a grand jury.
