ROCHESTER, N.Y. (WROC) – The first suspect named in what Irondequoit police called a "heinous" murder and arson pleaded not guilty in court Thursday. Julio Cesar Pimentel Soriano, 34, was arrested in connection to the death of 30-year-old Fraime Ubaldo, 26-year-old Marangely Moreno-Santiago, 4-year-old Evangeline Ubaldo-Moreno, and 2-year-old Sebastian Ubaldo-Moreno. The family’s bodies were found in a fire at their Knapp Avenue home on August 31. Soriano was cooperative in the courtroom Thursday, communicating with the judge through an interpreter. Investigators said Soriano is wanted for a 2019 murder in the Dominican Republic. He allegedly traveled to Puerto Rico illegally and got a fake New York ID, which he used to enter the US mainland. Irondequoit Police continue to ask for help in locating Luis Francisco Soriano, the second suspect related to this murder. Investigators believe Luis Francisco Soriano fled to Puerto Rico but has family ties in Rochester. Anyone with information is asked to call the Irondequoit Police Department at (585) 336-6000, or to remain anonymous call Crimestoppers at (585) 423-9300. According to Irondequoit police, Soriano is the brother of Julio Cesar Pimentel Soriano.
