Miami-Dade Police said Friday they arrested Fernando Granados, 20, in the murder of 18-year-old Tiffany Cabreja. He was being held without bond Friday night and it was unknown whether he has an attorney. Granados’ neighbor Claudia Rojas spoke about what she observed at his house at night. Miami-Dade Police spokesman Det. Roy Rutland, the victim’s father Domingo Cabreja and Miguel Infante, who has been ruled out as a suspect, discussed the case.
