A family of four was killed in a Murray, Kentucky house fire in November 2015. First responders found 24-year-old Marisol Hernandez, her 29-year-old husband Bulmaro Arellano, their five-year-old son and an 18-month-old daughter in the charred home. Autopsy findings reported Marisol died of a single gunshot wound to the face and Bulmaro sustained multiple gunshot wounds to the head and body. The children’s official causes of death were pending, though investigators believed they died of smoke inhalation after the fire was set to hide the crime.

Investigators arrested 21-year-old Pascasio Y. Pacheco Arellano, a nephew of Bulmaro, on multiple charges including four counts of murder, first-degree burglary, first-degree arson and tampering with physical evidence. Detectives noted injuries on the suspect that they said were sustained during the incident; he received medical treatment before being taken into custody. Prosecutors indicated they planned to present the matter to a grand jury.

Does anyone have information about the family or that night in November 2015 that could help investigators?
