Saturday night's domestic violence issue and fire are now an arson investigation.

Pasco police said Tuesday Detective Jon Davis, who is the arson expert on the Investigative Services Division, will be examining the home in the 900 block of West Opal.

Police and fire were called there just before midnight Saturday and quickly worked to get anyone still inside to safety. A 64-year-old man was one of those found inside, he suffered a number of burns and was taken to an area hospital in critical condition.

Acting upon tips and evidence the fire may have been related to a domestic violence incident, investigation crews took a look, and now it's an arson case. Police believe the fire may have been deliberately set to hurt people.

More information expected to be released soon.
