A deadly explosion in an Orange County, Calif., building that killed one woman and injured three others appears to be intentional and is being investigated as a criminal act, according to an article on the CNN website.
The explosion rocked a medical building in Aliso Viejo Tuesday. It blew out walls and windows, heavily damaging the first floor corner of the two-story building.
The investigation is still in its early stage and authorities are still processing the inside of the building.
"We have not found any type of specific device inside of the building right now that would tell us or lead us to exactly what the device was — if there was a device," according to a Sheriff's Department source.
