FONTANA Two alarm fire destroys one apartment unit, damages others on 8000 block of Juniper Ave., Saturday morning. The San Bernardino County Fire Department sent a commercial structure fire response to the fire location. The first on-scene engine reported heavy smoke and fire from the windows of a second story apartment unit. There were no reported injuries to civilians. The cause of the fire is unknown and under investigation by San Bernardino County Fire Investigators. However it is believed that the fire grew for some time before being noticed due to the lack of working smoke detectors in the apartment. Estimated damages are currently at least $100,000. The family in the most heavily damaged unit is also reporting one missing dog.
