Officials now say a two-alarm fire Wednesday at the former site of a New York City-run shelter in Orange County is being investigated as suspicious. 

The Chester Fire Department tells News 12 that an old barn filled with mattresses and a nearby storage shed were fully engulfed in flames when they got to the now-closed Camp LaGuardia grounds around 9 p.m.

Orange County owns the property. News 12 has a call out to the county for more information.
