A body was found in a Maryland garden-style apartment building a day after an explosion and fire there and investigators are looking into the possibility of a "criminal, intentional act," officials announced late Thursday.

Montgomery County fire and police officials said a body was found in the rubble by the front of a Potomac Oaks Condominium building in Gaithersburg, news outlets reported.

An explosion ripped through two buildings Wednesday morning, injuring at least 14 people, two of them critically, and destroying or severely damaging nine units, officials said.

Only one man remained hospitalized Thursday, Fire and Rescue Service Chief Scott Goldstein said.
