Danbury Police say they are investigating all aspects of a 16-year old girl's death over the weekend.  Police said as reflected in the multiple responses to their Facebook post about the death of Hailey Nailor, the Special Victims Unit is looking into a possible social media influence. Should the investigation reveal a criminal aspect, Police say they will inform the public at an appropriate time.  Nailor recorded a Snapchat video from the roof of the Danbury Mall parking garage on Saturday before jumping to her death.  School officials are also looking into what they described as disturbing social media comments posted immediately after the suicide.
