My sister and kids lost all in fire

My sister Carmela just moved in to her new apartment on 4-14-2017.  As they slept  in their new home, a fire broke out in the early morning of 4-15-2017.  They all woke up to a loud explosion.  They quickly noticed that there was a fire and ran out as quickly as possible.  My sister had everything in boxes, all of my nieces and nephews clothing were burned. Along with all of her belongings They lost EVERYTHING in the fire.  She has a teenage girl 13, a little boy 7, and a little girl 5. 
They ran  out with out shoes and were taken to the hospital with minor burns and lacerations. 
I am asking for help so she can re locate and and start all over again. They are lucky to be alive.  Anything will help.  Thank you so much.
