Sister and 2 kids in desperate need

My sister and two kids are in desperate need for any help they can get. Their father and husband suddenly passed away on April 28 with a massive heart attack. Came in house, closed door behind him and feel in floor. Luckily, my sister got her sense together and called 911. They worked on him for an hour before they pronounced him deceased. This is when their world fell apart. It took 2 to 3 hours for the medical examiners to get there for his body....the kids would not leave their mama.  His son Dylan is highly autistic and unable to help with home requirements or work. His daughter Hannah is a home body who just wants to be at home to help mom and brother, with her own special needs...my sister Gaye has not had a job outside of home in 20 years. Bernice was always the provider, the way he wanted it. 
Even though dad is gone the bills do not stop...
Please any help even if it is .25 cents all adds up and can put food on the table...
God bless you all and please pray for this lonely family...
Amy Cowen, sister of Gaye Mcdonald.
